Methods Summary
public abstract char	charAt(int index) Returns the character at the specified index. An index ranges from 0 to length() - 1. The first character of the sequence is at index 0, the next at index 1, and so on, as for array indexing. param index the index of the character. return the character at the specified index of this string. The first character is at index 0. exception IndexOutOfBoundsException if the index argument is negative or not less than the length of this string.
public abstract int	compareTo(com.sun.org.apache.xml.internal.utils.XMLString anotherString) Compares two strings lexicographically. param anotherString the String to be compared. return the value 0 if the argument string is equal to this string; a value less than 0 if this string is lexicographically less than the string argument; and a value greater than 0 if this string is lexicographically greater than the string argument. exception java.lang.NullPointerException if anotherString is null.
public abstract int	compareToIgnoreCase(com.sun.org.apache.xml.internal.utils.XMLString str) Compares two strings lexicographically, ignoring case considerations. This method returns an integer whose sign is that of this.toUpperCase().toLowerCase().compareTo( str.toUpperCase().toLowerCase()). Note that this method does not take locale into account, and will result in an unsatisfactory ordering for certain locales. The java.text package provides collators to allow locale-sensitive ordering. param str the String to be compared. return a negative integer, zero, or a positive integer as the the specified String is greater than, equal to, or less than this String, ignoring case considerations. see java.text.Collator#compare(String, String) since 1.2
public abstract com.sun.org.apache.xml.internal.utils.XMLString	concat(java.lang.String str) Concatenates the specified string to the end of this string. param str the String that is concatenated to the end of this String. return a string that represents the concatenation of this object's characters followed by the string argument's characters. exception java.lang.NullPointerException if str is null.
public abstract void	dispatchAsComment(org.xml.sax.ext.LexicalHandler lh) Directly call the comment method on the passed LexicalHandler for the string-value. param lh A non-null reference to a LexicalHandler. throws org.xml.sax.SAXException
public abstract void	dispatchCharactersEvents(org.xml.sax.ContentHandler ch) Directly call the characters method on the passed ContentHandler for the string-value. Multiple calls to the ContentHandler's characters methods may well occur for a single call to this method. param ch A non-null reference to a ContentHandler. throws org.xml.sax.SAXException
public abstract boolean	endsWith(java.lang.String suffix) Tests if this string ends with the specified suffix. param suffix the suffix. return true if the character sequence represented by the argument is a suffix of the character sequence represented by this object; false otherwise. Note that the result will be true if the argument is the empty string or is equal to this String object as determined by the {@link #equals(Object)} method. exception java.lang.NullPointerException if suffix is null.
public abstract boolean	equals(com.sun.org.apache.xml.internal.utils.XMLString anObject) Compares this string to the specified object. The result is true if and only if the argument is not null and is a String object that represents the same sequence of characters as this object. param anObject the object to compare this String against. return true if the String are equal; false otherwise. see java.lang.String#compareTo(java.lang.String) see java.lang.String#equalsIgnoreCase(java.lang.String)
public abstract boolean	equals(java.lang.Object anObject) Compares this string to the specified object. The result is true if and only if the argument is not null and is a String object that represents the same sequence of characters as this object. param anObject the object to compare this String against. return true if the String are equal; false otherwise. see java.lang.String#compareTo(java.lang.String) see java.lang.String#equalsIgnoreCase(java.lang.String)
public abstract boolean	equalsIgnoreCase(java.lang.String anotherString) Compares this String to another String, ignoring case considerations. Two strings are considered equal ignoring case if they are of the same length, and corresponding characters in the two strings are equal ignoring case. param anotherString the String to compare this String against. return true if the argument is not null and the Strings are equal, ignoring case; false otherwise. see #equals(Object) see java.lang.Character#toLowerCase(char) see java.lang.Character#toUpperCase(char)
public com.sun.org.apache.xml.internal.utils.XMLString	fixWhiteSpace(boolean trimHead, boolean trimTail, boolean doublePunctuationSpaces) Conditionally trim all leading and trailing whitespace in the specified String. All strings of white space are replaced by a single space character (#x20), except spaces after punctuation which receive double spaces if doublePunctuationSpaces is true. This function may be useful to a formatter, but to get first class results, the formatter should probably do it's own white space handling based on the semantics of the formatting object. param trimHead Trim leading whitespace? param trimTail Trim trailing whitespace? param doublePunctuationSpaces Use double spaces for punctuation? return The trimmed string.
public abstract void	getChars(int srcBegin, int srcEnd, char[] dst, int dstBegin) Copies characters from this string into the destination character array. param srcBegin index of the first character in the string to copy. param srcEnd index after the last character in the string to copy. param dst the destination array. param dstBegin the start offset in the destination array. exception IndexOutOfBoundsException If any of the following is true: srcBegin is negative. srcBegin is greater than srcEnd srcEnd is greater than the length of this string dstBegin is negative dstBegin+(srcEnd-srcBegin) is larger than dst.length exception NullPointerException if dst is null
public abstract boolean	hasString() Tell if this object contains a java String object. return true if this XMLString can return a string without creating one.
public abstract int	hashCode() Returns a hashcode for this string. The hashcode for a String object is computed as s[0]*31^(n-1) + s[1]*31^(n-2) + ... + s[n-1] using int arithmetic, where s[i] is the ith character of the string, n is the length of the string, and ^ indicates exponentiation. (The hash value of the empty string is zero.) return a hash code value for this object.
public abstract int	indexOf(int ch) Returns the index within this string of the first occurrence of the specified character. If a character with value ch occurs in the character sequence represented by this String object, then the index of the first such occurrence is returned -- that is, the smallest value k such that: this.charAt(k) == ch is true. If no such character occurs in this string, then -1 is returned. param ch a character. return the index of the first occurrence of the character in the character sequence represented by this object, or -1 if the character does not occur.
public abstract int	indexOf(int ch, int fromIndex) Returns the index within this string of the first occurrence of the specified character, starting the search at the specified index. If a character with value ch occurs in the character sequence represented by this String object at an index no smaller than fromIndex, then the index of the first such occurrence is returned--that is, the smallest value k such that: (this.charAt(k) == ch) && (k >= fromIndex) is true. If no such character occurs in this string at or after position fromIndex, then -1 is returned. There is no restriction on the value of fromIndex. If it is negative, it has the same effect as if it were zero: this entire string may be searched. If it is greater than the length of this string, it has the same effect as if it were equal to the length of this string: -1 is returned. param ch a character. param fromIndex the index to start the search from. return the index of the first occurrence of the character in the character sequence represented by this object that is greater than or equal to fromIndex, or -1 if the character does not occur.
public abstract int	indexOf(java.lang.String str) Returns the index within this string of the first occurrence of the specified substring. The integer returned is the smallest value k such that: this.startsWith(str, k) is true. param str any string. return if the string argument occurs as a substring within this object, then the index of the first character of the first such substring is returned; if it does not occur as a substring, -1 is returned. exception java.lang.NullPointerException if str is null.
public abstract int	indexOf(com.sun.org.apache.xml.internal.utils.XMLString str) Returns the index within this string of the first occurrence of the specified substring. The integer returned is the smallest value k such that: this.startsWith(str, k) is true. param str any string. return if the string argument occurs as a substring within this object, then the index of the first character of the first such substring is returned; if it does not occur as a substring, -1 is returned. exception java.lang.NullPointerException if str is null.
public abstract int	indexOf(java.lang.String str, int fromIndex) Returns the index within this string of the first occurrence of the specified substring, starting at the specified index. The integer returned is the smallest value k such that: this.startsWith(str, k) && (k >= fromIndex) is true. There is no restriction on the value of fromIndex. If it is negative, it has the same effect as if it were zero: this entire string may be searched. If it is greater than the length of this string, it has the same effect as if it were equal to the length of this string: -1 is returned. param str the substring to search for. param fromIndex the index to start the search from. return If the string argument occurs as a substring within this object at a starting index no smaller than fromIndex, then the index of the first character of the first such substring is returned. If it does not occur as a substring starting at fromIndex or beyond, -1 is returned. exception java.lang.NullPointerException if str is null
public abstract int	lastIndexOf(int ch) Returns the index within this string of the last occurrence of the specified character. That is, the index returned is the largest value k such that: this.charAt(k) == ch is true. The String is searched backwards starting at the last character. param ch a character. return the index of the last occurrence of the character in the character sequence represented by this object, or -1 if the character does not occur.
public abstract int	lastIndexOf(int ch, int fromIndex) Returns the index within this string of the last occurrence of the specified character, searching backward starting at the specified index. That is, the index returned is the largest value k such that: this.charAt(k) == ch) && (k <= fromIndex) is true. param ch a character. param fromIndex the index to start the search from. There is no restriction on the value of fromIndex. If it is greater than or equal to the length of this string, it has the same effect as if it were equal to one less than the length of this string: this entire string may be searched. If it is negative, it has the same effect as if it were -1: -1 is returned. return the index of the last occurrence of the character in the character sequence represented by this object that is less than or equal to fromIndex, or -1 if the character does not occur before that point.
public abstract int	lastIndexOf(java.lang.String str) Returns the index within this string of the rightmost occurrence of the specified substring. The rightmost empty string "" is considered to occur at the index value this.length(). The returned index is the largest value k such that this.startsWith(str, k) is true. param str the substring to search for. return if the string argument occurs one or more times as a substring within this object, then the index of the first character of the last such substring is returned. If it does not occur as a substring, -1 is returned. exception java.lang.NullPointerException if str is null.
public abstract int	lastIndexOf(java.lang.String str, int fromIndex) Returns the index within this string of the last occurrence of the specified substring. param str the substring to search for. param fromIndex the index to start the search from. There is no restriction on the value of fromIndex. If it is greater than the length of this string, it has the same effect as if it were equal to the length of this string: this entire string may be searched. If it is negative, it has the same effect as if it were -1: -1 is returned. return If the string argument occurs one or more times as a substring within this object at a starting index no greater than fromIndex, then the index of the first character of the last such substring is returned. If it does not occur as a substring starting at fromIndex or earlier, -1 is returned. exception java.lang.NullPointerException if str is null.

public abstract boolean	startsWith(java.lang.String prefix, int toffset) Tests if this string starts with the specified prefix beginning a specified index. param prefix the prefix. param toffset where to begin looking in the string. return true if the character sequence represented by the argument is a prefix of the substring of this object starting at index toffset; false otherwise. The result is false if toffset is negative or greater than the length of this String object; otherwise the result is the same as the result of the expression this.subString(toffset).startsWith(prefix) exception java.lang.NullPointerException if prefix is null.
public abstract boolean	startsWith(com.sun.org.apache.xml.internal.utils.XMLString prefix, int toffset) Tests if this string starts with the specified prefix beginning a specified index. param prefix the prefix. param toffset where to begin looking in the string. return true if the character sequence represented by the argument is a prefix of the substring of this object starting at index toffset; false otherwise. The result is false if toffset is negative or greater than the length of this String object; otherwise the result is the same as the result of the expression this.subString(toffset).startsWith(prefix) exception java.lang.NullPointerException if prefix is null.
public abstract boolean	startsWith(java.lang.String prefix) Tests if this string starts with the specified prefix. param prefix the prefix. return true if the character sequence represented by the argument is a prefix of the character sequence represented by this string; false otherwise. Note also that true will be returned if the argument is an empty string or is equal to this String object as determined by the {@link #equals(Object)} method. exception java.lang.NullPointerException if prefix is null. since JDK1. 0
public abstract boolean	startsWith(com.sun.org.apache.xml.internal.utils.XMLString prefix) Tests if this string starts with the specified prefix. param prefix the prefix. return true if the character sequence represented by the argument is a prefix of the character sequence represented by this string; false otherwise. Note also that true will be returned if the argument is an empty string or is equal to this String object as determined by the {@link #equals(Object)} method. exception java.lang.NullPointerException if prefix is null. since JDK1. 0
public abstract com.sun.org.apache.xml.internal.utils.XMLString	substring(int beginIndex) Returns a new string that is a substring of this string. The substring begins with the character at the specified index and extends to the end of this string. Examples: "unhappy".substring(2) returns "happy" "Harbison".substring(3) returns "bison" "emptiness".substring(9) returns "" (an empty string) param beginIndex the beginning index, inclusive. return the specified substring. exception IndexOutOfBoundsException if beginIndex is negative or larger than the length of this String object.
public abstract com.sun.org.apache.xml.internal.utils.XMLString	substring(int beginIndex, int endIndex) Returns a new string that is a substring of this string. The substring begins at the specified beginIndex and extends to the character at index endIndex - 1. Thus the length of the substring is endIndex-beginIndex. param beginIndex the beginning index, inclusive. param endIndex the ending index, exclusive. return the specified substring. exception IndexOutOfBoundsException if the beginIndex is negative, or endIndex is larger than the length of this String object, or beginIndex is larger than endIndex.
public double	toDouble() Convert a string to a double -- Allowed input is in fixed notation ddd.fff. return A double value representation of the string, or return Double.NaN if the string can not be converted.
public abstract com.sun.org.apache.xml.internal.utils.XMLString	toLowerCase(java.util.Locale locale) Converts all of the characters in this String to lower case using the rules of the given Locale. param locale use the case transformation rules for this locale return the String, converted to lowercase. see java.lang.Character#toLowerCase(char) see java.lang.String#toUpperCase(Locale)
public abstract com.sun.org.apache.xml.internal.utils.XMLString	toLowerCase() Converts all of the characters in this String to lower case using the rules of the default locale, which is returned by Locale.getDefault. return the string, converted to lowercase. see java.lang.Character#toLowerCase(char) see java.lang.String#toLowerCase(Locale)
public abstract java.lang.String	toString() This object (which is already a string!) is itself returned. return the string itself.
public abstract com.sun.org.apache.xml.internal.utils.XMLString	toUpperCase(java.util.Locale locale) Converts all of the characters in this String to upper case using the rules of the given locale. param locale use the case transformation rules for this locale return the String, converted to uppercase. see java.lang.Character#toUpperCase(char) see java.lang.String#toLowerCase(Locale)
public abstract com.sun.org.apache.xml.internal.utils.XMLString	toUpperCase() Converts all of the characters in this String to upper case using the rules of the default locale, which is returned by Locale.getDefault. If no character in this string has a different uppercase version, based on calling the toUpperCase method defined by Character, then the original string is returned. Otherwise, this method creates a new String object representing a character sequence identical in length to the character sequence represented by this String object and with every character equal to the result of applying the method Character.toUpperCase to the corresponding character of this String object. Examples: "Fahrvergngen".toUpperCase() returns "FAHRVERGNGEN" "Visit Ljubinje!".toUpperCase() returns "VISIT LJUBINJE!" return the string, converted to uppercase. see java.lang.Character#toUpperCase(char) see java.lang.String#toUpperCase(Locale)
public abstract com.sun.org.apache.xml.internal.utils.XMLString	trim() Removes white space from both ends of this string. If this String object represents an empty character sequence, or the first and last characters of character sequence represented by this String object both have codes greater than '\u0020' (the space character), then a reference to this String object is returned. Otherwise, if there is no character with a code greater than '\u0020' in the string, then a new String object representing an empty string is created and returned. Otherwise, let k be the index of the first character in the string whose code is greater than '\u0020', and let m be the index of the last character in the string whose code is greater than '\u0020'. A new String object is created, representing the substring of this string that begins with the character at index k and ends with the character at index m-that is, the result of this.substring(k, m+1). This method may be used to trim {@link Character#isSpace(char) whitespace} from the beginning and end of a string; in fact, it trims all ASCII control characters as well. return this string, with white space removed from the front and end.
