void 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, ViewBase, CutPlotter, TextPlotter, BinningProjector, DyHist1DProjector, DyHist2DProjector, NTupleProjector, Profile2DProjector, ProfileProjector, and RootController.
