Class 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

        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)
