KalmanFilter< AState, AKalmanStepper > Class Template Reference

Filter which can be used on a pair of path (vector of states) and states, which will call the kalmanStep function of the given stepper class, to update the mSoP of the new state with a klaman update. More...

Detailed Description

template<class AState, class AKalmanStepper>
class Belle2::KalmanFilter< AState, AKalmanStepper >

Filter which can be used on a pair of path (vector of states) and states, which will call the kalmanStep function of the given stepper class, to update the mSoP of the new state with a klaman update.

Will return the result of the steppers kalmanStep function as a filter result (which should be the chi2) and will also set the chi2 of the new state.

Template Parameters
AStateshould have the basic functionality of a CKFState.
AKalmanSteppershould have a kalmanStep function.

Member Function Documentation

◆ 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.

Reimplemented in AdvanceFilter< AState, AnAdvancer >.

Definition at line 52 of file Filter.icc.h.

◆ operator()() [1/2]

Weight operator() ( const Object obj)
virtualinherited

Function to evaluate the object.

Base implementation accepts all objects.

Parameters
objThe 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
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.
