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);

  • Method Details

    • 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)

    • getClassFilter

      public ClassFilter getClassFilter()
      Description copied from interface: Pointcut
      Return the ClassFilter for this pointcut.
      Specified by:
      getClassFilter in interface Pointcut
      Returns:
      the ClassFilter (never null)

    • getMethodMatcher

      public MethodMatcher getMethodMatcher()
      Description copied from interface: Pointcut
      Return the MethodMatcher for this pointcut.
      Specified by:
