Examples with MethodMatcher org.springframework.aop.MethodMatcher used on opensource projects

Example 1 with MethodMatcher

use of org.springframework.aop.MethodMatcher in project spring-framework by spring-projects.

the class AopUtils method canApply.

/**
	 * Can the given pointcut apply at all on the given class?
	 * <p>This is an important test as it can be used to optimize
	 * out a pointcut for a class.
	 * @param pc the static or dynamic pointcut to check
	 * @param targetClass the class to test
	 * @param hasIntroductions whether or not the advisor chain
	 * for this bean includes any introductions
	 * @return whether the pointcut can apply on any method
	 */

    }
    MethodMatcher methodMatcher = pc.getMethodMatcher();
    if (methodMatcher == MethodMatcher.TRUE) {
        // No need to iterate the methods if we're matching any method anyway...
