Conditionally trim all leading and trailing whitespace in the specified String.

public int lastIndexOf(String str, int fromIndex) { return m_str.lastIndexOf(str, fromIndex); }
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)
Params:
  • beginIndex – the beginning index, inclusive.
Throws:
Returns: the specified substring.

public XMLString substring(int beginIndex) { return new XMLStringDefault(m_str.substring(beginIndex)); }
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.
Params:
  • beginIndex – the beginning index, inclusive.
  • endIndex – the ending index, exclusive.
Throws:
  • IndexOutOfBoundsException – if the beginIndex is negative, or endIndex is larger than the length of this String object, or beginIndex is larger than endIndex.
Returns: the specified substring.
/** * Returns a new string that is a substring of this string.

Concatenates the specified string to the end of this string.
Params:
  • str – the String that is concatenated to the end of this String.
Throws:
Returns: a string that represents the concatenation of this object's characters followed by the string argument's characters.
/** * Concatenates the specified string to the end of this string. * * @param str the <code>String</code> that is concatenated to the end * of this <code>String</code>. * @return a string that represents the concatenation of this object's * characters followed by the string argument's characters. * @exception java.lang.NullPointerException if <code>str</code> is * <code>null</code>. */

Converts all of the characters in this String to lower case using the rules of the given Locale.
Params:
  • locale – use the case transformation rules for this locale
See Also:
Returns:the String, converted to lowercase.
/** * Converts all of the characters in this <code>String</code> to lower * case using the rules of the given <code>Locale</code>. * * @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 XMLString toLowerCase(Locale locale) { return new XMLStringDefault(m_str.toLowerCase(locale)); }
Converts all of the characters in this String to lower case using the rules of the default locale, which is returned by Locale.getDefault.

See Also:
Returns: the string, converted to lowercase.
/** * Converts all of the characters in this <code>String</code> to lower * case using the rules of the default locale, which is returned * by <code>Locale.getDefault</code>. * <p> * * @return the string, converted to lowercase. * @see java.lang.Character#toLowerCase(char) * @see java.lang.String#toLowerCase(Locale) */
public XMLString toLowerCase() { return new XMLStringDefault(m_str.toLowerCase()); }
Converts all of the characters in this String to upper case using the rules of the given locale.
Params:
  • locale – use the case transformation rules for this locale
See Also:
Returns:the String, converted to uppercase.
/** * Converts all of the characters in this <code>String</code> 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 XMLString toUpperCase(Locale locale) { return new XMLStringDefault(m_str.toUpperCase(locale)); }
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!"
See Also:
Returns: the string, converted to uppercase.

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(km+1).

This method may be used to trim whitespace from the beginning and end of a string; in fact, it trims all ASCII control characters as well.

Returns: this string, with white space removed from the front and end.
/** * Removes white space from both ends of this string. * <p> * If this <code>String</code> object represents an empty character * sequence, or the first and last characters of character sequence * represented by this <code>String</code> object both have codes * greater than <code>'&#92;u0020'</code> (the space character), then a * reference to this <code>String</code> object is returned. * <p> * Otherwise, if there is no character with a code greater than * <code>'&#92;u0020'</code> in the string, then a new * <code>String</code> object representing an empty string is created * and returned. * <p> * Otherwise, let <i>k</i> be the index of the first character in the * string whose code is greater than <code>'&#92;u0020'</code>, and let * <i>m</i> be the index of the last character in the string whose code * is greater than <code>'&#92;u0020'</code>.

Returns: the string itself.

Returns:A double value representation of the string, or return Double.NaN if the string can not be converted.
