hashCode in class java.lang.Object

indexOf

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.

Specified by:

indexOf in interface XMLString

Parameters:

ch - a character.

Returns:

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.

indexOf

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.

Specified by:

indexOf in interface XMLString

Parameters:

ch - a character.

fromIndex - the index to start the search from.

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.

lastIndexOf

public 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:

is true. The String is searched backwards starting at the last character.

Specified by:

lastIndexOf in interface XMLString

Parameters:

ch - a character.

Returns:

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.

is true.

Specified by:

lastIndexOf in interface XMLString

Parameters:

ch - a character.

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.

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.

toUpperCase

public 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!"
 

Specified by:

                               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.

Specified by:

fixWhiteSpace in interface XMLString

Parameters:

trimHead - Trim leading whitespace?

trimTail - Trim trailing whitespace?

doublePunctuationSpaces - Use double spaces for punctuation?

Returns:

The trimmed string.
