| bool | m_isDirectIO |
A base class holding the container independent part of ElementLink.
For technical reasons it's a good idea to define a common base class for the ElementLink classes, it helps with ROOT I/O immensely.
bool ElementLinkBase::m_isDirectIO [protected] |
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.
