Modifier and Type	Method	Description
`Context`	`getCalleeTarget(CGNode caller, CallSiteReference site, IMethod callee, InstanceKey[] receiver)`	Given a calling node and a call site, returns the Context in which the callee should be evaluated.
`protected abstract int`	`getLength(CGNode caller, CallSiteReference site, IMethod target)`
`IntSet`	`getRelevantParameters(CGNode caller, CallSiteReference site)`	Given a calling node and a call site, return the set of parameters based on which this selector may choose to specialize contexts.
