Interface Store

public interface Store

A Store is one RDF dataset instance - it is the unit of query. The Store class is the SDB specific mechanisms need to implement an RDF Dataset. DatasetStore provide the dataset interface. A store consists of a number of handlers for different aspects of the process of setting up and querying a database-backed Store. This means Store for new databases can be assmelbed from those standard components that work, with database-specific code only where necessary. A common case if the formatting of the database - this is often DB-specific yet SQL generation of query is more standard.

Method Detail

getConnection

com.hp.hpl.jena.sdb.sql.SDBConnection getConnection()

Return the connection to the implementing database

getQueryCompilerFactory

com.hp.hpl.jena.sdb.compiler.QueryCompilerFactory getQueryCompilerFactory()

Return the producer of processors that turn SPARQL queries into SQL expressions

getSQLBridgeFactory

com.hp.hpl.jena.sdb.store.SQLBridgeFactory getSQLBridgeFactory()

Factory for SQL bridges for this store

getSQLGenerator

com.hp.hpl.jena.sdb.store.SQLGenerator getSQLGenerator()

Get the SQL-from-relational algebra generator

getTableFormatter

Return the processor that creates the database tables

getLoader

com.hp.hpl.jena.sdb.store.StoreLoader getLoader()

Return the (bulk) loader

getConfiguration

com.hp.hpl.jena.sdb.store.StoreConfig getConfiguration()

Return the configuration of this Store

close

void close()

Stores should be closed explicitly. Some stores may require specific finalization actions (e.g. embedded databases), and some stores may be able to release system resources.

isClosed

boolean isClosed()

Has this store been closed?

getSize

long getSize()

Get the size of this store

getSize

long getSize(com.hp.hpl.jena.graph.Node graphNode)

Get the size of the graph corresponding to graphNode

getTripleTableDesc

com.hp.hpl.jena.sdb.layout2.TableDescTriples getTripleTableDesc()

Where the default graph is store

getQuadTableDesc

com.hp.hpl.jena.sdb.layout2.TableDescQuads getQuadTableDesc()

Where the named graphs are in is store

getNodeTableDesc

com.hp.hpl.jena.sdb.layout2.TableDescNodes getNodeTableDesc()

Location of the nodes in the store (if meaningful)
