◆ GetClassType()

virtual GeometryType chrono::geometry::ChLineBezier::GetClassType ( ) const

"Virtual" copy constructor (covariant return type).

Get the class type as unique numerical ID (faster than using ChronoRTTI mechanism). Each inherited class must return an unique ID.

Reimplemented from chrono::geometry::ChLine.

The documentation for this class was generated from the following files:
  • /builds/uwsbel/chrono/src/chrono/geometry/ChLineBezier.h
  • /builds/uwsbel/chrono/src/chrono/geometry/ChLineBezier.cpp
