Detailed Description

Class to handle the services needed by the muon reconstruction This class avoid the EventSetup percolation. The update method is called each event in order to update the pointers.

◆ eventSetup()

const edm::EventSetup& MuonServiceProxy::eventSetup ( ) const

inline

get the whole EventSetup (Note: this is a dangerous function. I would delete it if modules were not using it. If this function is called for an event where the function 'update' was not called, then the pointer stored in 'theEventSetup' will point to an object that no longer exists even if all the ESHandles are still valid! Be careful. As long as 'update' is called every event and this is only used while processing that single corresponding event, it will work OK... This function also makes it difficult to examine code in a module and understand which parts of a module use the EventSetup to get data.)
