docs: Returns a dictionary of sink methods found on this object,
          keyed on method name. Sink methods are identified by
          (self, context) arguments on this object. For example:
  
          def f(self, context):
              ...
  
          is a sink method, but
  
          def f(self, ctx):
              ...
  
          is not.
