Detailed Description

Basic working principle: use ThreeHitVariables and provide three B2Vector3D to each variable.

These are oHit (outer hit), cHit (middle hit), and iHit (inner hit) and then calculate the variables specified in ThreeHitVariables for the three positions, often using the difference (oHit - cHit) and (cHit - iHit).

Member Function Documentation

operator()()

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.
