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.

If this index engine supports a more narrow locking, for example key-based sharding, it may use the provided key to infer a more narrow lock scope, but that is not a requirement.

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.

getIndexNameByKey

public String getIndexNameByKey(Object key)

Specified by:

getIndexNameByKey in interface OBaseIndexEngine

freeze

public void freeze(boolean throwException)

Description copied from interface: OFreezableStorageComponent

After this method finished it's execution, all threads that are going to perform data modifications in storage should wait till OFreezableStorageComponent.release() method will be called. This method will wait till all ongoing modifications will be finished.

Specified by:

freeze in interface OFreezableStorageComponent

Parameters:

throwException - If true OModificationOperationProhibitedException exception will be thrown on call of methods that requires storage modification. Otherwise other threads will wait for OFreezableStorageComponent.release() method call.

release

public void release()

Description copied from interface: OFreezableStorageComponent

After this method finished execution all threads that are waiting to perform data modifications in storage will be awaken and will be allowed to continue their execution.

Specified by:

release in interface OFreezableStorageComponent
