Method Detail

init

protected void init(Configuration config,
                    org.apache.activemq.artemis.core.io.IOCriticalErrorListener criticalErrorListener)

Description copied from class: AbstractJournalStorageManager

Called during initialization. Used by implementations to setup Journals, Stores etc...

Overrides:

init in class JournalStorageManager

stop

public void stop(boolean ioCriticalError)
          throws Exception

Specified by:

stop in interface StorageManager

Overrides:

stop in class JournalStorageManager

Parameters:

ioCriticalError - is the server being stopped due to an IO critical error

Throws:

Exception

allocateDirectBuffer

public ByteBuffer allocateDirectBuffer(int size)

Description copied from interface: StorageManager

AIO has an optimized buffer which has a method to release it instead of the way NIO will release data based on GC. These methods will use that buffer if the inner method supports it

Specified by:

allocateDirectBuffer in interface StorageManager

Overrides:

allocateDirectBuffer in class JournalStorageManager

freeDirectBuffer

public void freeDirectBuffer(ByteBuffer buffer)

Description copied from interface: StorageManager

AIO has an optimized buffer which has a method to release it instead of the way NIO will release data based on GC. These methods will use that buffer if the inner method supports it

Specified by:

freeDirectBuffer in interface StorageManager

Overrides:

freeDirectBuffer in class JournalStorageManager
