findMethod
public Method findMethod(String name,
Object[] params)
throws MethodMap.AmbiguousException
- Find a Method using the methodKey provided.
Look in the methodMap for an entry. If found, it'll either be a
CACHE_MISS, in which case we simply give up, or it'll be a Method, in
which case, we return it.
If nothing is found, then we must actually go and introspect the method
from the MethodMap.
- Parameters:
name
- method nameparams
- method parameters- Returns:
- CACHE_MISS or a
Method
- Throws:
MethodMap.AmbiguousException
- if the method and parameters are ambiguous.
getPublicMethod
public static Method getPublicMethod(Method method)
- For a given method, retrieves its publicly accessible counterpart. This
method will look for a method with same name and signature declared in a
public superclass or implemented interface of this method's declaring
class. This counterpart method is publicly callable.
- Parameters:
method
- a method whose publicly callable counterpart is requested.- Returns:
- the publicly callable counterpart method. Note that if the
parameter method is itself declared by a public class, this
method is an identity function.
