Constructor Detail

SelfCalls

public SelfCalls(ClassContext classContext)

Constructor.

Parameters:

classContext - the ClassContext for the class

Method Detail

execute

public void execute()
             throws CFGBuilderException

Find the self calls.

Throws:

CFGBuilderException

getCallGraph

public CallGraph getCallGraph()

Get the self call graph for the class.

calledMethodIterator

public java.util.Iterator<org.apache.bcel.classfile.Method> calledMethodIterator()

Get an Iterator over self-called methods.

wantCallsFor

public boolean wantCallsFor(org.apache.bcel.classfile.Method method)

Determine whether we are interested in calls for the given method. Subclasses may override. The default version returns true for every method.

Parameters:

method - the method

Returns:

true if we want call sites for the method, false if not

callSiteIterator

public java.util.Iterator<CallSite> callSiteIterator()

Get an Iterator over all self call sites.

hasSynchronization

public boolean hasSynchronization()

Does this class contain any explicit synchronization?

scan

private void scan(CallGraphNode node)
           throws CFGBuilderException

Scan a method for self call sites.

Parameters:

node - the CallGraphNode for the method to be scanned

Throws:

CFGBuilderException

isSelfCall

private org.apache.bcel.classfile.Method isSelfCall(org.apache.bcel.generic.InvokeInstruction inv)

Is the given instruction a self-call?
