Method Detail

isRuntime

public 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(Method method,
                       Class targetClass)

Description copied from interface: MethodMatcher

Perform static checking. If this returns false, or if the isRuntime() method returns false, no runtime check will be made.

Specified by:

matches in interface MethodMatcher

Parameters:

method - the 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

matches

public boolean matches(Method method,
                       Class targetClass,
                       Object[] args)

Description copied from interface: MethodMatcher

Is there a runtime (dynamic) match for this method, which must have matched statically. This method is invoked only if the 2-arg matches method returns true for the given method and target class, and if the isRuntime() method returns true. Invoked immediately before potentially running of the advice, after any advice earlier in the advice chain has run.

Specified by:

matches in interface MethodMatcher

Parameters:

method - the candidate method

targetClass - target class

args - arguments to the method

Returns:

whether there's a runtime match
