Class CompositeHeapTransferRelation

java.lang.Object

proguard.analysis.cpa.jvm.domain.reference.CompositeHeapTransferRelation

All Implemented Interfaces:

ProgramLocationDependentForwardTransferRelation<JvmCfaNode,JvmCfaEdge,MethodSignature>, ProgramLocationDependentTransferRelation<JvmCfaNode,JvmCfaEdge,MethodSignature>, TransferRelation, WrapperTransferRelation

public class CompositeHeapTransferRelation
extends java.lang.Object
implements WrapperTransferRelation, ProgramLocationDependentForwardTransferRelation<JvmCfaNode,JvmCfaEdge,MethodSignature>

A wrapper class around multiple JvmTransferRelations applying them elementwise to CompositeHeapJvmAbstractStates. The CompositeHeapJvmAbstractState.REFERENCE_STATE_INDEXth transfer relation must be JvmReferenceTransferRelation to match the structure of CompositeHeapTransferRelation.
