A charset is named mapping between sequences of sixteen-bit Unicode * characters and sequences of bytes, in the sense defined in RFC 2278. A * decoder is an engine which transforms bytes in a specific charset into * characters, and an encoder is an engine which transforms characters into * bytes. Encoders and decoders operate on byte and character buffers. They are * collectively referred to as coders. * *
The {@link java.nio.charset.Charset} class defines methods for creating * coders for a given charset and for retrieving the various names associated with * a charset. It also defines static methods for testing whether a particular * charset is supported, for locating charset instances by name, and for * constructing a map that contains every charset for which support is available * in the current Java virtual machine. * *
Most users will not use these classes directly; instead they will use the * existing charset-related constructors and methods in the {@link * java.lang.String} class, together with the existing {@link * java.io.InputStreamReader} and {@link java.io.OutputStreamWriter} classes, all * of whose implementations have been reworked to make use of the charset * facilities defined in this package. A small number of changes have been made * to the {@link java.io.InputStreamReader} and {@link java.io.OutputStreamWriter} * classes in order to allow explicit charset objects to be specified in the * construction of instances of those classes. * *
Support for new charsets can be made available via the interface defined in * the {@link java.nio.charset.spi.CharsetProvider} class in the {@link * java.nio.charset.spi} package. * *
Unless otherwise noted, passing a null argument to a constructor * or method in any class or interface in this package will cause a {@link * java.lang.NullPointerException NullPointerException} to be thrown. * * * @since 1.4 * @author Mark Reinhold * @author JSR-51 Expert Group */
