Interface Summary

Interface	Description
AbstractValue<V extends AbstractValue<V>>	An abstract value used in the org.checkerframework.dataflow analysis.
Analysis<V extends AbstractValue<V>,S extends Store<S>,T extends TransferFunction<V,S>>	This interface defines a dataflow analysis, given a control flow graph and a transfer function.
BackwardAnalysis<V extends AbstractValue<V>,S extends Store<S>,T extends BackwardTransferFunction<V,S>>	This interface defines a backward analysis, given a control flow graph and a backward transfer function.
BackwardTransferFunction<V extends AbstractValue<V>,S extends Store<S>>	Interface of a backward transfer function for the abstract interpretation used for the backward flow analysis.
ForwardAnalysis<V extends AbstractValue<V>,S extends Store<S>,T extends ForwardTransferFunction<V,S>>	This interface defines a forward analysis, given a control flow graph and a forward transfer function.
ForwardTransferFunction<V extends AbstractValue<V>,S extends Store<S>>	Interface of a forward transfer function for the abstract interpretation used for the forward flow analysis.
Store<S extends Store<S>>	A store is used to keep track of the information that the org.checkerframework.dataflow analysis has accumulated at any given point in time.
TransferFunction<V extends AbstractValue<V>,S extends Store<S>>	Interface of a transfer function for the abstract interpretation used for the flow analysis.

Class Summary

Class	Description
AbstractAnalysis<V extends AbstractValue<V>,S extends Store<S>,T extends TransferFunction<V,S>>	Implementation of common features for BackwardAnalysisImpl and ForwardAnalysisImpl.
AbstractAnalysis.Worklist	A worklist is a priority queue of blocks in which the order is given by depth-first ordering to place non-loop predecessors ahead of successors.
AnalysisResult<V extends AbstractValue<V>,S extends Store<S>>	An AnalysisResult represents the result of a org.checkerframework.dataflow analysis by providing the abstract values given a node or a tree.
BackwardAnalysisImpl<V extends AbstractValue<V>,S extends Store<S>,T extends BackwardTransferFunction<V,S>>	An implementation of a backward analysis to solve a org.checkerframework.dataflow problem given a control flow graph and a backward transfer function.
ConditionalTransferResult<V extends AbstractValue<V>,S extends Store<S>>	Implementation of a TransferResult with two non-exceptional store; one for the 'then' edge and one for 'else'.
