ObjectViewRegisteringFactoryHelper
public class ViewRegisteringFactoryHelper
Utility class to help DataStoreFactories for org.geotools.data.sql.SqlDataStores
register the views provided in a java.util.Map
in the call to the factory's
createDataStore(Map)
method.
NOTE this class is a rough copy of the one in the sql-datastore unsupported module. We are incorporating it here as don't want to depend on sql-datastore. Thus, it's expected to be replaced by the original once we work out what to do with the sql-datastore module.
Due to the non hierarchical nature of a Map, it is no so easy to provide a variable number of arguments on it for the same keyword, since they're usually read from a .properties file.
This class helps to minimize the work needed to provide such a mapping of various SQL views to an in-process feature type by defining the following structure for a Map<String,String> passed to createDataStore. Example .properties file:
<code> dbtype=... <usual datastore's parameters>... sqlView.1.typeName = ViewType1 sqlView.1.sqlQuery = select gid, the_geom, table2.someField \ from table1, table2 \ where table1.gid = table2.table1_id sqlView.2.typeName = ViewType2 sqlView.2.sqlQuery = select ... </code>This way, this class' utility method #registerSqlViews(SqlDataStore, Map) will receive a org.geotools.data.sql.SqlDataStore and the Map of datastore factory parameters and call org.geotools.data.sql.SqlDataStore#registerView(String, String) for each pair of
sqlView.N.typeName, sqlView.N.sqlQuery
