          Description

Interface Summary
IBinaryReturnFlowFunction A binary flow function corresponding to a return statements combining information from the call site and the exit site.
IFlowFunction A flow function corresponding to an edge in the supergraph.
IFlowFunctionMap<T> A map from an edge in a supergraph to a flow function
IMergeFunction Special case: if supportsMerge(), then the problem is not really IFDS anymore.
IPartiallyBalancedFlowFunctions<T> Flow functions for a PartiallyBalancedTabulationProblem
IReversibleFlowFunction A flow function corresponding to an edge in the supergraph.
ISupergraph<T,P> A supergraph as defined by Reps, Horwitz, and Sagiv POPL95
ITabulationWorklist<T>  
IUnaryFlowFunction A flow function corresponding to an edge in the supergraph.
PartiallyBalancedTabulationProblem<T,P,F> A TabulationProblem with additional support for computing with partially balanced parentheses.
TabulationDomain<F,T> Domain of facts for tabulation.
TabulationProblem<T,P,F> Representation of a Dyck-language graph reachability problem for the tabulation solver.
TabulationResult<T,P,F> The solution of a tabulation problem: a mapping from supergraph node -> bit vector representing the dataflow facts that hold at the entry to the supergraph node.
 

Class Summary
BackwardsSupergraph<T,P> A "reversed" supergraph for backwards analysis.
BoundedPartiallyBalancedSolver<T,P,F> A TabulationSolver that gives up after a finite bound.
BoundedTabulationSolver<T,P,F> A TabulationSolver that gives up after a finite bound.
CallFlowEdges A set of call flow edges which lead to a particular procedure entry s_p.
ICFGSupergraph Forward supergraph induced over an ExplodedInterproceduralCFG This should lazily build the supergraph as it is explored.
IdentityFlowFunction A flow function where out == in
IdentityFlowFunctions<T> A silly debugging aid that always returns the identity flow function
KillEverything A flow function that kills everything (even 0)
LocalPathEdges A set of path edges for a particular procedure entry s_p.
LocalSummaryEdges A set of summary edges for a particular procedure.
PartiallyBalancedTabulationSolver<T,P,F> Utilities for dealing with tabulation with partially balanced parentheses.
PathEdge<T> an individual edge ->
SingletonFlowFunction A flow function which has only the edge 0 -> dest
TabulationSolver<T,P,F> A precise interprocedural tabulation solver.
UnorderedDomain<T,U> A TabulationDomain with no build-in partial order defining priority.
VectorGenFlowFunction A function which gens a vector of outgoing dataflow facts
VectorKillFlowFunction A function which kills a vector of incoming dataflow facts
 

Exception Summary
TabulationCancelException A CancelException thrown during tabulation; holds a pointer to a partial TabulationSolver.Result.
