public char charAt(int index)
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.charAt in interface XMLStringcharAt in class XStringindex - the index of the character.0.java.lang.IndexOutOfBoundsException - if the index
argument is negative or not less than the length of this
string.public void getChars(int srcBegin,
int srcEnd,
char[] dst,
int dstBegin)
getChars in interface XMLStringgetChars in class XStringsrcBegin - index of the first character in the string
to copy.srcEnd - index after the last character in the string
to copy.dst - the destination array.dstBegin - the start offset in the destination array.java.lang.IndexOutOfBoundsException - If any of the following
is true:
srcBegin is negative.
srcBegin is greater than srcEnd

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.public boolean equals(XObject obj2)

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.public boolean equalsIgnoreCase(java.lang.String anotherString)
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.equalsIgnoreCase in interface XMLStringequalsIgnoreCase in class XStringanotherString - the String to compare this
String against.true if the argument is not null
and the Strings are equal,
ignoring case; false otherwise.equals(Object),
Character.toLowerCase(char),
Character.toUpperCase(char)public int compareTo(XMLString xstr)
compareTo in interface XMLStringcompareTo in class XStringxstr - the String to be compared.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.java.lang.NullPointerException - if anotherString
is null.public int compareToIgnoreCase(XMLString xstr)
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.
compareToIgnoreCase in interface XMLStringcompareToIgnoreCase in class XStringxstr - the String to be compared.Collator.compare(String, String)public int hashCode()
String object is computed as
usings[0]*31^(n-1) + s[1]*31^(n-2) + ... + s[n-1]
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.)public boolean startsWith(XMLString prefix, int toffset)
startsWith in interface XMLStringstartsWith in class XStringprefix - the prefix.toffset - where to begin looking in the string.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)
java.lang.NullPointerException - if prefix is
null.public boolean startsWith(XMLString prefix)
startsWith in interface XMLStringstartsWith in class XStringprefix - the prefix.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
equals(Object) method.java.lang.NullPointerException - if prefix is
null.public int indexOf(int ch)
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:
isthis.charAt(k) == ch
true. If no such character occurs in this string,
then -1 is returned.public int indexOf(int ch,
int fromIndex)
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:
is true. If no such character occurs in this string at or after position(this.charAt(k) == ch) && (k >= fromIndex)
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.
indexOf in interface XMLStringindexOf in class XStringch - a character.fromIndex - the index to start the search from.fromIndex, or -1
if the character does not occur.public XMLString substring(int beginIndex)
Examples:
"unhappy".substring(2) returns "happy" "Harbison".substring(3) returns "bison" "emptiness".substring(9) returns "" (an empty string)
public XMLString substring(int beginIndex, int endIndex)
beginIndex and
extends to the character at index endIndex - 1.
Thus the length of the substring is endIndex-beginIndex.substring in interface XMLStringsubstring in class XStringbeginIndex - the beginning index, inclusive.endIndex - the ending index, exclusive.java.lang.IndexOutOfBoundsException - if the
beginIndex is negative, or
endIndex is larger than the length of
this String object, or
beginIndex is larger than
endIndex.public XMLString concat(java.lang.String str)
concat in interface XMLStringconcat in class XStringstr - the String that is concatenated to the end
of this String.java.lang.NullPointerException - if str is
null.public XMLString trim()
public XMLString fixWhiteSpace(boolean trimHead, boolean trimTail, boolean doublePunctuationSpaces)
fixWhiteSpace in interface XMLStringfixWhiteSpace in class XStringtrimHead - Trim leading whitespace?trimTail - Trim trailing whitespace?doublePunctuationSpaces - Use double spaces for punctuation?public double toDouble()
