Method Detail

disjointUnion

public static ExplicitCellStream disjointUnion(ExplicitCellStream stream1,
                               ExplicitCellStream stream2)

This function produces a cell complex that is the disjoint union of two cell complexes.

Parameters:

stream1 - the first cell complex

stream2 - the second cell complex

Returns:

the disjoint union of the supplied complexes

identifyPoints

public static void identifyPoints(ExplicitCellStream stream,
                  int[] vertices)

This function collapses the points in the supplied array to a single point.

Parameters:

stream - the cell complex

vertices - the vertices to identify
