Class CharEncoderReader

java.lang.Object

java.io.Reader

com.ziesemer.utils.codec.io.CharEncoderReader

All Implemented Interfaces:

Closeable, AutoCloseable, Readable

public class CharEncoderReader
extends Reader

Reads encoded characters from raw bytes. Counter-part to CharDecoderInputStream. This is a pull-interface; CharEncoderOutputStream is the equivalent push-interface.

Can be adapted to read characters to the consumer (instead of raw bytes) by wrapping in a InputStreamReader.
