Constructor Details

TableLogger

public TableLogger(Database db, String namespace, String tableName, String partColumn, String partitionKey, ReplayerInterface replayer, DynamicTable table, boolean append, TableLogger.StoreMode storeMode, long snapshotIntervalMillis) throws IOException

Throws:

IOException

Method Details

getDefinition

public TableDefinition getDefinition()

getDefinition

public static TableDefinition getDefinition(Table table, TableLogger.StoreMode storeMode)

setReplayer

public void setReplayer(Replayer replayer)

flush

public void flush() throws IOException

Throws:

IOException

close

public void close() throws IOException

Throws:

IOException

onUpdate

public void onUpdate(Index added, Index removed, Index modified)

Description copied from interface: Listener

Process notification of table changes.

Specified by:

onUpdate in interface Listener

Specified by:

onUpdate in class InstrumentedListenerAdapter

Parameters:

added - rows added

removed - rows removed

modified - rows modified

initializeTransientFieldsForLiveness

@VisibleForTesting public final void initializeTransientFieldsForLiveness()

Package-private for Serializable sub-classes to use in readObject only. Public to allow unit tests in another package to work around mock issues where the constructor is never invoked.

tryRetainReference

public final boolean tryRetainReference()

Description copied from interface: LivenessReferent

If this referent is "live", behave as LivenessReferent.retainReference() and return true. Otherwise, returns false rather than throwing an exception.

Specified by:

tryRetainReference in interface LivenessReferent

Returns:

True if this referent was retained, false otherwise

dropReference

public final void dropReference()

Description copied from interface: LivenessReferent

Drop a previously-retained reference to this referent.

Specified by:

dropReference in interface LivenessReferent

getWeakReference

public WeakReference<? extends LivenessReferent> getWeakReference()

Description copied from interface: LivenessReferent

Get a WeakReference to this referent. This may be cached, or newly created.

Specified by:

getWeakReference in interface LivenessReferent

Returns:

A new or cached reference to this referent

tryManage

public final boolean tryManage(@NotNull LivenessReferent referent)

Description copied from interface: LivenessManager

Attempt to add the specified referent to this manager.

Specified by:

tryManage in interface LivenessManager

Parameters:

referent - The referent to add

Returns:

Whether the referent was in fact added

onReferenceCountAtZero

protected final void onReferenceCountAtZero()

Description copied from class: ReferenceCounted

Callback method that will be invoked when the reference count returns to zero.

Specified by:

onReferenceCountAtZero in class ReferenceCounted
