Class KiWiStore

java.lang.Object

org.openrdf.sail.helpers.SailBase

org.openrdf.sail.helpers.NotifyingSailBase

org.apache.marmotta.kiwi.sail.KiWiStore

All Implemented Interfaces:

org.openrdf.sail.NotifyingSail, org.openrdf.sail.Sail

public class KiWiStore
extends org.openrdf.sail.helpers.NotifyingSailBase

An implementation of a KiWi triple store without extended transaction support. The KiWiStore holds a reference to a KiWiPersistence object to access the database. Each SailConnection will be directly associated with a database connection and a database transaction.

Note that extended KiWi functionality like the reasoner or versioning require the extended transaction support. In these cases, please see KiWiTransactionalStore.

Method Detail

initializeInternal

protected void initializeInternal()
                           throws org.openrdf.sail.SailException

Do store-specific operations to initialize the store. The default implementation of this method does nothing.

Overrides:

initializeInternal in class org.openrdf.sail.helpers.SailBase

Throws:

org.openrdf.sail.SailException

isInitialized

public boolean isInitialized()

Overrides:

isInitialized in class org.openrdf.sail.helpers.SailBase

getDefaultContext

public String getDefaultContext()

The default context to use when no explicit context is given in createStatement. The KiWi triple store does not support null values for the context of a triple, so this URL must be set to an appropriate value

getInferredContext

public String getInferredContext()

The context to use for storing all inferred triples. The value set here will override all contexts given to addInferredTriple, because KiWi always stores all inferred triples in the same context.

getPersistence

public KiWiPersistence getPersistence()

Return a reference to the persistence object used by this KiWiStore.

Returns:

isDropTablesOnShutdown

public boolean isDropTablesOnShutdown()

Drop databases when shutdown is called. This option is mostly useful for testing.

setDropTablesOnShutdown

public void setDropTablesOnShutdown(boolean dropTablesOnShutdown)

Drop databases when shutdown is called. This option is mostly useful for testing.

getConnectionInternal

protected KiWiSailConnection getConnectionInternal()
                                            throws org.openrdf.sail.SailException

Returns a store-specific SailConnection object.

Overrides:

getConnectionInternal in class org.openrdf.sail.helpers.NotifyingSailBase

Returns:

A connection to the store.

Throws:

org.openrdf.sail.SailException

shutDownInternal

protected void shutDownInternal()
                         throws org.openrdf.sail.SailException

Do store-specific operations to ensure proper shutdown of the store.

Specified by:

shutDownInternal in class org.openrdf.sail.helpers.SailBase

Throws:

org.openrdf.sail.SailException

closeValueFactory

public void closeValueFactory()

In case there is a value factory managed by this repository directly, close it (and the underlying database connection)

isWritable

public boolean isWritable()
                   throws org.openrdf.sail.SailException

Checks whether this Sail object is writable, i.e. if the data contained in this Sail object can be changed.

Throws:

org.openrdf.sail.SailException

getValueFactory

public org.openrdf.model.ValueFactory getValueFactory()

Gets a ValueFactory object that can be used to create URI-, blank node-, literal- and statement objects.

Returns:

a ValueFactory object for this Sail object.

garbageCollect

public void garbageCollect()
                    throws org.openrdf.sail.SailException

Manually call the garbage collector for the triple store. Otherwise it will run every hour.

Throws:

org.openrdf.sail.SailException

checkConsistency

public boolean checkConsistency()
                         throws org.openrdf.sail.SailException

Throws:

org.openrdf.sail.SailException
