public abstract class DynamicMethodMatcher

extends java.lang.Object

implements MethodMatcher

Convenient abstract superclass for dynamic method matchers, which do care about arguments at runtime.

Method Summary

boolean	isRuntime() Is this MethodMatcher dynamic? Must a final call be made on the matches(Method, Class, Object[]) method at runtime even if the 2-arg matches method returns true? Can be invoked when an AOP proxy is created, and need not be invoked again before each method invocation,
boolean	matches(java.lang.reflect.Method m, java.lang.Class targetClass) Can override to add preconditions for dynamic matching.

Method Detail

isRuntime

public final boolean isRuntime()

Description copied from interface: MethodMatcher

Is this MethodMatcher dynamic? Must a final call be made on the matches(Method, Class, Object[]) method at runtime even if the 2-arg matches method returns true? Can be invoked when an AOP proxy is created, and need not be invoked again before each method invocation,

Note: Could be pulled up into a Matcher super-interface to apply to fields also.

Specified by:

isRuntime in interface MethodMatcher

Returns:

whether or not a runtime matche via the 3-arg matches() method is required if static matching passed.

matches

public boolean matches(java.lang.reflect.Method m,
                       java.lang.Class targetClass)

Can override to add preconditions for dynamic matching. This implementation always returns true.

Specified by:

matches in interface MethodMatcher

Parameters:

m - candidate method

targetClass - 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
