| Methods Summary |
|---|
| public boolean | bool()Cast result object to a boolean.
return str().length() > 0;
|
| public void | callVisitors(com.sun.org.apache.xpath.internal.ExpressionOwner owner, com.sun.org.apache.xpath.internal.XPathVisitor visitor)
visitor.visitStringLiteral(owner, this);
|
| public 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.
return str().charAt(index);
|
| public int | compareTo(com.sun.org.apache.xml.internal.utils.XMLString xstr)Compares two strings lexicographically.
int len1 = this.length();
int len2 = xstr.length();
int n = Math.min(len1, len2);
int i = 0;
int j = 0;
while (n-- != 0)

|
| public 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.
// %REVIEW% Like it says, @since 1.2. Doesn't exist in earlier
// versions of Java, hence we can't yet shell out to it. We can implement
// it as character-by-character compare, but doing so efficiently
// is likely to be (ahem) interesting.
//
// However, since nobody is actually _using_ this method yet:
// return str().compareToIgnoreCase(str.toString());

null and is a String object that represents
the same sequence of characters as this object.

|
| public 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.

|
| 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.

array.

For diagnostic purposes.

|
| public boolean | hasString()Tell if this object contains a java String object.
return true;
|
| public 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.

|
| public 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.
return str().indexOf(ch);
|
| public 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.
return str().indexOf(ch, fromIndex);

specified substring. The integer returned is the smallest value
k such that:

|
| public int | indexOf(com.sun.org.apache.xml.internal.utils.XMLString str)Returns the index within this string of the first occurrence of the

is true.
return str().indexOf(str.toString());
|
| public 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:

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.

of whitespace. Refer to
the definition of S for details.
return XMLCharacterRecognizer.isWhiteSpace(ch); // Take the easy way out for now.

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.
return str().lastIndexOf(ch);
|
| public 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

is true.
return str().lastIndexOf(ch, fromIndex);
|
| public int | lastIndexOf(java.lang.String str)Returns the index within this string of the rightmost occurrence

return (null != m_obj) ? ((String) m_obj) : "";
|
| public com.sun.org.apache.xml.internal.utils.XMLString | substring(int beginIndex)Returns a new string that is a substring of this string. The

| public 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.
return new XString(str().toLowerCase(locale));
|
| public 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.

|
| public 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.
return new XString(str().toUpperCase(locale));
|
| public 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:
"Fahrvergnügen".toUpperCase() returns "FAHRVERGNÜGEN"
"Visit Ljubinje!".toUpperCase() returns "VISIT LJUBINJE!"
return new XString(str().toUpperCase());
|
| public com.sun.org.apache.xml.internal.utils.XMLString | trim()Removes white space from both ends of this string.

|
| public com.sun.org.apache.xml.internal.utils.XMLString | xstr()Cast result object to a string.
return this;
