| CharsetEncoder | java.nio.charset |
A CharsetEncoder is an
"encoding engine" that converts a
sequence of characters into a sequence of bytes using some character
encoding. Obtain a CharsetEncoder with the
newEncoder( ) method of the
Charset that represents the desired encoding.A CharsetEncoder works like a
CharsetDecoder in reverse. Use the
encode( )
method to encode characters read from a CharBuffer
into bytes stored in a ByteBuffer. Please see
CharsetDecoder, which is documented in detail.public abstract class CharsetEncoder {
