  abc.weaving.weaver.ShadowPoints

Direct Known Subclasses:

RebindingShadowPoints

public class ShadowPoints
extends java.lang.Object

A data structure to keep track of the beginning and end points of a pointcut shadow. Once created, the beginning and end points will alway point to NOP statements. Weaving will take place just after the beginning NOP and just before the ending NOP. Each abc.weaving.matching.AdviceApplication instance refers to a ShadowPoints instance. A ShadowPoints instance is shared between all AdviceApplications that apply to a specific pointcut.

Constructor Detail

ShadowPoints

public ShadowPoints(SootMethod container,
                    Stmt b,
                    Stmt e)

Should always get references to NopStmts. For all types of pointcuts both b and e will be non-null. Even handler pointcuts have an ending nop, so they can handle BeforeAfterAdvice for cflow etc; but the nop will initially be right next to the starting nop.
