Detailed Description

Work around MCTruthClassifier brain-damage.

This avoids having to specify the container names during configuration.

MCTruthClassifier requires specifying, at configuration time, the names of the TrackParticleContainer and TrackParticleTruthCollection objects to use for the mapping. This is painful in for electrons in the case where one may have several different track containers.

What we do to make this easier is to search through SG to find a truth collection that points at the TrackParticleContainer that contains the tracks for the electron we're looking at.

getKey()

SG::sgkey_t asg::AsgTool::getKey ( const void *  ptr ) const

inherited

Get the (hashed) key of an object that is in the event store.

This is a bit of a special one. StoreGateSvc and xAOD::TEvent both provide ways for getting the SG::sgkey_t key for an object that is in the store, based on a bare pointer. But they provide different interfaces for doing so.

In order to allow tools to efficiently perform this operation, they can use this helper function.

asg::AsgTool::getName

Parameters

ptr	The bare pointer to the object that the event store should know about

Returns

The hashed key of the object in the store. If not found, an invalid (zero) key.
