接口 ExpandOperator<ContentT extends AbstractState<ContentT>>

类型参数:

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

所有已知实现类:

DefaultExpandOperator, TaintExpandOperator, ValueExpandOperator

public interface ExpandOperator<ContentT extends AbstractState<ContentT>>

This operator is used to recover the information discarded when entering a procedure block depending on the domain-specific analysis.

方法概要

修饰符和类型	方法	说明
JvmAbstractState<ContentT>	expand(JvmAbstractState<ContentT> expandedInitialState, JvmAbstractState<ContentT> reducedExitState, JvmCfaNode blockEntryNode, Call call)	Reconstructs the state of the caller of a procedure using the information of the expanded initial state, the reduced exit state, the block entry node (that can be used to retrieve the CFA subgraph of the function), and the call to the procedure.

expand

JvmAbstractState<ContentT> expand(JvmAbstractState<ContentT> expandedInitialState,
                                  JvmAbstractState<ContentT> reducedExitState,
                                  JvmCfaNode blockEntryNode,
                                  Call call)

Reconstructs the state of the caller of a procedure using the information of the expanded initial state, the reduced exit state, the block entry node (that can be used to retrieve the CFA subgraph of the function), and the call to the procedure.

参数:

expandedInitialState - the entry state of the called procedure before any reduction

reducedExitState - the state of the called procedure in its exit node

blockEntryNode - the entry node of the called procedure

call - the information of the call to the procedure

返回:

The state of the caller after the procedure call, eventually with some collisions of identifiers that need the RebuildOperator to be solved
