int	m_start The start position in the fsb.
int	m_length The length of the string.
protected String	m_strCache

Constructors Summary
public XStringForChars(char[] val, int start, int length) Construct a XNodeSet object. param val FastStringBuffer object this will wrap, must be non-null. param start The start position in the array. param length The number of characters to read from the array. super(val); m_start = start; m_length = length; if(null == val) throw new IllegalArgumentException( XSLMessages.createXPATHMessage(XPATHErrorResources.ER_FASTSTRINGBUFFER_CANNOT_BE_NULL, null)); //"The FastStringBuffer argument can not be null!!");
private XStringForChars(String val) Construct a XNodeSet object. param val String object this will wrap. super(val); throw new IllegalArgumentException( XSLMessages.createXPATHMessage(XPATHErrorResources.ER_XSTRINGFORCHARS_CANNOT_TAKE_STRING, null)); //"XStringForChars can not take a string for an argument!");

Methods Summary
public void	appendToFsb(com.sun.org.apache.xml.internal.utils.FastStringBuffer fsb) Cast result object to a string. return The string this wraps or the empty string if null fsb.append((char[])m_obj, m_start, m_length);
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. 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. return ((char[])m_obj)[index+m_start];
public 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 lh.comment((char[])m_obj, m_start, m_length);
public 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 ch.characters((char[])m_obj, m_start, m_length);
public com.sun.org.apache.xml.internal.utils.FastStringBuffer	fsb() Cast result object to a string. return The string this wraps or the empty string if null throw new RuntimeException(XSLMessages.createXPATHMessage(XPATHErrorResources.ER_FSB_NOT_SUPPORTED_XSTRINGFORCHARS, null)); //"fsb() not supported for XStringForChars!");
public 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 System.arraycopy((char[])m_obj, m_start+srcBegin, dst, dstBegin, srcEnd);
public boolean	hasString() Tell if this object contains a java String object. return true if this XMLString can return a string without creating one. return (null != m_strCache);
public int	length() Returns the length of this string. return the length of the sequence of characters represented by this object. return m_length;
public java.lang.Object	object() Since this object is incomplete without the length and the offset, we have to convert to a string when this function is called. return The java String representation of this object. return str();
public java.lang.String	str() Cast result object to a string. return The string this wraps or the empty string if null if(null == m_strCache) m_strCache = new String((char[])m_obj, m_start, m_length); return m_strCache;
