org.springframework.aop.support.Pointcuts

public abstract class Pointcuts
extends Object

Pointcut constants for matching getters and setters, and static methods useful for manipulating and evaluating pointcuts.

These methods are particularly useful for composing pointcuts using the union and intersection methods.

Method Detail

union

public static Pointcut union(Pointcut pc1,
                             Pointcut pc2)

Match all methods that either (or both) of the given pointcuts matches.

Parameters:

pc1 - the first Pointcut

pc2 - the second Pointcut

Returns:

a distinct Pointcut that matches all methods that either of the given Pointcuts matches

intersection

public static Pointcut intersection(Pointcut pc1,
                                    Pointcut pc2)

Match all methods that both the given pointcuts match.

Parameters:

pc1 - the first Pointcut

pc2 - the second Pointcut

Returns:

a distinct Pointcut that matches all methods that both of the given Pointcuts match

matches

public static boolean matches(Pointcut pointcut,
                              Method method,
                              Class<?> targetClass,
                              Object... args)

Perform the least expensive check for a pointcut match.

Parameters:

pointcut - the pointcut to match

method - the candidate method

targetClass - the target class

args - arguments to the method

Returns:

whether there's a runtime match
