Class JvmMemoryLocationMergeJoinOperator<ContentT extends AbstractState<ContentT>>

java.lang.Object

proguard.analysis.cpa.jvm.domain.memory.JvmMemoryLocationMergeJoinOperator<ContentT>

Type Parameters:

ContentT - The content of the jvm states for the traced analysis. For example, this can be a SetAbstractState of taints for taint analysis or a ValueAbstractState for value analysis.

All Implemented Interfaces:

MergeOperator<JvmMemoryLocationAbstractState<ContentT>>

public final class JvmMemoryLocationMergeJoinOperator<ContentT extends AbstractState<ContentT>>
extends java.lang.Object
implements MergeOperator<JvmMemoryLocationAbstractState<ContentT>>

This MergeOperator applies the join operator to its arguments sharing the same memory location.

Description copied from interface: MergeOperator

The operator uses the abstractState1 to weaken abstractState2 depending on precision. Thus, it is asymmetric regarding its first two parameters. E.g., return abstractState2 for no merging. To guarantee the correct behavior of the algorithm implementations must have no side effects.
