public class RowIdAMImpl
extends ApplicationModuleImpl

This class is the Application Module implementation for the RowId generator. The GeneratorSequenceImpl class invokes the getNextId method on this class to get the next RowId to use. Any other class can invoke the other public methods for appropriate behavior.
