Detailed Description

AlgoTool calculates the points of minimum distance between two tracks on the transverse plane, which is analytically well defined (intersection of two circles). In case of double intersection different possibilities were considered; at the end I found reasonably good to choose the intersection point where the tracks are nearest in the z coordinate...

changes: 11-11-2007 Intersection case completely rewritten after having done analytical calculation (sign come out of calculation!)

Parameters

hndlObject holding the property value.
docDocumentation string for the property.

This is the version for types that derive from SG::VarHandleBase. The property value object is put on the input and output lists as appropriate; then we forward to the base class.

inlineinherited

Declare a new Gaudi property.

Parameters
nameName of the property.
propertyObject holding the property value.
docDocumentation string for the property.

This is the generic version, for types that do not derive from SG::VarHandleKey. It just forwards to the base class version of declareProperty.

)

Declare a new Gaudi property.

Parameters
nameName of the property.
propertyObject holding the property value.

This dispatches to either the generic declareProperty or the one for VarHandle/Key/KeyArray.
