java.lang.Object

proguard.analysis.cpa.jvm.operators.DefaultReduceOperator<SetAbstractState<TaintSource>>

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

All Implemented Interfaces:

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.

Constructor Details

TaintReduceOperator

public TaintReduceOperator(boolean reduceHeap)

Create the taint reduce operator for the JVM.

Parameters:

reduceHeap - whether reduction of the heap is performed

TaintReduceOperator

public TaintReduceOperator(boolean reduceHeap,
 Map<Signature,Set<TaintSource>> taintSources)

Create the taint reduce operator for the JVM.

Parameters:

reduceHeap - whether reduction of the heap is performed

taintSources - collection of taint sources

onMethodEntry

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

Description copied from interface: 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.

Parameters:

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

isCallStatic - is the called method static

Returns:

the state after performing additional operations or untouched state by default
