proguard.analysis.cpa.jvm.state.heap.tree.JvmShallowHeapAbstractState<ReferenceT,StateT>

所有已实现的接口:

AbstractState<JvmHeapAbstractState<StateT>>, JvmHeapAbstractState<StateT>

public class JvmShallowHeapAbstractState<ReferenceT,StateT extends AbstractState<StateT>>
extends java.lang.Object
implements JvmHeapAbstractState<StateT>

A shallow heap models objects as atomic abstract states thus having only one level of depth. Object fields are not modeled. References of wrong types are ignored.
