NullGeometryHandler Class

NullGeometryHandler is a base class for dispatching various geometry types to application specific implementation of some service.

To use:

  • Derive a class from NullGeometryHandler
  • Reimplement any or all of the specific handleXXXX methods
  • Create a handler instance myHandler
  • To send a GeometryQuery object candidateGeometry through the (fast) dispatch, invoke `candidateGeometry.dispatchToHandler (myHandler)
  • The appropriate method or methods will get called with a strongly typed _g value.
