Method Detail

writeToTransaction

<T extends org.opendaylight.yangtools.yang.binding.DataObject> void writeToTransaction(org.opendaylight.controller.md.sal.common.api.data.LogicalDatastoreType store,
                                                                                       org.opendaylight.yangtools.yang.binding.InstanceIdentifier<T> path,
                                                                                       T data)

Method creates put operation using provided data in underlying transaction chain.

writeToTransactionWithParentsSlow

<T extends org.opendaylight.yangtools.yang.binding.DataObject> void writeToTransactionWithParentsSlow(org.opendaylight.controller.md.sal.common.api.data.LogicalDatastoreType store,
                                                                                                      org.opendaylight.yangtools.yang.binding.InstanceIdentifier<T> path,
                                                                                                      T data)

Method creates put operation using provided data in underlying transaction chain and flag to create missing parents. WARNING: This method is slow because of additional reading cost. Use it only if you really need to create parents.

addDeleteToTxChain

<T extends org.opendaylight.yangtools.yang.binding.DataObject> void addDeleteToTxChain(org.opendaylight.controller.md.sal.common.api.data.LogicalDatastoreType store,
                                                                                       org.opendaylight.yangtools.yang.binding.InstanceIdentifier<T> path)

Method creates delete operation for provided path in underlying transaction chain.

submitTransaction

boolean submitTransaction()

Method submits Transaction to DataStore.

Returns:

transaction is submitted successfully

getReadTransaction

org.opendaylight.controller.md.sal.binding.api.ReadOnlyTransaction getReadTransaction()

Method exposes transaction created for device represented by this context. This read only transaction has a fresh dataStore snapshot. There is a possibility to get different data set from DataStore as write transaction in this context.

Returns:

readOnlyTransaction - Don't forget to close it after finish reading

isTransactionsEnabled

boolean isTransactionsEnabled()

Method returns true if transaction chain manager is enabled.

Returns:

is transaction chain manager enabled
