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

---

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

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
