getDependencyRegion
Returns the region of input data is is required to generate outputRgn.- Specified by:
getDependencyRegion
in interfaceFilter
- Overrides:
getDependencyRegion
in classAbstractRable
- Parameters:
srcIndex
- The source to do the dependency calculation for.outputRgn
- The region of output you are interested in generating dependencies for. The is given in the user coordiate system for this node.- Returns:
- The region of input required. This is in the user coordinate system for the source indicated by srcIndex.
-
getDirtyRegion
This calculates the region of output that is affected by a change in a region of input.- Specified by:
getDirtyRegion
in interfaceFilter
- Overrides:
getDirtyRegion
in classAbstractRable
- Parameters:
srcIndex
- The input that inputRgn reflects changes in.inputRgn
- the region of input that has changed, used to calculate the returned shape. This is given in the user coordinate system of the source indicated by srcIndex.- Returns:
- The region of output that would be invalid given a change to inputRgn of the source selected by srcIndex. this is in the user coordinate system of this node.
