PointStreamXYZXYZHandlerBase Class

Base class for handling points in pairs.

  • Callers implement handleXYZXYZ to receive point pairs.
  • Callers may implement startChain and endChain.
    • Beware that if startChain is implemented it must call super.startChain () to reset internal x0, y0,z0 to undefined.
    • If that is not done, a point pair will appear from the end of previous chain to start of new chain.
    • This (intermediate base) class does NOT override startChain
