    • Constructor Detail

      • ThreadedHsqlEpsgFactory

        public ThreadedHsqlEpsgFactory()
        Creates a new instance of this factory. If the "EPSG-HSQL.directory" system property is defined and contains the name of a directory with a valid parent, then the "EPSG" database will be saved in that directory. Otherwise, a temporary directory will be used.

      • ThreadedHsqlEpsgFactory

        public ThreadedHsqlEpsgFactory​(Hints hints)
        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.
