Detailed Description

Element link to XAOD TrackParticle.

An EDM object to reduce dependencies among Tracking/InDet/XAOD domains. This is NOT an analysis class. This link keeps the EDM of different domains together and makes it interchangeable. WARNING: Do not use this class unless you understand how the ITrackLink functions.

A hack to the EDM which will be possibly removed at later stages Kiril.nosp@m.l.Pr.nosp@m.okofi.nosp@m.ev@c.nosp@m.ern.c.nosp@m.h

sg	Associated store.

Returns: True if the link was changed.

If the link is already set, this will return false and leave the link unchanged.

If sg is 0, then we take the store from whatever the link's currently set to. If the link has no current store, then we take the global default.

◆ toIndexedElement() [5/6]

bool ElementLinkBase::toIndexedElement	(	const_pointer_t	obj,
		CLID	link_clid,
		index_type	elemID,
		IProxyDict *	sg )

protectedinherited

Set the link to an element given by index and pointer to container.

Parameters

obj	Pointer to the container (storable).
link_clid	CLID of the link being set.
elemID	The index of the element within the container.
sg	Associated store.

Returns: True if the link was changed.

If the link is already set, this will return false and leave the link unchanged.

If sg is 0, then we take the store from whatever the link's currently set to. If the link has no current store, then we take the global default.

◆ toIndexedElement() [6/6]

bool ElementLinkBase::toIndexedElement	(	const_pointer_t	obj,
		CLID	link_clid,
		index_type	elemID,
		IProxyDict *	sg )

protectedinherited

Set the link to an element given by index and pointer to container.

Parameters

obj	Pointer to the container (storable).
link_clid	CLID of the link being set.
elemID	The index of the element within the container.
sg	Associated store.

Returns: True if the link was changed.

If the link is already set, this will return false and leave the link unchanged.

If sg is 0, then we take the store from whatever the link's currently set to. If the link has no current store, then we take the global default.

◆ toPersistent()

bool ElementLink< xAOD::TrackParticleContainer >::toPersistent ( )

inlineinherited

Dummy function provinding the offline interface.

186{ return true; }

◆ toTransient() [1/3]

virtual bool ElementLink< xAOD::TrackParticleContainer >::toTransient ( )

privatevirtualinherited

Reset the object's internal cache.

Implements ElementLinkBase.

◆ toTransient() [2/3]

bool ElementLinkBase::toTransient ( IProxyDict * sg = 0 )

inherited

Finish initialization after link has been read.

Parameters

sg	Associated store.

This should be called after a link has been read by root in order to set the proxy pointer. Returns true.

If sg is 0, then we use the global default store.

◆ toTransient() [3/3]

bool SG::GenericElementLinkBase< IndexingPolicy >::toTransient ( IProxyDict * sg = 0 )

inherited

Finish initialization after link has been read.

Parameters

sg	Associated store.

This should be called after a link has been read by root in order to set the proxy pointer. Returns true.

If sg is 0, then we use the global default store.

◆ m_event

xAOD::TVirtualEvent* ElementLink< xAOD::TrackParticleContainer >::m_event

◆ m_index

stored_index_type SG::GenericElementLinkBase< IndexingPolicy >::m_index

privateinherited

The index of the element within the container for this link.

Definition at line 538 of file GenericElementLinkBase.h.

◆ m_isDirectIO

bool ElementLinkBase::m_isDirectIO

protectedinherited

A transient variable signalling when direct I/O is happening.

This flag is used exclusively by the ElementLink<>::toTransient() function to know when it should take the persistent data stored in this object into account. That function may be called in normal P->T conversions as well, in which case using the data from this class would just reset the object to its default state.
