Muon digit container status: user interface

The current proposal is a three-level structure:

• 1. Each muon technology (MDT, CSC, RPC, TGC) has its own container.

• 2. Each technology container provides access to subcontainers holding all the digits in a module (chamber). This access is keyed by module identifier.

• 3. Iterators provide access to digits in a module subcontainer.

Example (actual syntax may vary):

  MdtContainer mdt_digits;
  MdtModuleId id("7/BIL/-3/5/MDT");
  MdtModuleContainer mod_digits = mdt_digits.fetch(id);
  for ( MdtModuleContainer::const_iterator idig = mdt_digits.begin();
        idig!=mdt_digits.end(); ++idig ) {
    cout << *idig << endl;
  }

Do our present identifiers specify chambers?

This granularity may not be and likely is not the same as that of the persistent storage.

The implementation (including the layout of the persistent storage) is not exposed by the interface.
