m_container

BaseConstPointer ElementLink< TrackParticleBaseCollection >::m_container

mutableprivateinherited

Cached pointer to the container.

Definition at line 197 of file A/AthLinks/ElementLink.h.

m_element

ElementType ElementLink< TrackParticleBaseCollection >::m_element

mutableprivateinherited

Cached pointer to the object.

Definition at line 199 of file A/AthLinks/ElementLink.h.

m_elementCached

bool ElementLink< TrackParticleBaseCollection >::m_elementCached

mutableprivateinherited

Status of the cached pointer.

Definition at line 201 of file A/AthLinks/ElementLink.h.

m_event

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

privateinherited

Pointer to the event object.

Definition at line 203 of file A/AthLinks/ElementLink.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.
