Class OutputStreamWriter

java.lang.Object
java.io.Writer
java.io.OutputStreamWriter
All Implemented Interfaces:
java.io.Closeable, java.io.Flushable, Appendable, AutoCloseable
public class OutputStreamWriter extends java.io.Writer
An OutputStreamWriter is a bridge from character streams to byte streams: Characters written to it are translated into bytes. The encoding that it uses may be specified by name, or the platform's default encoding may be accepted. Each invocation of a write() method causes the encoding converter to be invoked on the given character(s). The resulting bytes are accumulated in a buffer before being written to the underlying output stream. The size of this buffer may be specified, but by default it is large enough for most purposes. Note that the characters passed to the write() methods are not buffered. Since: CLDC 1.0 See Also:Writer, UnsupportedEncodingException
