Long64_t TSeqCollection::Merge ( TCollection * list )

Merge this collection with all collections coming in the input list.

The input list must contain other collections of objects compatible with the ones in this collection and ordered in the same manner. For example, if this collection contains a TH1 object and a tree, all collections in the input list have to contain a histogram and a tree. In case the list contains collections, the objects in the input lists must also be collections with the same structure and number of objects. If some objects inside the collection are instances of a class that do not have a Merge function (like TObjString), rather than merging, a copy of each instance (via a call to Clone) is appended to the output.

Example

  this                          list
____________                  ---------------------|
| A (TH1F) |  __________      | L1 (TSeqCollection)|- [A1, B1(C1,D1,E1)]
| B (TList)|-| C (TTree)|     | L1 (TSeqCollection)|- [A2, B2(C2,D2,E2)]
