Class Pointcuts

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

public abstract class Pointcuts
extends Object
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.

Author:: Rod Johnson, Juergen Hoeller

Field Summary

static Pointcut GETTERS
          Pointcut matching all bean property getters, in any class

static Pointcut SETTERS
          Pointcut matching all bean property setters, in any class

Constructor Summary

Pointcuts()


Method Summary

static Pointcut intersection(Pointcut pc1, Pointcut pc2)
          Match all methods that both the given pointcuts match.

static boolean matches(Pointcut pointcut, Method method, Class targetClass, Object[] args)
          Perform the least expensive check for a pointcut match.

static Pointcut union(Pointcut pc1, Pointcut pc2)
          Match all methods that either (or both) of the given pointcuts matches.

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
