Detailed Description

template<class Adaptee>
class TAO_ESF_Busy_Lock_Adapter< Adaptee >

Adapt classes that implement the "busy lock" protocol, to conform /// to the ACE Lock interface.

The ACE Lock interface allows us to use any mutex-like object with the ACE synchronization components (such as guards, Lock_Adapter, etc.). One of the synchronization protocols used in the event services uses the following protocol:

To acquire the lock the busy method of the object is invoked.
To release the lock the idle method of the object is invoked.
Any changes performed while the lock is held are delayed until all the locks are released, i.e. the last call to idle executes the changes.
