Field Details

JENA_ISOLATION_STRATEGY

public static final String JENA_ISOLATION_STRATEGY

Represents parameter specify isolation strategy to be used.

Possible values:

• READ_COMMITTED
• SNAPSHOT

See Also:

• Constant Field Values

READ_COMMITTED

public static final String READ_COMMITTED

Default storage access isolation strategy.

Represents situation where transactions keep a list of their changes, but the read from a shared connector, meaning when a transaction commits changes, other transactions immediately see them.

See Also:

• JENA_ISOLATION_STRATEGY
• Constant Field Values

SNAPSHOT

public static final String SNAPSHOT

Storage access isolation strategy.

Represents situations where each transaction acquires a complete snapshot of the repository and works with it.

See Also:

• JENA_ISOLATION_STRATEGY
• Constant Field Values

JENA_STORAGE_TYPE

public static final String JENA_STORAGE_TYPE

Represents parameter specifying type of storage to be used by this driver.

Possible values are:

• FILE
• IN_MEMORY
• TDB

See Also:

• Constant Field Values

FILE

public static final String FILE

Plain file storage.

See Also:

• JENA_STORAGE_TYPE
• Constant Field Values

IN_MEMORY

public static final String IN_MEMORY

In-memory storage.

See Also:

• JENA_STORAGE_TYPE
• Constant Field Values

TDB

public static final String TDB

Jena TDB storage.

See Also:

• JENA_STORAGE_TYPE
• Constant Field Values

TDB2

public static final String TDB2

Jena TDB2 storage.

See Also:

• JENA_STORAGE_TYPE
• Constant Field Values

FUSEKI

public static final String FUSEKI

Jena Fuseki server.

See Also:

• JENA_STORAGE_TYPE
• Constant Field Values

JENA_TREAT_DEFAULT_GRAPH_AS_UNION

public static final String JENA_TREAT_DEFAULT_GRAPH_AS_UNION

Parameter specifying whether the default graph should be treated as union of all the named graphs and the default graph.

Default graph being a union of all graphs is typical for storages like RDF4J, GraphDB, Virtuoso (querying without graph queries across all graphs).

This parameter influences only querying/reading. It has no effect on write operations, which work with the default graph as is in Jena.
