Method Detail

build

public void build(int numLevels,
                  int cellSize)

computeBounds

public void computeBounds(Dimension dim,
                          float[] xs,
                          float[] ys)

computeExtremesFromChildren

protected void computeExtremesFromChildren()

computeExtremesFromLocations

protected void computeExtremesFromLocations(Dimension dim,
                                            float[] xs,
                                            float[] ys)

getSizeInBytes

public long getSizeInBytes()

Description copied from interface: Cacheable

Retrieves the approximate size of this object in bytes. Implementors are encouraged to calculate the exact size for smaller objects, but use approximate values for objects that include such large components that the approximation would produce an error so small that the extra computation would be wasteful.

Specified by:

getSizeInBytes in interface Cacheable

Returns:

this Cacheable object's size in bytes

intersects

public boolean intersects(float x,
                          float y)

makeChildCell

protected ImageInterpolator.Cell makeChildCell(int m0,
                                               int m1,
                                               int n0,
                                               int n1)

split

public ImageInterpolator.Cell[] split(int mm0,
                                      int mm1,
                                      int nn0,
