## Detailed Description

Specialized output stream class for event tag collections, where the basic Event entry point should be placed as well into the collection itself.

The TagCollectionStream is a rather specialized object combining features of NTuple I/O and object I/O. The main working points are:

1) Write a "normal" tag collection. The address column [property AddressColumn, default:"Address"] is added to the Ntuple identified by its name [mandatory property Collection]. The address column is set to the opaque address of the specified leaf [property "AddressLeaf", default:"/Event"]. The NTuple must be registered to the TES of the service [property: TagCollectionSvc, default:"NTupleSvc"]. This is the normal mode event tag collections work.

2) Write a tag collection with "REDIRECTED INPUT". Example: The collection is created from an intermediate file (MINI DST), but the Address column of the NTuple should point to the file e.g. containing the raw data.

- Set the property "AddressLeaf" to something different from "/Event" e.g. "/Event/DAQ/RawEvent"

Note: The actual address of "/Event" get changed. No other output should be created after writing such a tag collection.

3) Write an "EMBEDDED COLLECTION". In this mode the OutputStream and the NTuple stream are combined. depending on the property TagCollectionStream.ObjectsFirst the objects are written first and the the tags. The tag file and the file containing the objects may be identical.

Note:

- Also if the OutputStream features are NOT used, the options must still be properly set.
- Tags or objects are only written to the output stream if the event is accepted according to the output stream criteria (veto algorithms, etc.)
- If the address column is not present in the N-tuple (ie. it was not added by the N-tuple creator), it is automatically added at the first write attempt.
- If the logical N-tuple output file is not yet connected to the tuple service, it is automatically connected to the the same as the OutputStream device.
