Method Detail

newReadOnlyTransaction

ReadOnlyTransaction newReadOnlyTransaction()

Deprecated.

Description copied from interface: AsyncDataTransactionFactory

Allocates a new read-only transaction which provides an immutable snapshot of the data tree.

The view of data tree is an immutable snapshot of current data tree state when transaction was allocated.

Specified by:

newReadOnlyTransaction in interface AsyncDataBroker<org.opendaylight.yangtools.yang.binding.InstanceIdentifier<?>,org.opendaylight.yangtools.yang.binding.DataObject>

Specified by:

newReadOnlyTransaction in interface AsyncDataTransactionFactory<org.opendaylight.yangtools.yang.binding.InstanceIdentifier<?>,org.opendaylight.yangtools.yang.binding.DataObject>

Specified by:

newReadOnlyTransaction in interface TransactionFactory

Returns:

new read-only transaction

newReadWriteTransaction

ReadWriteTransaction newReadWriteTransaction()

Deprecated.

Description copied from interface: AsyncDataTransactionFactory

Allocates new read-write transaction which provides a mutable view of the data tree.

Preconditions for mutation of data tree are captured from the snapshot of data tree state, when the transaction is allocated. If data was changed during transaction in an incompatible way then the commit of this transaction will fail. See AsyncWriteTransaction.submit() for more details about conflicting and not-conflicting changes and failure scenarios.

Specified by:

newReadWriteTransaction in interface AsyncDataBroker<org.opendaylight.yangtools.yang.binding.InstanceIdentifier<?>,org.opendaylight.yangtools.yang.binding.DataObject>

Specified by:

newReadWriteTransaction in interface AsyncDataTransactionFactory<org.opendaylight.yangtools.yang.binding.InstanceIdentifier<?>,org.opendaylight.yangtools.yang.binding.DataObject>

Specified by:

newReadWriteTransaction in interface TransactionFactory

Returns:

new read-write transaction

newWriteOnlyTransaction

WriteTransaction newWriteOnlyTransaction()

Deprecated.

Description copied from interface: AsyncDataTransactionFactory

Allocates new write-only transaction based on latest state of data tree.

Preconditions for mutation of data tree are captured from the snapshot of data tree state, when the transaction is allocated. If data was changed during transaction in an incompatible way then the commit of this transaction will fail. See AsyncWriteTransaction.submit() for more details about conflicting and not-conflicting changes and failure scenarios.

Since this transaction does not provide a view of the data it SHOULD BE used only by callers which are exclusive writers (exporters of data) to the subtree they modify. This prevents optimistic lock failures as described in AsyncWriteTransaction.submit().

Exclusivity of writers to particular subtree SHOULD BE enforced by external locking mechanism.

Specified by:

newWriteOnlyTransaction in interface AsyncDataBroker<org.opendaylight.yangtools.yang.binding.InstanceIdentifier<?>,org.opendaylight.yangtools.yang.binding.DataObject>

Specified by:

newWriteOnlyTransaction in interface AsyncDataTransactionFactory<org.opendaylight.yangtools.yang.binding.InstanceIdentifier<?>,org.opendaylight.yangtools.yang.binding.DataObject>

Specified by:

newWriteOnlyTransaction in interface TransactionFactory

Returns:

new write-only transaction

createTransactionChain

BindingTransactionChain createTransactionChain(TransactionChainListener listener)

Deprecated.

Description copied from interface: TransactionChainFactory

Create a new transaction chain. The chain will be initialized to read from its backing datastore, with no outstanding transaction. Listener will be registered to handle chain-level events.

Specified by:

createTransactionChain in interface TransactionChainFactory<org.opendaylight.yangtools.yang.binding.InstanceIdentifier<?>,org.opendaylight.yangtools.yang.binding.DataObject>

Parameters:

listener - Transaction chain event listener

Returns:

A new transaction chain.
