Interface BackwardAnalysis<V extends AbstractValue<V>,S extends Store<S>,T extends BackwardTransferFunction<V,S>>

Type Parameters:

V - the abstract value type to be tracked by the analysis

S - the store type used in the analysis

T - the backward transfer function type that is used to approximate run-time behavior

Method Details

getEntryStore

@Nullable S getEntryStore()

Get the output store at the entry block of a given control flow graph. For a backward analysis, the output store contains the analyzed flow information from the exit block to the entry block.

Returns:

the output store at the entry block of a given control flow graph
