acquireAtomicExclusiveLock

public boolean acquireAtomicExclusiveLock(Object key)

Description copied from interface: OBaseIndexEngine

Acquires exclusive lock in the active atomic operation running on the current thread for this index engine.

Specified by:

acquireAtomicExclusiveLock in interface OBaseIndexEngine

Parameters:

key - the index key to lock.

Returns:

true if this index was locked entirely, false if this index locking is sensitive to the provided key and only some subset of this index was locked.
