Method Details

equals

public boolean equals(Object obj)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

getType

public IClass getType()

getConcreteType

public IClass getConcreteType()

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

getInstanceKeysForPEI

public static InstanceKey[] getInstanceKeysForPEI(SSAInstruction pei,
 IClassHierarchy cha)

Parameters:

pei - a PEI instruction

cha - governing class hierarchy

Returns:

a set of ConcreteTypeKeys that represent the exceptions the PEI may throw.

Throws:

IllegalArgumentException - if pei is null

getCreationSites

public Iterator<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.

Specified by:

getCreationSites in interface InstanceKey
