Method Details

getDefaultIsolationLevel

public IsolationLevel getDefaultIsolationLevel()

Description copied from interface: Sail

Retrieves the default IsolationLevel level on which transactions in this Sail operate.

Specified by:

getDefaultIsolationLevel in interface Sail

Overrides:

getDefaultIsolationLevel in class SailWrapper

Returns:

the IsolationLevel that will be used with SailConnection.begin(), for SAIL connections returned by Sail.getConnection().

getSupportedIsolationLevels

public List<IsolationLevel> getSupportedIsolationLevels()

Description copied from interface: Sail

Retrieve the IsolationLevels supported by this SAIL, ordered by increasing complexity.

Specified by:

getSupportedIsolationLevels in interface Sail

Overrides:

getSupportedIsolationLevels in class SailWrapper

Returns:

a non-empty List of supported Isolation Levels, in order of increasing complexity. Every SAIL supports at least one IsolationLevel.
