Standard constructor.
Parameters:

| ClassMap | | public ClassMap(Class aClass)(Code) | | Standard constructor.
Parameters:
aClass - the class to deconstruct. |
| findMethod | | public Method findMethod(String name, Object[] params) throws MethodMap.AmbiguousException(Code) | | 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 name
Parameters:
params - method parameters CACHE_MISS or a Method
throws:
MethodMap.AmbiguousException - if the method and parameters are ambiguous. |
| getCachedClass | | Class getCachedClass()(Code) | | the class object whose methods are cached by this map. |
| getPublicMethod | | public static Method getPublicMethod(Method method)(Code) | | 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. the publicly callable counterpart method. Note that if theparameter method is itself declared by a public class, thismethod is an identity function. |
