Interface ContextBasedMatcher

public interface ContextBasedMatcher

Pointcut expression interface for pointcut expressions returned by a PointcutDesignatorHandler. Provides an additional matching method for matching based on context information over and above that normally used by AspectJ.

Method Summary

Modifier and Type	Method and Description
boolean	couldMatchJoinPointsInType(java.lang.Class aClass) Deprecated. use couldMatchJoinPointsInType(Class,MatchingContext) instead
boolean	couldMatchJoinPointsInType(java.lang.Class aClass, MatchingContext matchContext) return true iff this matcher could ever match a join point in the given type, may also use any match context information available
boolean	matchesDynamically(MatchingContext matchContext) Called during processing of ShadowMatch.matchesJoinPoint when matchesStatically returned FuzzyBoolean.MAYBE.
FuzzyBoolean	matchesStatically(MatchingContext matchContext) Return FuzzyBoolean.YES if a join point with the given matching context is always matched.
boolean	mayNeedDynamicTest() return true if matchesStatically can ever return FuzzyBoolean.MAYBE (necessitating a per-join point test to determine matching at a given join point).

Method Detail

couldMatchJoinPointsInType

boolean couldMatchJoinPointsInType(java.lang.Class aClass)

Deprecated. use couldMatchJoinPointsInType(Class,MatchingContext) instead

return true iff this matcher could ever match a join point in the given type

couldMatchJoinPointsInType

boolean couldMatchJoinPointsInType(java.lang.Class aClass,
                                   MatchingContext matchContext)

return true iff this matcher could ever match a join point in the given type, may also use any match context information available

Since:

1.5.1

mayNeedDynamicTest

boolean mayNeedDynamicTest()

return true if matchesStatically can ever return FuzzyBoolean.MAYBE (necessitating a per-join point test to determine matching at a given join point).

matchesStatically

FuzzyBoolean matchesStatically(MatchingContext matchContext)

Return FuzzyBoolean.YES if a join point with the given matching context is always matched. Return FuzzyBoolean.NO if a join point with the given matching context is never matched. Return FuzzyBoolean.MAYBE if a match cannot be determined statically (whilst generating a ShadowMatch), and must be determined on a per-join point basis.

matchesDynamically

boolean matchesDynamically(MatchingContext matchContext)

Called during processing of ShadowMatch.matchesJoinPoint when matchesStatically returned FuzzyBoolean.MAYBE.
