public interface CBlkWTDataSrc extends ForwWTDataProps
This class is the source of data for the quantizer. See the 'Quantizer' class.
Note that no more of one object may request data, otherwise one object would get some of the data and another one another part, in no defined manner.

int |
getDataType(int t,
int c)
Return the data type of this CBlkWTDataSrc for the given
component in the current tile.
|
int |
getFixedPoint(int n)
Returns the position of the fixed point in the specified component, or
equivalently the number of fractional bits.
|
CBlkWTData |
getNextCodeBlock(int n,
CBlkWTData cblk)
Returns the next code-block in the current tile for the specified
component, as a copy (see below).
|
CBlkWTData |
getNextInternCodeBlock(int n,
CBlkWTData cblk)
Returns the next code-block in the current tile for the specified
component.

When changing the current tile (through 'setTile()' or 'nextTile()') this method will always return the first code-block, as if this method was never called before for the new current tile.
The data returned by this method is always a copy of the internal data of this object, if any, and it can be modified "in place" without any problems after being returned. The 'offset' of the returned data is 0, and the 'scanw' is the same as the code-block width. The 'magbits' of the returned data is not set by this method and should be ignored. See the 'CBlkWTData' class.
The 'ulx' and 'uly' members of the returned 'CBlkWTData' object contain the coordinates of the top-left corner of the block, with respect to the tile, not the subband.

- If non-null this object will be used to return the new
code-block. If null a new one will be allocated and returned. If the
"data" array of the object is non-null it will be reused, if possible,
to return the data.CBlkWTData
CBlkWTData getNextInternCodeBlock(int n, CBlkWTData cblk)
When changing the current tile (through 'setTile()' or 'nextTile()') this method will always return the first code-block, as if this method was never called before for the new current tile.
The data returned by this method can be the data in the internal buffer of this object, if any, and thus can not be modified by the caller. The 'offset' and 'scanw' of the returned data can be arbitrary. The 'magbits' of the returned data is not set by this method and should be ignored. See the 'CBlkWTData' class.
The 'ulx' and 'uly' members of the returned 'CBlkWTData' object contain the coordinates of the top-left corner of the block, with respect to the tile, not the subband.
