Class ComposablePointcut

java.lang.Object
  org.springframework.aop.support.ComposablePointcut

All Implemented Interfaces:

Serializable, Pointcut

public class ComposablePointcut
extends Object
implements Pointcut, Serializable

Convenient class for building up pointcuts. All methods return ComposablePointcut, so we can use a concise idiom like: Pointcut pc = new ComposablePointcut().union(classFilter).intersection(methodMatcher).intersection(pointcut);

There is no union(Pointcut, Pointcut) method on this class. Use the Pointcuts.union method for this.
