Document

If the test uses any of the this, target, at_this, at_target, and at_annotation vars, then it tests subtype sensitive vars.

Usage

From source file:org.springframework.aop.aspectj.AspectJExpressionPointcut.java

@Override
public boolean matches(Method method, @Nullable Class<?> targetClass, boolean beanHasIntroductions) {
    obtainPointcutExpression();/*from w w  w  .  j a  v  a  2 s .c  o m*/
    Method targetMethod = AopUtils.getMostSpecificMethod(method, targetClass);
    ShadowMatch shadowMatch = getShadowMatch(targetMethod, method);

    // Special handling for this, target, @this, @target, @annotation
    // in Spring - we can optimize since we know we have exactly this class,
    // and there will never be matching subclass at runtime.
    if (shadowMatch.alwaysMatches()) {
        return true;
    } else if (shadowMatch.neverMatches()) {
        return false;
    } else {
        // the maybe case
        if (beanHasIntroductions) {
            return true;
        }
        // A match test returned maybe - if there are any subtype sensitive variables
        // involved in the test (this, target, at_this, at_target, at_annotation) then
        // we say this is not a match as in Spring there will never be a different
        // runtime subtype.
        RuntimeTestWalker walker = getRuntimeTestWalker(shadowMatch);
        return (!walker.testsSubtypeSensitiveVars()
                || (targetClass != null && walker.testTargetInstanceOfResidue(targetClass)));
    }
}
