operator()() [2/7]

virtual Weight operator() ( const Object & obj )

virtualinherited

Function to evaluate the object.

Base implementation accepts all objects.

Parameters

obj	The object to be accepted or rejected.

Returns

A finite float value if the object is accepted. NAN if the object is rejected.
