/**
* Defines charsets, decoders, and encoders, for translating between bytes and
* Unicode characters.
*
*
* Class name
Description
{@link java.nio.charset.Charset}
* A named mapping between characters
and bytes {@link java.nio.charset.CharsetDecoder}
* Decodes bytes into characters {@link java.nio.charset.CharsetEncoder}
* Encodes characters into bytes {@link java.nio.charset.CoderResult}
* Describes coder results {@link java.nio.charset.CodingErrorAction}
* Describes actions to take when
coding errors are detected
*
* 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.
