All Implemented Interfaces:

PointerAnalysis<InstanceKey>

public class TypeBasedPointerAnalysis
extends AbstractPointerAnalysis

A trivial field-based pointer analysis solution, which only uses the information of which types (classes) are live.

Method Details

make

public static TypeBasedPointerAnalysis make(AnalysisOptions options,
 Collection<IClass> klasses,
 CallGraph cg)
                                     throws AssertionError

Throws:

AssertionError

getPointsToSet

public OrdinalSet<InstanceKey> getPointsToSet(PointerKey key)
                                       throws IllegalArgumentException

Parameters:

key - representative of an equivalence class of pointers

Returns:

Set of InstanceKey, representing the instance abstractions that define the points-to set computed for the pointer key

Throws:

IllegalArgumentException

getHeapModel

public HeapModel getHeapModel()

Returns:

an Object that determines how to model abstract locations in the heap.

getPointerKeys

public Collection<PointerKey> getPointerKeys()

Returns:

all pointer keys known

isFiltered

public boolean isFiltered(PointerKey pk)

Description copied from interface: PointerAnalysis

did the pointer analysis use a type filter for a given points-to set? (this is ugly).

getClassHierarchy

public IClassHierarchy getClassHierarchy()
