Interface ShadowMatch

All Known Implementing Classes:

ShadowMatchImpl, StandardShadowMatchImpl

public interface ShadowMatch

The result of asking a PointcutExpression to match at a shadow (method execution, handler, constructor call, and so on).

Method Summary

Modifier and Type	Method and Description
boolean	alwaysMatches() True iff the pointcut expression will match any join point at this shadow (for example, any call to the given method).
JoinPointMatch	matchesJoinPoint(java.lang.Object thisObject, java.lang.Object targetObject, java.lang.Object[] args) Return the result of matching a join point at this shadow with the given this, target, and args.
boolean	maybeMatches() True if the pointcut expression may match some join points at this shadow (for example, some calls to the given method may match, depending on the type of the caller).
boolean	neverMatches() True iff the pointcut expression can never match any join point at this shadow (for example, the pointcut will never match a call to the given method).
void	setMatchingContext(MatchingContext aMatchContext) Set a matching context to be used when matching join points.

Method Detail

alwaysMatches

boolean alwaysMatches()

True iff the pointcut expression will match any join point at this shadow (for example, any call to the given method).

maybeMatches

boolean maybeMatches()

True if the pointcut expression may match some join points at this shadow (for example, some calls to the given method may match, depending on the type of the caller).

If alwaysMatches is true, then maybeMatches is always true.

neverMatches

boolean neverMatches()

True iff the pointcut expression can never match any join point at this shadow (for example, the pointcut will never match a call to the given method).

matchesJoinPoint

JoinPointMatch matchesJoinPoint(java.lang.Object thisObject,
                                java.lang.Object targetObject,
                                java.lang.Object[] args)

Return the result of matching a join point at this shadow with the given this, target, and args.

Parameters:

thisObject - the object bound to this at the join point

targetObject - the object bound to target at the join point

args - the arguments at the join point

Returns:

setMatchingContext

void setMatchingContext(MatchingContext aMatchContext)

Set a matching context to be used when matching join points.
