Class CharsetDecoderICU
public abstract
class
CharsetDecoderICU
extends CharsetDecoder
An abstract class that provides framework methods of decoding operations for concrete
subclasses.
In the future this class will contain API that will implement converter sematics of ICU4C.
UNKNOWN: ICU 3.6 This API might change or be removed in a future release.
Method Summary |
protected CoderResult | decodeLoop(ByteBuffer in, CharBuffer out)
Decodes one or more bytes. |
protected CoderResult | implFlush(CharBuffer out)
Flushes any characters saved in the converter's internal buffer and
resets the converter. |
protected void | implOnMalformedInput(CodingErrorAction newAction)
Sets the action to be taken if an illegal sequence is encountered |
protected void | implOnUnmappableCharacter(CodingErrorAction newAction)
Sets the action to be taken if an illegal sequence is encountered |
protected void | implReset()
Resets the to Unicode mode of converter |
protected CoderResult decodeLoop(ByteBuffer in, CharBuffer out)
Decodes one or more bytes. The default behaviour of the converter
is stop and report if an error in input stream is encountered.
To set different behaviour use @see CharsetDecoder.onMalformedInput()
This method allows a buffer by buffer conversion of a data stream.
The state of the conversion is saved between calls to convert.
Among other things, this means multibyte input sequences can be
split between calls. If a call to convert results in an Error, the
conversion may be continued by calling convert again with suitably
modified parameters.All conversions should be finished with a call to
the flush method.
Parameters: in buffer to decode out buffer to populate with decoded result
Returns: Result of decoding action. Returns CoderResult.UNDERFLOW if the decoding
action succeeds or more input is needed for completing the decoding action.
UNKNOWN: ICU 3.6
protected final CoderResult implFlush(CharBuffer out)
Flushes any characters saved in the converter's internal buffer and
resets the converter.
Parameters: out action to be taken
Returns: result of flushing action and completes the decoding all input.
Returns CoderResult.UNDERFLOW if the action succeeds.
UNKNOWN: ICU 3.6
protected final void implOnMalformedInput(CodingErrorAction newAction)
Sets the action to be taken if an illegal sequence is encountered
Parameters: newAction action to be taken
Throws: IllegalArgumentException
UNKNOWN: ICU 3.6
protected final void implOnUnmappableCharacter(CodingErrorAction newAction)
Sets the action to be taken if an illegal sequence is encountered
Parameters: newAction action to be taken
Throws: IllegalArgumentException
UNKNOWN: ICU 3.6
protected void implReset()
Resets the to Unicode mode of converter
UNKNOWN: ICU 3.6
