## org.springframework.aop.support
Class AbstractRegexpMethodPointcut

    java.lang.Object
      org.springframework.aop.support.StaticMethodMatcher
          org.springframework.aop.support.StaticMethodMatcherPointcut
              org.springframework.aop.support.AbstractRegexpMethodPointcut

All Implemented Interfaces:
  Serializable, MethodMatcher, Pointcut

Direct Known Subclasses:
  JdkRegexpMethodPointcut, Perl5RegexpMethodPointcut

    public abstract class AbstractRegexpMethodPointcut

extends StaticMethodMatcherPointcut
implements Serializable

Abstract base regular expression pointcut bean. JavaBean properties are:

- pattern: regular expression for the fully-qualified method names to match. The exact regexp syntax will depend on the subclass (e.g. Perl5 regular expressions)
- patterns: alternative property taking a String array of patterns. The result will be the union of these patterns.

Note: the regular expressions must be a match. For example, `.*get.*` will match com.mycom.Foo.getBar(). `get.*` will not.

This base class is serializable. Subclasses should declare all fields transient - the initPatternRepresentation method in this class will be invoked again on the client side on deserialization.

Since:
  1.1

Constructor Detail

### AbstractRegexpMethodPointcut

    public AbstractRegexpMethodPointcut()

Method Detail

### setPattern

    public void setPattern(String pattern)

  Convenience method when we have only a single pattern. Use either this method or `setPatterns(java.lang.String[])`, not both.

  See Also:
    `setPatterns(java.lang.String[])`

### setPatterns

    public void setPatterns(String[] patterns)

  Set the regular expressions defining methods to match. Matching will be the union of all these; if any match, the pointcut matches.

### getPatterns

    public String[] getPatterns()

  Return the regular expressions for method matching.

### setExcludedPattern

    public void setExcludedPattern(String excludedPattern)

  Convenience method when we have only a single exclusion pattern. Use either this method or `setExcludedPatterns(java.lang.String[])`, not both.

  See Also:
    `setExcludedPatterns(java.lang.String[])`

### setExcludedPatterns

    public void setExcludedPatterns(String[] excludedPatterns)

  Set the regular expressions defining methods to match for exclusion. Matching will be the union of all these; if any match, the pointcut matches.

### getExcludedPatterns

    public String[] getExcludedPatterns()

  Returns the regular expressions for exclusion matching.

### matches

    public final boolean matches(Method method,
                                 Class targetClass)

  Try to match the regular expression against the fully qualified name of the method's declaring class, plus the name of the method. Note that the declaring class is that class that originally declared the method, not necessarily the class that's currently exposing it.

  For example, "java.lang.Object.hashCode" matches any subclass of Object's `hashCode()` method.

  Specified by:
    `matches` in interface `MethodMatcher`
  Parameters:
    `method` - the candidate method
    `targetClass` - the target class (may be `null`, in which case the candidate class must be taken to be the method's declaring class)
  Returns:
    whether or not this method matches statically

### initPatternRepresentation

    protected abstract void initPatternRepresentation(String[] patterns)
                                               throws IllegalArgumentException

  Subclasses must implement this to initialize regexp pointcuts. Can be invoked multiple times.

  This method will be invoked from the setPatterns method, and also on deserialization.

  Parameters:
    `patterns` - the patterns to initialize
  Throws:
    `IllegalArgumentException` - in case of an invalid pattern

### initExcludedPatternRepresentation

    protected abstract void initExcludedPatternRepresentation(String[] excludedPatterns)
                                                       throws IllegalArgumentException

  Throws:
    `IllegalArgumentException`

### matches

    protected abstract boolean matches(String pattern,
                                       int patternIndex)

  Does the pattern at the given index match this string?

  Parameters:
    `pattern` - `String` pattern to match
    `patternIndex` - index of pattern from 0
  Returns:
    `true` if there is a match, else `false`.

### matchesExclusion

    protected abstract boolean matchesExclusion(String pattern,
                                                int patternIndex)

  Does the exclusion pattern at the given index match this string?

  Parameters:
    `pattern` - `String` pattern to match.
    `patternIndex` - index of pattern starting from 0.
  Returns:
    `true` if there is a match, else `false`.

### equals

    public boolean equals(Object other)

  Overrides:
    `equals` in class `Object`

### hashCode

    public int hashCode()

  Overrides:
    `hashCode` in class `Object`

### toString

    public String toString()

  Overrides:
    `toString` in class `Object`
