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 { // Protected Constructors protected CharsetEncoder (Charset cs , float averageBytesPerChar , float maxBytesPerChar ); protected CharsetEncoder (Charset cs , float averageBytesPerChar , float maxBytesPerChar , byte[ ] replacement ); // Public Instance Methods public final float averageBytesPerChar ( ); public boolean canEncode (CharSequence cs ); public boolean canEncode (char c ); public final Charset charset ( ); public final java.nio.ByteBuffer encode (java.nio.CharBuffer in ) throws CharacterCodingException; public final CoderResult encode (java.nio.CharBuffer in , java.nio.ByteBuffer out , boolean endOfInput ); public final CoderResult flush (java.nio.ByteBuffer out ); public boolean isLegalReplacement (byte[ ] repl ); public CodingErrorAction malformedInputAction ( ); public final float maxBytesPerChar ( ); public final CharsetEncoder onMalformedInput (CodingErrorAction newAction ); public final CharsetEncoder onUnmappableCharacter (CodingErrorAction newAction ); public final byte[ ] replacement ( ); public final CharsetEncoder replaceWith (byte[ ] newReplacement ); public final CharsetEncoder reset ( ); public CodingErrorAction unmappableCharacterAction ( ); // Protected Instance Methods protected abstract CoderResult encodeLoop (java.nio.CharBuffer in , java.nio.ByteBuffer out ); protected CoderResult implFlush (java.nio.ByteBuffer out ); protected void implOnMalformedInput (CodingErrorAction newAction ); empty protected void implOnUnmappableCharacter (CodingErrorAction newAction ); empty protected void implReplaceWith (byte[ ] newReplacement ); empty protected void implReset ( ); empty } Passed Tojava.io.OutputStreamWriter.OutputStreamWriter( ) , java.nio.channels.Channels.newWriter( ) Returned ByCharset.newEncoder( ) |
