OutputStreamWriter

public OutputStreamWriter(OutputStream out,
 java.nio.charset.CharsetEncoder enc)

Enabled: Create an OutputStreamWriter that uses the given charset encoder.

Parameters:

out - An OutputStream

enc - A charset encoder

getEncoding

public String getEncoding()

Enabled: Return the name of the character encoding being used by this stream.

If the encoding has an historical name then that name is returned; otherwise the encoding's canonical name is returned.

If this instance was created with the OutputStreamWriter(OutputStream, String) constructor then the returned name, being unique for the encoding, may differ from the name passed to the constructor. This method may return null if the stream has been closed.

Returns:

The historical name of this encoding, or possibly null if the stream has been closed
