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 concise idioms like in the following example.

Pointcut pc = new ComposablePointcut()
                      .union(classFilter)
                      .intersection(methodMatcher)
                      .intersection(pointcut);

Constructor Detail

ComposablePointcut

public ComposablePointcut()

Create a default ComposablePointcut, with ClassFilter.TRUE and MethodMatcher.TRUE.

ComposablePointcut

public ComposablePointcut(Pointcut pointcut)

Create a ComposablePointcut based on the given Pointcut.

Parameters:

pointcut - the original Pointcut

ComposablePointcut

public ComposablePointcut(ClassFilter classFilter)

Create a ComposablePointcut for the given ClassFilter, with MethodMatcher.TRUE.

Parameters:

classFilter - the ClassFilter to use

ComposablePointcut

public ComposablePointcut(MethodMatcher methodMatcher)

Create a ComposablePointcut for the given MethodMatcher, with ClassFilter.TRUE.

Parameters:

methodMatcher - the MethodMatcher to use

ComposablePointcut

public ComposablePointcut(ClassFilter classFilter,
                          MethodMatcher methodMatcher)

Create a ComposablePointcut for the given ClassFilter and MethodMatcher.

Parameters:

classFilter - the ClassFilter to use

methodMatcher - the MethodMatcher to use

Method Detail

union

public ComposablePointcut union(ClassFilter other)

Apply a union with the given ClassFilter.

Parameters:

other - the ClassFilter to apply a union with

Returns:

this composable pointcut (for call chaining)

intersection

public ComposablePointcut intersection(ClassFilter other)

Apply an intersection with the given ClassFilter.

Parameters:

other - the ClassFilter to apply an intersection with

Returns:

this composable pointcut (for call chaining)

union

public ComposablePointcut union(MethodMatcher other)

Apply a union with the given MethodMatcher.

Parameters:

other - the MethodMatcher to apply a union with

Returns:

this composable pointcut (for call chaining)

intersection

public ComposablePointcut intersection(MethodMatcher other)

Apply an intersection with the given MethodMatcher.

Parameters:

other - the MethodMatcher to apply an intersection with

Returns:

this composable pointcut (for call chaining)

union

public ComposablePointcut union(Pointcut other)

Apply a union with the given Pointcut.

Note that for a Pointcut union, methods will only match if their original ClassFilter (from the originating Pointcut) matches as well. MethodMatchers and ClassFilters from different Pointcuts will never get interleaved with each other.

Parameters:

other - the Pointcut to apply a union with

Returns:

this composable pointcut (for call chaining)

intersection

public ComposablePointcut intersection(Pointcut other)

Apply an intersection with the given Pointcut.

Parameters:

other - the Pointcut to apply an intersection with

Returns:

this composable pointcut (for call chaining)
