Method Details

sink

public SailSink sink(IsolationLevel level)
              throws SailException

Description copied from interface: SailSource

Create a SailSink that when when its SailSource.flush() is called, the changes are applied to this source.

Parameters:

level - If this level is compatible with IsolationLevels.SERIALIZABLE then a SailSink.prepare() can throw a SailConflictException.

Returns:

Newly created SailSink

Throws:

SailException

dataset

public MemorySailStore.MemorySailDataset dataset(IsolationLevel level)
                                          throws SailException

Description copied from interface: SailSource

Create an observable SailDataset of the current state of this SailSource. Repeatedly calling with methods with IsolationLevels.SNAPSHOT (or higher) isolation levels will result in SailDatasets that are all derived from the same state of the backing SailSource (if applicable), that is the only difference between the states of the SailDataset will be from changes using this SailSource.sink(IsolationLevel).

Parameters:

level - If this is compatible with IsolationLevels.SNAPSHOT_READ the resulting SailDataset will observe a single state of this SailSource.

Returns:

an SailDataset of the current state

Throws:

SailException
