Constructor Detail

TracingBroker

public TracingBroker(String type,
                     DOMDataBroker delegate,
                     Config config,
                     BindingNormalizedNodeSerializer codec)

Method Detail

watchRegistrations

public void watchRegistrations(String iidString,
                               LogicalDatastoreType store)

Log registrations to this subtree of the md-sal.

Parameters:

iidString - the iid path of the root of the subtree

store - Which LogicalDataStore? or null for both

watchWrites

public void watchWrites(String iidString,
                        LogicalDatastoreType store)

Log writes to this subtree of the md-sal.

Parameters:

iidString - the iid path of the root of the subtree

store - Which LogicalDataStore? or null for both

newReadWriteTransaction

public DOMDataTreeReadWriteTransaction newReadWriteTransaction()

Description copied from interface: DOMTransactionFactory

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 DOMDataTreeWriteTransaction.commit() for more details about conflicting and non-conflicting changes and failure scenarios.

Specified by:

newReadWriteTransaction in interface DOMTransactionFactory

Returns:

new read-write transaction

newWriteOnlyTransaction

public DOMDataTreeWriteTransaction newWriteOnlyTransaction()

Description copied from interface: DOMTransactionFactory

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 DOMDataTreeWriteTransaction.commit() for more details about conflicting and non-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 DOMDataTreeWriteTransaction.commit().

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

Specified by:

newWriteOnlyTransaction in interface DOMTransactionFactory

Returns:

new write-only transaction

createTransactionChain

public DOMTransactionChain createTransactionChain(DOMTransactionChainListener transactionChainListener)

Description copied from interface: DOMDataBroker

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 DOMDataBroker

Parameters:

transactionChainListener - Transaction chain event listener

Returns:

A new transaction chain.

newReadOnlyTransaction

public DOMDataTreeReadTransaction newReadOnlyTransaction()

Description copied from interface: DOMTransactionFactory

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 DOMTransactionFactory

Returns:

A new read-only transaction

getExtensions

public com.google.common.collect.ClassToInstanceMap<DOMDataBrokerExtension> getExtensions()

Description copied from interface: DOMExtensibleService

Return a map of currently-supported extensions, along with accessor services which provide access to the specific functionality bound to this service.

Specified by:

getExtensions in interface DOMExtensibleService<DOMDataBroker,DOMDataBrokerExtension>

Returns:

A map of supported functionality.

printOpenTransactions

public boolean printOpenTransactions(PrintStream ps,
                                     int minOpenTXs)

Description copied from interface: TracingDOMDataBroker

Prints a human-readable "report" of all opened but not closed transactions, including transactions chains and transactions opened by them, onto the printStream.

Specified by:

printOpenTransactions in interface TracingDOMDataBroker

minOpenTXs - minimum open number of transactions (leaks with fewer are not printed)

Returns:

true if there were any open transactions, false if none
