An array of references to TObjects.
The array expands automatically when objects are added (shrinking can be done by hand using Expand() )
The TRefArray can be filled with:
The array elements can be retrieved with:
By default the TRefArray 'points' to the current process and can only receive object that have been created in this process. To point the TRefArray to a different process do:
For example, if 'obj' is an instance that was created in the different process and you do:
Then
is correct (obj comes from the process the array is pointed to while
is incorrect since 'nobj' was created in a different process than the one the array is pointed to. In this case you will see error message:
When a TRefArray is Streamed, only the pointer unique id is written, not the referenced object. TRefArray may be assigned to different branches of one Tree or several Trees. The branch containing the TRefArray can be read before or after the array (eg TClonesArray, STL vector,..) of the referenced objects.
See an example in $ROOTSYS/test/Event.h
Use an array of TRef when one of the above restrictions is met.
The number of TRef handled by a single process id is limited to 16777215 (see TRef for more detail). When the TProcessID is full (has seen 16777215 objects), we switch to new one TProcessID maximum 65535 including the TProcessIDs read from file). However TRefArray can not switch to new TProcessID if they already contain objects.
When the TProcessID has been switched due to overflow and an new object is added to an existing, empty TRefArray, you will see:
If the TRefArray was not empty, you will see:
When running out of TProcessIds, you will see:

Remove object at index idx.
Reimplemented from TSeqCollection.
Definition at line 722 of file TRefArray.cxx.
Set index of last object in array, effectively truncating the array.
Use carefully since whenever last position has to be recalculated, e.g. after a Remove() or Sort() it will be reset to the last non-empty slot. If last is -2 this will force the recalculation of the last used slot.
Definition at line 773 of file TRefArray.cxx.
If objects in array are sortable (i.e.
IsSortable() returns true for all objects) then sort array.
