Member Function Documentation

◆ operator()() [1/2]

◆ operator()() [2/2]

Weight operator() ( const Object obj)
inherited

Function to evaluate the object.

Base implementation accepts all objects, except nullptr.

Parameters
objThe object to be accepted or rejected.
Returns
A finit float value if the object is accepted. NAN if the object is rejected. Nullptr is always rejected.
