* This class allows an implementor to provide additional character sets. The
|
|
* subclass must have a nullary constructor, and be attached to charset
|
|
* implementation classes. These extensions are loaded via the context class
|
|
* loader. To provide the charset extension, all files named
|
|
* <code>META-INF/services/java.nio.charset.spi.CharsetProvider</code> are
|
|
* read from the classpath. Each one should be a UTF-8 encoded list of
|
|
* fully-qualified names of concrete subclasses of this class; whitespace is
|
|
* ignored, and '#' starts comments. Duplicates are ignored. The
|
|
* implementations must be accessible to the classloader that requests them.
