Method Detail

getMethod

IMethod getMethod()

Return the method this CGNode represents. This value will never be null.

Returns:

the target IMethod for this CGNode.

getContext

Context getContext()

Return the context this CGNode represents. This value will never be null.

Returns:

the Context for this CGNode.

addTarget

@Deprecated
boolean addTarget(CallSiteReference site,
                           CGNode target)

Deprecated.

This is for use only by call graph builders ... not by the general public. Clients should not use this. Record that a particular call site might resolve to a call to a particular target node. Returns true if this is a new target

getIR

IR getIR()

Returns:

the "default" IR for this node used by the governing call graph

getDU

DefUse getDU()

Returns:

DefUse for the "default" IR for this node used by the governing call graph

iterateNewSites

Iterator<NewSiteReference> iterateNewSites()

Returns:

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

iterateCallSites

Iterator<CallSiteReference> iterateCallSites()

Returns:

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