Method Detail

isRuntime

public final boolean isRuntime()

Description copied from interface: MethodMatcher

Is this MethodMatcher dynamic, that is, must a final call be made on the MethodMatcher.matches(java.lang.reflect.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,

Specified by:

isRuntime in interface MethodMatcher

Returns:

whether or not a runtime match via the 3-arg MethodMatcher.matches(java.lang.reflect.Method, Class, Object[]) method is required if static matching passed

matches

public boolean matches(Method method,
                       @Nullable
                       Class<?> targetClass)

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

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
