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.

See also

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.

msg_level_name()

const std::string & asg::AsgTool::msg_level_name ( ) const

A deprecated function for getting the message level's name.

Instead of using this, weirdly named function, user code should get the string name of the current minimum message level (in case they really need it...), with:

MSG::name( msg().level() )

This function's name doesn't follow the ATLAS coding rules, and as such will be removed in the not too distant future.

Returns

The string name of the current minimum message level that's printed
