Examples of java.nio.charset.CharsetDecoder.decode()

java.nio.charset.CharsetDecoder.decode()
This is a facade method for decoding operation.
This method decodes the remaning byte sequence of the given byte buffer into a new character buffer. This method performs a complete decoding operation, resets at first, then decodes, and flushes at last.

This method should not be invoked if another decode operation is ongoing.
@param in the input buffer @return a new CharBuffer containing the the charactersproduced by this decoding operation. The buffer's limit will be the position of last character in buffer, and the position will be zero @throws IllegalStateException if another decoding operation is ongoing @throws MalformedInputException if illegal input byte sequence for this charset encountered, and the action for malformed error is {@link CodingErrorAction#REPORT CodingErrorAction.REPORT} @throws UnmappableCharacterException if legal but unmappable input byte sequence for this charset encountered, and the action for unmappable character error is {@link CodingErrorAction#REPORT CodingErrorAction.REPORT}. Unmappable means the byte sequence at the input buffer's current postion cannot be mapped to a Unicode character sequence. @throws CharacterCodingException if other exception happened during the decode operation
