Detailed Description

Abstract base class for objects that can be merged but also named.

Mostly copied from framework/pcore/Mergeable.h

This is mainly intended to be a base class for custom objects we save via the CAF. We do less TDirectory/TFile management here compared to Mergeable since we aren't using the datastore and don't need to disconnect from TFiles etc. We'll be explicitly managing that in the CAF (see CalibObjManager).

Member Function Documentation

merge()

virtual void merge ( const MergeableNamed *  other )

pure virtual

Merge object 'other' into this one.

Your derived class must implement this function. You can static_cast 'other' to your own type (when called, this and other are guaranteed to point to objects of the same type).

Note that 'other' will be deleted after the merge, so make sure you copy all data from it that you will need.

Implemented in MilleData.

Reset()

virtual void Reset ( )

inlinevirtual

Root-like Reset function for "template compatibility" with ROOT objects.

Alias for clear().

Definition at line 52 of file MergeableNamed.h.

SetDirectory()

virtual void SetDirectory ( TDirectory *  )

inlinevirtual

Root-like Clone function for "template compatibility" with ROOT objects.

Calls clone() Root-like SetDirectory function for "template compatibility" with ROOT objects. Does nothing.
