Class AllocationSite

java.lang.Object

com.ibm.wala.ipa.callgraph.propagation.AllocationSite

All Implemented Interfaces:

ContextItem, InstanceKey

public class AllocationSite
extends Object
implements InstanceKey

An InstanceKey which represents a NewSiteReference in some IMethod. Note that this differs from AllocationSiteInNode, which represents an allocation in a CGNode that may carry some Context. This type is useful for a context-insensitive heap abstraction.

Description copied from interface: InstanceKey

For now, we assert that each InstanceKey represents a set of classes which are all of the same concrete type (modulo the fact that all arrays of references are considered concrete type []Object;)

Specified by:

getConcreteType in interface InstanceKey

hashCode

public int hashCode()

Overrides:

hashCode in class Object

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

getCreationSites

public Iterator<com.ibm.wala.util.collections.Pair<CGNode,NewSiteReference>> getCreationSites(CallGraph CG)

Description copied from interface: InstanceKey

Get the creation sites of this, i.e., the statements that may allocate objects represented by this. A creation site is a pair (n,s), where n is the containing CGNode in the given CallGraph CG and s is the allocating NewSiteReference.
