        Description copied from interface: DataAccess
        Access to the named resource.

        The level of access is represented by the instance of the FeatureSource being returned.

        Formally:

        • FeatureSource - read-only access
        • FeatureStore - read-write access
        • FetureLocking - concurrency control
            Additional interfaces may be supported by the implementation you are using.
        Specified by:
        getFeatureSource in interface DataAccess<FeatureType,​Feature>
        Returns:
        Access to the named resource being made available

      • dispose

        public void dispose()
        Description copied from interface: DataAccess
        Disposes of this data store and releases any resource that it is using.

        A DataStore cannot be used after dispose has been called, neither can any data access object it helped create, such as FeatureReader, FeatureSource or FeatureCollection.

        This operation can be called more than once without side effects.

        There is no thread safety assurance associated with this method. For example, client code will have to make sure this method is not called while retrieving/saving data from/to the storage, or be prepared for the consequences.

        Specified by:
        dispose in interface DataAccess<FeatureType,​Feature>
      • getSchemaParser

        protected EmfComplexFeatureReader getSchemaParser()

        the schema parser. Guaranteed non-null.
      • removeSchema

                          throws IOException
        Description copied from interface: DataAccess
        Used to permanently remove a schema from the underlying storage

        This functionality is similar to an "drop table" statement in SQL. Implementation is optional; it may not be supported by all servers or files.

        Specified by:
        removeSchema in interface DataAccess<FeatureType,​Feature>
        Throws:
