Class CharacterUtil

java.lang.Object

jsimple.util.CharacterUtil

public final class CharacterUtil
extends java.lang.Object

The wrapper for the primitive type char. This class also provides a number of utility methods for working with characters.

Character data is based upon the Unicode Standard, 4.0. The Unicode specification, character tables and other information are available at http://www.unicode.org/.

Unicode characters are referred to as code points. The range of valid code points is U+0000 to U+10FFFF. The Basic Multilingual Plane (BMP) is the code point range U+0000 to U+FFFF. Characters above the BMP are referred to as Supplementary Characters. On the Java platform, UTF-16 encoding and char pairs are used to represent code points in the supplementary range. A pair of char values that represent a supplementary character are made up of a high surrogate with a value range of 0xD800 to 0xDBFF and a low surrogate with a value range of 0xDC00 to 0xDFFF.

On the Java platform a char value represents either a single BMP code point or a UTF-16 unit that's part of a surrogate pair. The int type is used to represent all Unicode code points.

Parameters:

c - the character to reverse.

Returns:

the character with reordered bytes.

toString
