Specified by:

getSources in interface IReversibleFlowFunction

Returns:

set of d1 such that (d1,d2) is an edge in this distributive function's graph representation, or null if there are none

make

public static VectorKillFlowFunction make(com.ibm.wala.util.intset.IntSet kill)

Parameters:

kill - the intset of facts which should be killed by a function

Returns:

an instance of a flow function which kills these facts

toString
