| * <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 <tt>{@link |
| * java.nio.charset.spi}</tt> package. |
| * |
| * <p> Unless otherwise noted, passing a <tt>null</tt> 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. |
