Method Detail

getDatasetNames

String[] getDatasetNames()

list all tables

Returns:

an array of dataset names for this DataStore

getGeometryAttributes

List<GeometryColumn> getGeometryAttributes(String datasetName)

getPrimaryKeyColumns

List<PrimaryKeyColumn> getPrimaryKeyColumns(String datasetName)
                                     throws SQLException

Returns columns of this dataset involved in the Primary Key. (added on 2013-08-07)
