Declare a new Gaudi property.

Parameters

name	Name of the property.
property	Object holding the property value.

◆ getEGammaTEType()

xAOD::Type::ObjectType Trig::IParticleRetrievalTool::getEGammaTEType ( const HLT::TriggerElement * te ) const

Get the type of particle that should be retrieved from this TE.

Parameters

egammaTE The TE to query

Returns: The type of object that caused this TE to fire.

This function should only be called on a TE from a single leg of an EGamma trigger.

Definition at line 226 of file IParticleRetrievalTool.cxx.

◆ 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.

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.

Definition at line 119 of file AsgTool.cxx.

                                                     {

       // In case we use @c xAOD::TEvent, we have a direct function call
       // for this.
       return evtStore()->event()->getKey( ptr );
 #else
       const SG::DataProxy* proxy = evtStore()->proxy( ptr );
       return ( proxy == nullptr ? 0 : proxy->sgkey() );
 #endif // XAOD_STANDALONE
    }

◆ getName()

const std::string & asg::AsgTool::getName ( const void * ptr ) const

inherited

Get the name of an object that is / should be in the event store.

This is a bit of a special one. StoreGateSvc and xAOD::TEvent both provide ways for getting the std::string name 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::getKey

Parameters

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

Returns: The string name of the object in the store. If not found, an empty string.

                                                             {

   }

◆ msg_level_name()

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

inherited

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

Definition at line 101 of file AsgTool.cxx.

Retrieve the particles that caused this trigger to fire.

Parameters

[out]	combinations	All combinations of particles that could have caused the trigger to fire.
	chain	The name of the chain.
	rerun	Whether to look at the chain in 'rerun' mode. The provided vector will be cleared before use! Note that this also only returns electrons, photons, muons, taus or (for egamma etcut triggers) calo clusters. This tool will not return (b-)jets. For combined (b-)jet+X triggers (where X is one of the above) only the X will be returned. This tool may not work if too much trigger information has been removed.

Perform system initialization for an algorithm.

We override this to declare all the elements of handle key arrays at the end of initialization. See comments on updateVHKA.

Reimplemented in DerivationFramework::CfAthAlgTool, AthCheckedComponent< AthAlgTool >, AthCheckedComponent<::AthAlgTool >, and asg::AsgMetadataTool.

◆ sysStart()

Handle START transition.

We override this in order to make sure that conditions handle keys can cache a pointer to the conditions container.
