Constructor Detail

GBoundsGapIterator

public GBoundsGapIterator(GBounds space,
                  float[] shape,
                  float[] gaps)

Construct an GBoundsGapIterator that will traverse the given space with an an GBounds of the given shape (dimensions). The last argument specifies the desired gaps between GBounds in each dimension. A gaps array of all zeros means the generated GBounds all abut exactly. If a gap value is positive, then there will be that many rows/columns between the generated GBounds in that dimension. If any of the gaps are negative, then the generated GBounds will overlap in the corresponding dimension. ( e.g. a gap of -1 means the Bounds will overlap by 1 row/column.) Values in the shape array must be >= 1, and values in the gaps array must allow the iterator to make forward progress. In particular, for negative gap values, the magnitude must be less than the shape value of the same dimension.
