Public Types
using	Object = CDCSegmentTriple
	Type of the object to be analysed.
using	Interface = Filter< CDCSegmentTriple >
	Mark this class as the basic interface.

Public Member Functions
	MCSegmentTripleFilter (bool allowReverse=true)
	Constructor initializing the symmetry flag.
void	exposeParameters (ModuleParamList *moduleParamList, const std::string &prefix) final
	Expose the parameters to a module.
void	initialize () final
	Initialize the before event processing.
Weight	operator() (const CDCSegmentTriple &segmentTriple) final
	Check if the segment triple is aligned in the Monte Carlo track. Signals NAN if not. More...

	Setter for the allow reverse parameter.
void	beginEvent () override
	Signal the beginning of a new event.
bool	needsTruthInformation () final
	Indicates that the filter requires Monte Carlo information.
bool	getAllowReverse () const
	Getter for the allow reverse parameter.
Weight	operator() (const Object *obj)
	Function to evaluate the object. More...
void	beginRun () override
	Receive and dispatch signal for the beginning of a new run.
void	endRun () override
	Receive and dispatch signal for the end of the run.
void	terminate () override

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.
