Method Detail

getTargets

public SparseIntSet getTargets(int i)

Specified by:

getTargets in interface IUnaryFlowFunction

Returns:

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

getSources

public SparseIntSet getSources(int i)

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(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
