Constructor Details

HsqlDialectEpsgMediator

public HsqlDialectEpsgMediator()
                        throws FactoryException

Creates a new instance of this factory.

Throws:

FactoryException

HsqlDialectEpsgMediator

public HsqlDialectEpsgMediator(Hints hints)
                        throws FactoryException

Creates a new instance of this data source using the specified hints. The priority is set to a lower value than the FactoryOnAccess's one in order to give precedence to the Access-backed database, if presents. Priorities are set that way because:

• The MS-Access format is the primary EPSG database format.
• If a user downloads the MS-Access database himself, he probably wants to use it.

Throws:

FactoryException

HsqlDialectEpsgMediator

public HsqlDialectEpsgMediator(int priority,
 DataSource datasource)

Creates an HsqlDialectEpsgMediator with a 20 min timeout, single worker, and no cache.

public HsqlDialectEpsgMediator(int priority,
 Hints hints,
 DataSource datasource)
