  com.hp.hpl.jena.db.impl.DriverRDB
      com.hp.hpl.jena.db.impl.Driver_HSQL

All Implemented Interfaces:

IRDBDriver

public class Driver_HSQL

extends DriverRDB

Author:

jand based on code by Dave Reynolds and hkuno Extends DriverRDB with HSSQLDB-specific parameters. This class requires a modified DriverRDB since it has 'package'-methods: 1. getCreateTableParams( int graphId, boolean isReif ) 2. getDbInitTablesParams() These must be set to 'protected'... or belong to that package :(

Method Detail

setConnection

public void setConnection(IDBConnection dbcon)

Set the database connection

graphIdAlloc

public int graphIdAlloc(String graphName)

Allocate an identifier for a new graph.

Specified by:

graphIdAlloc in interface IRDBDriver

Specified by:

graphIdAlloc in class DriverRDB

graphIdDealloc

public void graphIdDealloc(int graphId)

Dellocate an identifier for a graph.

Parameters:

graphId - The graph identifier.

getInsertID

public int getInsertID(String tableName)

Description copied from interface: IRDBDriver

Return an auto-generated identifier for a table row.

Parameters:

tableName - The name of the table for the insert.

Returns:

the auto-generated identifier..

getTblParams

protected void getTblParams(String[] param)

Return the parameters for table creation. 1) column type for subj, prop, obj. 2) column type for head. 3) table and index name prefix.

Parameters:

param - array to hold table creation parameters.

getDbInitTablesParams

protected String[] getDbInitTablesParams()

Return the parameters for database initialization.

Specified by:

getDbInitTablesParams in class DriverRDB

getCreateTableParams

protected String[] getCreateTableParams(int graphId,
                                        boolean isReif)

Return the parameters for table creation. Generate the table name by counting the number of existing tables for the graph. This is not reliable if another client is concurrently trying to create a table so, if failure, we make several attempts to create the table.

Specified by:

getCreateTableParams in class DriverRDB
