Naming Conventions

At this point running MapToJava with the options -factories and '-schema file-name' will create the usual java files and in the same packages as each file create a Factory. The naming convention is Abstractfile-nameFactory.java : so User.java would be accompanied by AbstractUserFactory.java.

The abstract factory contains a listing of all the java/sql field mappings, the table name, and pre-coded insert, update, and delete strings. Abstract routines from FactoryBase like (getTableName(), etc.) are implemented.^3.8 Also found are the names of the generated stored procedure name and how to call it (if the '-procs' switch was used in generation). The methods getByOid, and store are also implmented.

The next step is the declared factory. One needs to define a factory (usually class-nameFactory), to extend the abstract Factory and implement any methods you need. To UserFactory we would write any desired queries as follows.

	public User getUserById (DatabaseSession dbSess, String id) throws
SQLException {
		return (User)super.getObject (dbSess, super.userId, id);
	}

It's that simple.
