Method Detail

getSpaceBounds

public ISBounds getSpaceBounds()

added by Sridhar

set

public abstract boolean set(IndexSpaceID id)

Set the stencil element containing the id to "active". If it is already active, then the method returns false. Returns true otherwise.

setElement

public abstract boolean setElement(IndexSpaceID id)

Set the stencil element with index corresponding to id to "active. id should already have been mapped to the partitioning space. If it is already active, then the method returns false. Returns true otherwise.

get

public abstract boolean get(IndexSpaceID id)

Return true if the given id maps to an active stencil element, false otherwise.

getIndexedBounds

public ISBounds getIndexedBounds(int index)

Return a new ISBounds with shape equal to the indexed stencil element.

getIndexedBounds

public abstract ISBounds getIndexedBounds(ISBounds stencilBounds,
                                          int index)

sets the argument ISBounds to the bounds of the stencil element stored in this stencil list

size

public abstract int size()

return number of elements contained by this stencil

dim

public final int dim()

Return the dimensionality of the stencil domain.
