Public Member Functions

 MVAFeasibleTrackRelationFilter ()
 Constructor initialising the MVAFilter with standard training name for this filter.
 
void exposeParameters (ModuleParamList *moduleParamList, const std::string &prefix) override
 Expose the set of parameters of the filter to the module parameter list.
 
void initialize () override
 Initialize the expert before event processing.
 
void beginRun () override
 Signal to load new run parameters.
 
Weight operator() (const Object &obj) override
 Function to object for its signalness.

Member Function Documentation

◆ operator()() [1/3]

virtual Weight operator() ( const AObject &  from,
const AObject &  to 
)
virtualinherited

Main filter method returning the weight of the neighborhood relation.

Return always returns NAN to reject all segment neighbors.

◆ operator()() [2/3]

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.

Definition at line 60 of file Filter.icc.h.

◆ operator()() [3/3]

Weight operator() ( const Relation< AObject > &  relation)
overrideinherited

Main filter method overriding the filter interface method.

Checks the validity of the pointers in the relation and unpacks the relation to the method implementing the rejection.
