GetJGeometry()

JGeometry * JGeometryManager::GetJGeometry

(

unsigned int

run_number

)

Return a pointer a JGeometry object that is valid for the given run number.

This first searches through the list of existing JGeometry objects created by this JApplication object to see if it already has the right one. If so, a pointer to it is returned. If not, a new JGeometry object is created and added to the internal list. Note that since we need to make sure the list is not modified by one thread while being searched by another, a mutex is locked while searching the list. It is NOT efficient to get the JGeometry object pointer every event. Factories should get a copy in their brun() callback and keep a local copy of the pointer for use in the evnt() callback.
