Class CharacterRedirects

java.lang.Object
  org.jboss.lang.CharacterRedirects

public final class CharacterRedirects
extends Object

Contains methods added to java.lang.Character in 1.5. Strings in 1.4 don't know about surrogate pairs and the difference between code points and chars, so for now just treat characters as if they were code points.

public CharacterRedirects()

Method Detail

isHighSurrogate

public static boolean isHighSurrogate(char ch)

isLowSurrogate

public static boolean isLowSurrogate(char ch)

isSurrogatePair

public static boolean isSurrogatePair(char high,
                                      char low)

charCount

public static int charCount(int codePoint)

toCodePoint

public static int toCodePoint(char high,
                              char low)

Get the code point for the given high+low surrogate. Since java 1.4 doesn't support surrogates, the result of this method is always undefined. Just return '?'.

Parameters:

high - the high surrogate

low - the low surrogate

Returns:

the code point

codePointAt

codePointBefore

public static int codePointBefore(CharSequence seq,
                                  int index)

codePointBefore
