| * <p> A <i>charset</i> is named mapping between sequences of | |
| * sixteen-bit Unicode characters and sequences of bytes, in the sense | |
| * defined in <a | |
| * href="http://www.ietf.org/rfc/rfc2278.txt"><i>RFC 2278</i></a>. | |
| * A <i>decoder</i> is an engine which transforms bytes in a specific | |
| * charset into characters, and an <i>encoder</i> is an engine which | |
| * transforms characters into bytes. Encoders and decoders operate on | |
| * byte and character buffers. They are collectively referred to as | |
| * <i>coders</i>. | |
| * | |
| * <p> 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. | |
| * | |
| * <p> 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. | |
| * | |
| * <p> 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. | |
| * | |
| * <p> Unless otherwise noted, passing a {@code 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. | |
