Detailed Description

This interface represents APC framework gateway. It provides functionality used for protecting data that usually is being accessed by many reading threads and few writing threads. It allows access to protecting data simultaneously by reading threads until no thread gains write access. Corresponding C++ library: TD_DbRoot <group OdApc_Classes>

Member Function Documentation

enter()

virtual void OdApcDataReadWriteDispatcher::enter ( )

pure virtual

A calling thread waits until area is unlocked and enters it to read only.

leave()

virtual void OdApcDataReadWriteDispatcher::leave ( )

pure virtual

A calling thread leaves protected area.

lock()

virtual void OdApcDataReadWriteDispatcher::lock ( )

pure virtual

1. Locks the entrance.
2. Waits until all threads exit read state.
3. Returns.

   Remarks

   IMPORTANT: If calling thread calls enter() without leave(), it should call lockFromInside() to be not deadlocked.

lockFromInside()

virtual void OdApcDataReadWriteDispatcher::lockFromInside ( )

pure virtual

Locks the entrance while being in read state.

Remarks

To unlock protected area, the calling thread may either call unlock() or unlockFromInside() to stay in read state.

unlock()

virtual void OdApcDataReadWriteDispatcher::unlock ( )

pure virtual

Unlocks the entrance.

unlockFromInside()

virtual void OdApcDataReadWriteDispatcher::unlockFromInside ( )

pure virtual

Unlocks the entrance while staying in read state.
