Examples of com.caucho.vfs.i18n.EncodingWriter

com.caucho.vfs.i18n.EncodingWriter
Abstract class for a character-to-byte encoding writer.
Implementations need to implement create and write() at minimum. Efficient implementations will also implement the write into a buffer.
Implementations should not buffer the bytes.
