                        LocalCapture localCapture,
                        java.lang.String identifier)

Make a new CallbackInjector with the supplied args

Parameters:

info - information about this injector

cancellable - True if injections performed by this injector should be cancellable

localCapture - Local variable capture behaviour

sanityCheck

protected void sanityCheck(Target target,
                           java.util.List<InjectionPoint> injectionPoints)

Overrides:
