Method Details

implReset

protected void implReset()

Description copied from class: CharsetEncoderICU

Resets the from Unicode mode of converter

Overrides:

implReset in class CharsetEncoderICU

encodeLoop

protected CoderResult encodeLoop(CharBuffer source,
 ByteBuffer target,
 IntBuffer offsets,
 boolean flush)

Specified by:

encodeLoop in class CharsetEncoderICU

fromUChar32

int fromUChar32(int c,
 int[] pValue,
 boolean isUseFallback)

continueMatchFromU

private CoderResult continueMatchFromU(CharBuffer source,
 ByteBuffer target,
 IntBuffer offsets,
 boolean flush,
 int srcIndex)

matchFromU

private int matchFromU(int firstCP,
 char[] preArray,
 int preArrayBegin,
 int preLength,
 CharBuffer source,
 int[] pMatchValue,
 boolean isUseFallback,
 boolean flush)

Parameters:

firstCP - the first code point before all the other UChars

preLength - length of pre, >=0

pMatchValue - [out] output result value for the match from the data structure

flush - true if the end of the input stream is reached

cx - pointer to extension data; if NULL, returns 0

pre - UChars that must match; !initialMatch: partial match with them

src - UChars that can be used to complete a match

srcLength - length of src, >=0

useFallback - "use fallback" flag, usually from cnv->useFallback

Returns:

>1: matched, return value=total match length (number of input units matched) 1: matched, no mapping but request for (only for the first code point) 0: no match invalid input: '<'0: partial match, return value=negative total match length (partial matches are never returned for flush==true) (partial matches are never returned as being longer than UCNV_EXT_MAX_UCHARS) the matchLength is 2 if only firstCP matched, and >2 if firstCP and further code units matched

simpleMatchFromU

private int simpleMatchFromU(int cp,
 int[] pValue,
 boolean isUseFallback)

writeFromU

private CoderResult writeFromU(int value,

fromU

private int fromU(int cp,
 CharBuffer source,
 ByteBuffer target,
 IntBuffer offsets,
 int sourceIndex,
 int length,
 boolean flush,
 CoderResult[] cr)

Returns:

if(U_FAILURE) return the code point for cnv->fromUChar32 else return 0 after output has been written to the target

initialMatchFromU

private boolean initialMatchFromU(int cp,

cbFromUWriteSub

protected CoderResult cbFromUWriteSub(CharsetEncoderICU encoder,
 CharBuffer source,
 ByteBuffer target,
 IntBuffer offsets)

Overrides super class method

Overrides:

cbFromUWriteSub in class CharsetEncoderICU

Parameters:

encoder -

source -

target -

offsets -

Returns:

implReplaceWith

protected void implReplaceWith(byte[] replacement)

Gets called whenever CharsetEncoder.replaceWith gets called. allowReplacementChanges only allows subChar and subChar1 to be modified outside construction (since replaceWith is called once during construction).

Overrides:

implReplaceWith in class CharsetEncoder

Parameters:

replacement - The replacement for subchar.
