Method Details

understands

public boolean understands(CGNode node)

Description copied from interface: CHAContextInterpreter

Does this object understand the given method? The caller had better check this before inquiring on other properties.

Specified by:

understands in interface CHAContextInterpreter

iterateNewSites

public Iterator<NewSiteReference> iterateNewSites(CGNode node)

Specified by:

iterateNewSites in interface CHAContextInterpreter

Specified by:

iterateNewSites in interface RTAContextInterpreter

Returns:

an Iterator of the types that may be allocated by a given method in a given context.

iterateCallSites

public Iterator<CallSiteReference> iterateCallSites(CGNode node)

Specified by:

iterateCallSites in interface CHAContextInterpreter

Returns:

an Iterator of the call statements that may execute in a given method for a given context

iterateFieldsRead

public Iterator<FieldReference> iterateFieldsRead(CGNode node)

Specified by:

iterateFieldsRead in interface RTAContextInterpreter

Returns:

iterator of FieldReference

iterateFieldsWritten

public Iterator<FieldReference> iterateFieldsWritten(CGNode node)

Specified by:

iterateFieldsWritten in interface RTAContextInterpreter

Returns:

iterator of FieldReference

recordFactoryType

public boolean recordFactoryType(CGNode node,
 IClass klass)

Description copied from interface: RTAContextInterpreter

record that the "factory" method of a node should be interpreted to allocate a particular class.

TODO: this is a little ugly, is there a better place to move this?

Specified by:

recordFactoryType in interface RTAContextInterpreter

Returns:

true iff a NEW type was recorded, false if the type was previously recorded.

toString

public String toString()

Overrides:

toString in class Object
