Constructor Detail

FilteredCallGraph

public FilteredCallGraph(CallGraph base,
                         FilteredCallGraph.Filter filter)

Method Detail

getRoots

public Collection getRoots()

Description copied from class: CallGraph

Returns the collection of root methods for this call graph.

Specified by:

getRoots in interface jwutil.graphs.Graph

Specified by:

getRoots in class CallGraph

setRoots

public void setRoots(Collection roots)

Description copied from class: CallGraph

Sets up the root methods to be the given set. Later call graph queries use the value that you pass in here. Implementing this method is optional -- it is only necessary if you use methods that require a root set, like getReachableMethods().

Specified by:

setRoots in class CallGraph

Parameters:

roots - collection of root methods

getTargetMethods

public Collection getTargetMethods(Object context,
                                   ProgramLocation callSite)

Description copied from class: CallGraph

Returns the possible target methods of the given call site under the given context. The interpretation of the context object is specific to the type of call graph.

Specified by:

getTargetMethods in class CallGraph

Returns:

Collection of jq_Methods that are the possible targets
