Interface IReversibleFlowFunction
- All Superinterfaces:
IFlowFunction
,IUnaryFlowFunction
- All Known Implementing Classes:
IdentityFlowFunction
,SingletonFlowFunction
,VectorGenFlowFunction
,VectorKillFlowFunction
A flow function corresponding to an edge in the supergraph. A reversible flow-function supports a
getSources operation that allows computing backwards flow. At the very least, this is required in
IFDS by call functions for which sources need to be found to handle insertion of summary edges.
