Method Details

getPointerKeyForLocal

public PointerKey getPointerKeyForLocal(CGNode node,
 int valueNumber)

Specified by:

getPointerKeyForLocal in interface PointerKeyFactory

Returns:

the PointerKey that acts as a representative for the class of pointers that includes the local variable identified by the value number parameter.

getFilteredPointerKeyForLocal

public FilteredPointerKey getFilteredPointerKeyForLocal(CGNode node,
 int valueNumber,
 FilteredPointerKey.TypeFilter filter)

Specified by:

getFilteredPointerKeyForLocal in interface PointerKeyFactory

Returns:

the PointerKey that acts as a representative for the class of pointers that includes the local variable identified by the value number parameter.

getPointerKeyForReturnValue

public PointerKey getPointerKeyForReturnValue(CGNode node)

Specified by:

getPointerKeyForReturnValue in interface PointerKeyFactory

Returns:

the PointerKey that acts as a representative for the class of pointers that includes the return value for a node

getPointerKeyForExceptionalReturnValue

public PointerKey getPointerKeyForExceptionalReturnValue(CGNode node)

Specified by:

getPointerKeyForExceptionalReturnValue in interface PointerKeyFactory

Returns:

the PointerKey that acts as a representative for the class of pointers that includes the exceptional return value

getPointerKeyForStaticField

public PointerKey getPointerKeyForStaticField(IField f)

Specified by:

getPointerKeyForStaticField in interface PointerKeyFactory

Returns:

the PointerKey that acts as a representative for the class of pointers that includes the contents of the static field

getPointerKeyForObjectCatalog

public PointerKey getPointerKeyForObjectCatalog(InstanceKey I)

Description copied from interface: AstPointerKeyFactory

get a pointer key for the object catalog of I. The object catalog stores the names of all known properties of I.

Specified by:

getPointerKeyForObjectCatalog in interface AstPointerKeyFactory

getPointerKeyForInstanceField

public PointerKey getPointerKeyForInstanceField(InstanceKey I,
 IField f)

Specified by:

getPointerKeyForInstanceField in interface PointerKeyFactory

Returns:

the PointerKey that acts as a representation for the class of pointers that includes the given instance field.

getPointerKeyForArrayContents

public PointerKey getPointerKeyForArrayContents(InstanceKey I)

Description copied from interface: PointerKeyFactory

TODO: expand this API to differentiate between different array indices

Specified by:

getPointerKeyForArrayContents in interface PointerKeyFactory

Parameters:

I - an InstanceKey representing an abstract array

Returns:

the PointerKey that acts as a representation for the class of pointers that includes the given array contents.

getPointerKeysForReflectedFieldWrite

public Iterator<PointerKey> getPointerKeysForReflectedFieldWrite(InstanceKey I,
 InstanceKey F)

Specified by:

getPointerKeysForReflectedFieldWrite in interface AstPointerKeyFactory

getFieldNameType

protected IClass getFieldNameType(InstanceKey F)

get type for F appropriate for use in a field name.

getInstanceFieldPointerKeyForConstant

protected PointerKey getInstanceFieldPointerKeyForConstant(InstanceKey I,
 ConstantKey<?> F)

if F is a supported constant representing a field, return the corresponding InstanceFieldKey for I. Otherwise, return null.

getPointerKeysForReflectedFieldRead

public Iterator<PointerKey> getPointerKeysForReflectedFieldRead(InstanceKey I,
 InstanceKey F)

Specified by:

getPointerKeysForReflectedFieldRead in interface AstPointerKeyFactory
