proguard.analysis.cpa.jvm.domain.taint.TaintReduceOperator

所有已实现的接口:

ReduceOperator<SetAbstractState<TaintSource>>

public class TaintReduceOperator
extends DefaultReduceOperator<SetAbstractState<TaintSource>>

This ReduceOperator inherits all the functionalities of a DefaultReduceOperator while adding taint-analysis specific functionalities.

TaintReduceOperator

public TaintReduceOperator(boolean reduceHeap)

Create the taint reduce operator for the JVM.

参数:

reduceHeap - whether reduction of the heap is performed

TaintReduceOperator

onMethodEntry

public JvmAbstractState<SetAbstractState<TaintSource>> onMethodEntry(JvmAbstractState<SetAbstractState<TaintSource>> reducedState,
 boolean isCallStatic)

从接口复制的说明: ReduceOperator

Performs additional operations on the reduced state (i.e. on the method entry state). Does nothing by default. NB: since this is still part of the reduction operation the result of this method is the state used by the analysis and part of the cache key for the called method.

参数:

reducedState - reduced state (i.e., the entry state of the called method)

isCallStatic - is the called method static

返回:

the state after performing additional operations or untouched state by default
