Method Detail

snapshotCreated

public abstract void snapshotCreated(Snapshot newSnapshot)

Implement this method to receive notification when a snapshot is requested via Transaction.setSnapshotOnNextOperation().

Parameters:

newSnapshot - the snapshot that has been created.

initializeNative

protected long initializeNative(long... nativeParameterHandles)

Description copied from class: RocksCallbackObject

Construct the Native C++ object which will callback to our object methods

Specified by:

initializeNative in class RocksCallbackObject

Parameters:

nativeParameterHandles - An array of native handles for any parameter objects that are needed during construction

Returns:

The native handle of the C++ object which will callback to us

disposeInternal

protected void disposeInternal()

Deletes underlying C++ TransactionNotifier pointer. Note that this function should be called only after all Transactions referencing the comparator are closed. Otherwise an undefined behavior will occur.

Overrides:

disposeInternal in class RocksCallbackObject

disposeInternal

protected final void disposeInternal(long handle)
