public DatabaseMetaData getMetaData() throws SQLException
SQLException
public Connection getCon()
public String getGenericClassName()
CayenneDataObject
. If
generic class name is null (which is the default), DbLoader will assign each entity
a unique class name derived from the table name.
public void setGenericClassName(String genericClassName)
CayenneDataObject
. If
generic class name is set to null (which is the default), DbLoader will assign each
entity a unique class name derived from the table name.

public List getTables(String catalog, String schemaPattern, String tableNamePattern, String[] types) throws SQLException
catalog
- The name of the catalog, may be null.schemaPattern
- The pattern for schema name, use "%" for wildcard.tableNamePattern
- The pattern for table names, % for wildcard, if null or ""
defaults to "%".types
- The types of table names to retrieve, null returns all types.
SQLException
public boolean loadDbEntities(DataMap map, List tables) throws SQLException
map
- DataMap to be populated with DbEntities.tables
- The list of org.objectstyle.ashwood.dbutil.Table objects for which
DbEntities must be created.

SQLException
public void loadProceduresFromDB(String schemaPattern, String namePattern, DataMap dataMap) throws SQLException
As of 1.1 there is no boolean property or delegate method to make procedure loading optional or to implement custom merging logic, so currently this method is NOT CALLED from "loadDataMapFromDB" and should be invoked explicitly by the user.
