AdvanceFilter< AState, AnAdvancer > Class Template Reference

Filter which can be used on a pair of path (vector of states) and states, which will call the extrapolate function of the given advancer class, to extrapolate the last path state to the plane of the new state and store the mSoP in the new state. More...

Detailed Description

template<class AState, class AnAdvancer>
class Belle2::AdvanceFilter< AState, AnAdvancer >

Filter which can be used on a pair of path (vector of states) and states, which will call the extrapolate function of the given advancer class, to extrapolate the last path state to the plane of the new state and store the mSoP in the new state.

Will return the result of the advancers extrapolation function as a filter result or NAN of the extrapolation throws a genfit::Exception.

Template Parameters

AState	should have the basic functionality of a CKFState.
AnAdvancer	The class to be used during extrapolation. Should have the functions: exposeParameters(moduleParamList, prefix) setMaterialEffectsToParameterValue() extrapolateToPlane(mSoP, plane) resetMaterialEffects() should be a ProcessingSignalListener.

Member Function Documentation

operator()() [1/2]

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.

Definition at line 66 of file Filter.icc.h.

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.
