Interface EdgeFilter<T extends IBasicBlock<?>>

All Known Implementing Classes:

ExceptionAnalysis2EdgeFilter, ExceptionFilter2EdgeFilter, NegativeGraphFilter

public interface EdgeFilter<T extends IBasicBlock<?>>

This class is used by the PrunedCFG to determine which edges in a given CFG should be kept in the pruned version.

Method Summary

Modifier and Type	Method and Description
boolean	hasExceptionalEdge(T src, T dst) This method must return true if and only if an exceptional edge from src to dst exists in the original CFG and should be kept for the pruned version of that CFG.
boolean	hasNormalEdge(T src, T dst) This method must return true if and only if a normal edge from src to dst exists in the original CFG and should be kept for the pruned version of that CFG.

Method Detail

hasNormalEdge

boolean hasNormalEdge(T src,
                      T dst)

This method must return true if and only if a normal edge from src to dst exists in the original CFG and should be kept for the pruned version of that CFG. Note that this must _must_ return false for any normal edge that is not in the original CFG.

hasExceptionalEdge

boolean hasExceptionalEdge(T src,
                           T dst)

This method must return true if and only if an exceptional edge from src to dst exists in the original CFG and should be kept for the pruned version of that CFG. Note that this must _must_ return false for any exceptional edge that is not in the original CFG.
