exposeParameters()

void exposeParameters ( ModuleParamList *  moduleParamList, const std::string &  prefix  )

virtualinherited

Expose the set of parameters of the filter to the module parameter list.

Note that not all filters have yet exposed their parameters in this way.

This method is deprecated as the exposeParams below uses a less compile heavy equivalent.

operator()() [1/2]

Weight operator() ( const BasePXDStateFilter::Object &  obj )

overridevirtual

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.

Reimplemented from Filter< AObject >.

operator()() [2/2]

Weight operator() ( const Object *  obj )

inherited

Function to evaluate the object.

Base implementation accepts all objects, except nullptr.

Parameters

obj	The 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.
