Method Detail

setCloseable

public void setCloseable(AutoCloseable closeable)

getIdentifier

public final String getIdentifier()

Specified by:

getIdentifier in interface org.opendaylight.yangtools.concepts.Identifiable<String>

newReadOnlyTransaction

public DOMStoreReadTransaction newReadOnlyTransaction()

Description copied from interface: DOMStoreTransactionFactory

Creates a read only transaction

Creates a new read-only transaction, which provides read access to snapshot of current state. See DOMStoreReadTransaction for more information.

Specified by:

newReadOnlyTransaction in interface DOMStoreTransactionFactory

Returns:

new DOMStoreReadTransaction

newReadWriteTransaction

public DOMStoreReadWriteTransaction newReadWriteTransaction()

Description copied from interface: DOMStoreTransactionFactory

Creates Read-Write transaction

See DOMStoreReadWriteTransaction for more information.

Specified by:

newReadWriteTransaction in interface DOMStoreTransactionFactory

Returns:

new DOMStoreWriteTransaction

newWriteOnlyTransaction

public DOMStoreWriteTransaction newWriteOnlyTransaction()

Description copied from interface: DOMStoreTransactionFactory

Creates write only transaction

See DOMStoreWriteTransaction for more information.

Specified by:

newWriteOnlyTransaction in interface DOMStoreTransactionFactory

Returns:

new DOMStoreWriteTransaction

createTransactionChain

public DOMStoreTransactionChain createTransactionChain()

Description copied from interface: DOMStore

Creates new transaction chain. Transactions in a chain need to be committed in sequence and each transaction should see the effects of previous transactions as if they happened. See DOMStoreTransactionChain for more information.

Specified by:

createTransactionChain in interface DOMStore

Returns:

Newly created transaction chain.

onGlobalContextUpdated

public void onGlobalContextUpdated(org.opendaylight.yangtools.yang.model.api.SchemaContext ctx)

Specified by:

onGlobalContextUpdated in interface org.opendaylight.yangtools.yang.model.api.SchemaContextListener

close

public void close()

Specified by:

close in interface AutoCloseable

getDebugTransactions

public final boolean getDebugTransactions()

registerTreeChangeListener

public <L extends DOMDataTreeChangeListener> org.opendaylight.yangtools.concepts.ListenerRegistration<L> registerTreeChangeListener(org.opendaylight.yangtools.yang.data.api.YangInstanceIdentifier treeId,
                                                                                                                           L listener)

Description copied from interface: DOMStoreTreeChangePublisher

Registers a DOMDataTreeChangeListener to receive notifications when data changes under a given path in the conceptual data tree.

You are able to register for notifications for any node or subtree which can be represented using YangInstanceIdentifier.

You are able to register for data change notifications for a subtree or leaf even if it does not exist. You will receive notification once that node is created.

If there is any pre-existing data in data tree on path for which you are registering, you will receive initial data change event, which will contain all pre-existing data, marked as created.

This method returns a ListenerRegistration object. To "unregister" your listener for changes call the ListenerRegistration.close() method on this returned object.

You MUST explicitly unregister your listener when you no longer want to receive notifications. This is especially true in OSGi environments, where failure to do so during bundle shutdown can lead to stale listeners being still registered.

Specified by:

registerTreeChangeListener in interface DOMStoreTreeChangePublisher

Parameters:

treeId - Data tree identifier of the subtree which should be watched for changes.

listener - Listener instance which is being registered

Returns:

Listener registration object, which may be used to unregister your listener using ListenerRegistration.close() to stop delivery of change events.

transactionAborted

protected void transactionAborted(SnapshotBackedWriteTransaction<String> tx)

Description copied from class: SnapshotBackedWriteTransaction.TransactionReadyPrototype

Called when a transaction is closed without being readied. This is not invoked for transactions which are ready.

Specified by:

transactionAborted in class SnapshotBackedWriteTransaction.TransactionReadyPrototype<String>

Parameters:

tx - Transaction which got aborted.

transactionReady

protected DOMStoreThreePhaseCommitCohort transactionReady(SnapshotBackedWriteTransaction<String> tx,
                                              org.opendaylight.yangtools.yang.data.api.schema.tree.DataTreeModification modification)

Description copied from class: SnapshotBackedWriteTransaction.TransactionReadyPrototype

Returns a commit coordinator associated with supplied transactions. This call must not fail.

Specified by:

transactionReady in class SnapshotBackedWriteTransaction.TransactionReadyPrototype<String>

Parameters:

tx - Transaction on which ready was invoked.

modification - Modified data tree which has been constructed.

Returns:

DOMStoreThreePhaseCommitCohort associated with transaction
