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

getValue

public T getValue()

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.
