void |
EWAHCompressedBitmap.andNotToContainer(EWAHCompressedBitmap a,
BitmapStorage container)
Returns a new compressed bitmap containing the bitwise AND NOT values of
the current bitmap with some other bitmap.
|
void |
EWAHCompressedBitmap.andToContainer(EWAHCompressedBitmap a,
BitmapStorage container)
Computes new compressed bitmap containing the bitwise AND values of the
current bitmap with some other bitmap.
|
static void |
EWAHCompressedBitmap.andWithContainer(BitmapStorage container,
EWAHCompressedBitmap... bitmaps)
For internal use.
|
void |
IteratingBufferedRunningLengthWord.discharge(BitmapStorage container)

|
void |
IteratingBufferedRunningLengthWord.dischargeAsEmpty(BitmapStorage container)
Write out the remain words, transforming them to zeroes.
|
long |
IteratingBufferedRunningLengthWord.dischargeNegated(BitmapStorage container,
long max)

|
static void |
EWAHCompressedBitmap.orWithContainer(BitmapStorage container,
EWAHCompressedBitmap... bitmaps)
For internal use.
|
void |
IteratingBufferedRunningLengthWord.writeLiteralWords(int numWords,
BitmapStorage container)
