java.lang.Object

proguard.analysis.cpa.jvm.state.heap.JvmForgetfulHeapAbstractState<StateT>

所有已实现的接口:

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

public class JvmForgetfulHeapAbstractState<StateT extends AbstractState<StateT>>
extends Object
implements JvmHeapAbstractState<StateT>

This is a forgetful stub heap implementation. It does not change and always returns the default value.

构造器详细资料

JvmForgetfulHeapAbstractState

public JvmForgetfulHeapAbstractState(StateT defaultValue)

Create a forgetful heap abstract state returning the specified value for all queries.

参数:

defaultValue - the value to be returned by memory accesses

方法详细资料

getFieldOrDefault

public <T> StateT getFieldOrDefault(T object,
 String fqn,
 StateT defaultValue)

从接口复制的说明: JvmHeapAbstractState

Returns a field fqn from a reference object. If there is no abstract state representing the field, returns the defaultValue

指定者:

getFieldOrDefault 在接口中 JvmHeapAbstractState<StateT extends AbstractState<StateT>>

setField

public <T> void setField(T object,
 String fqn,
 StateT value)

从接口复制的说明: JvmHeapAbstractState

Sets a value to a field fqn of a referenced object.

指定者:

setField 在接口中 JvmHeapAbstractState<StateT extends AbstractState<StateT>>

getArrayElementOrDefault

public <T> StateT getArrayElementOrDefault(T array,
 StateT index,
 StateT defaultValue)

从接口复制的说明: JvmHeapAbstractState

Returns an array element at the specified index or the defaultValue, if the element is unset.

指定者:

getArrayElementOrDefault 在接口中 JvmHeapAbstractState<StateT extends AbstractState<StateT>>

setArrayElement

public <T> void setArrayElement(T array,
 StateT index,
 StateT value)

从接口复制的说明: JvmHeapAbstractState

指定者:

setArrayElement 在接口中 JvmHeapAbstractState<StateT extends AbstractState<StateT>>

newObject

public StateT newObject(String className,
 JvmCfaNode creationCite)

从接口复制的说明: JvmHeapAbstractState

Creates a new object of a given class at a specific program point and returns a reference to it.

指定者:

newObject 在接口中 JvmHeapAbstractState<StateT extends AbstractState<StateT>>

newArray

public StateT newArray(String type,
 List<StateT> dimensions,
 JvmCfaNode creationCite)

从接口复制的说明: JvmHeapAbstractState
