Detailed Description

Interface to allow an object to lock itself when made const in SG.

An object recorded in StoreGate can be ‘locked’ by a call to StoreGateSvc::setConst(). Normally, this just sets a flag in the DataProxy, which tells StoreGate not to allow non-const retrieves. However, sometimes the object itself should know about this; for example, when a container with an auxiliary store is locked. If an object in StoreGate derives from ILockable, then a setConst() operation will call lock() on the object.

Member Function Documentation

lock()

virtual void ILockable::lock ( )

pure virtual

Lock this object.

When an object in StoreGate is locked via StoreGateSvc::setConst, StoreGate will call this method on the object, provided the object derives from ILockable.
