public interface Pointcut

Core pointcut abstraction.

A pointcut is composed of a ClassFilter and a MethodMatcher. Both these basic terms and a Pointcut itself can be combined to build up combinations (e.g. through ComposablePointcut).

TRUE

static final Pointcut TRUE

Canonical Pointcut instance that always matches.

SETTERS

static final Pointcut SETTERS

Pointcut matching all bean property setters, in any class.

GETTERS

static final Pointcut GETTERS

Pointcut matching all bean property getters, in any class.

方法详细资料

getClassFilter

ClassFilter getClassFilter()

Return the ClassFilter for this pointcut.

返回:

the ClassFilter (never null)

getMethodMatcher

MethodMatcher getMethodMatcher()

Return the MethodMatcher for this pointcut.

返回:

the MethodMatcher (never null)

union

static Pointcut union(Pointcut pc1,
 Pointcut pc2)

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

参数:

pc1 - the first Pointcut

pc2 - the second Pointcut

返回:

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

intersection

static Pointcut intersection(Pointcut pc1,
 Pointcut pc2)

Match all methods that both the given pointcuts match.

参数:

pc1 - the first Pointcut

pc2 - the second Pointcut

返回:

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

matches

static boolean matches(Pointcut pointcut,
 MethodInvocation invocation)

Perform the least expensive check for a pointcut match.

参数:

pointcut - the pointcut to match

invocation - runtime invocation contains the candidate method and target class, arguments to the method

返回:

whether there's a runtime match

matches

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

参数:

pointcut - the pointcut to match

method - the candidate method

targetClass - the target class

args - arguments to the method

返回:

whether there's a runtime match
