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 a concise idiom like: `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)

### 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:
    `getMethodMatcher` in interface `Pointcut`
  Returns:
    the MethodMatcher (never `null`)

### equals

    public boolean equals(Object other)

    public String toString()

  Overrides:
    `toString` in class `Object`
