public class Charsets
extends java.lang.Object

Charsets required of every implementation of the Java platform. From the Java documentation Standard charsets:

Every implementation of the Java platform is required to support the following character encodings. Consult the release documentation for your implementation to see if any other encodings are supported. Consult the release documentation for your implementation to see if any other encodings are supported.

US-ASCII

Seven-bit ASCII, a.k.a. ISO646-US, a.k.a. the Basic Latin block of the Unicode character set.

ISO-8859-1

ISO Latin Alphabet No. 1, a.k.a. ISO-LATIN-1.

UTF-8

Eight-bit Unicode Transformation Format.

UTF-16BE

Sixteen-bit Unicode Transformation Format, big-endian byte order.

UTF-16LE

Sixteen-bit Unicode Transformation Format, little-endian byte order.

UTF-16

Sixteen-bit Unicode Transformation Format, byte order specified by a mandatory initial byte-order mark (either order accepted on input, big-endian used on output.)

This class best belongs in the Commons Lang or IO project. Even if a similar class is defined in another Commons component, it is not foreseen that Commons Compress would be made to depend on another Commons component.

Method Detail

toCharset

public static java.nio.charset.Charset toCharset(java.nio.charset.Charset charset)

Returns the given Charset or the default Charset if the given Charset is null.

Parameters:

charset - A charset or null.

Returns:

the given Charset or the default Charset if the given Charset is null

toCharset

public static java.nio.charset.Charset toCharset(java.lang.String charset)

Returns a Charset for the named charset. If the name is null, return the default Charset.

Parameters:

charset - The name of the requested charset, may be null.

Returns:

a Charset for the named charset

Throws:

java.nio.charset.UnsupportedCharsetException - If the named charset is unavailable

java.nio.charset.IllegalCharsetNameException - If the given charset name is illegal
