Detailed Description

A wrapper class for Observer to allow its pure virtual function to be implemented in Python.

Note:

This class needs Python 2.3 or later to be fully functional.

Member Function Documentation

void ObserverWrap::update (  const Observable *  obs  )  [virtual]

Note: This function is only available with Python 2.3 or later. Implements hippodraw::Observer. Definition at line 58 of file ObserverWrap.cxx. References m_self.

void hippodraw::Observer::willDelete (  const Observable *   )  [virtual, inherited]

Notifies this Observer object that one of its Observable objects is about to be deleted. Since most Observable objects are owned by its Observer, it is the Observer that issued the delete. Thus the default implementation here does nothing. Derived classes that observe objects owned by another should implement this method to remove the Observable from the list they are observing. Reimplemented in FunctionRep, DataSourceController, CutPlotter, TextPlotter, BinningProjector, DyHist1DProjector, DyHist2DProjector, NTupleProjector, Profile2DProjector, and ProfileProjector.
