Class ORMappingSchemeImp

java.lang.Object
  tudresden.ocl.sql.ORMappingSchemeImp

All Implemented Interfaces:

ORMappingScheme

public class ORMappingSchemeImp

extends Object

implements ORMappingScheme

An implementation of the ORMappingScheme interface. It uses an implementation of the ORMapping interface to query object relational mapping information and provides these information to the SQLCodegenerator with help of the appropriate structures.

Constructor Detail

ORMappingSchemeImp

public ORMappingSchemeImp(ORMapping orm)
                   throws IllegalArgumentException

Call this constructor to create an instance of ORMappingSchemeImp.

Parameters:

orm - an implementation of the ORMapping interface

Throws:

IllegalArgumentException - if orm is null

Method Detail

getMappedClass

public MappedClass getMappedClass(String name)

Specified by:

getMappedClass in interface ORMappingScheme

Parameters:

name - the name of an application type

Returns:

a MappedObject containing all necessary information to generate SQL code

createMappedClasses

private void createMappedClasses()

Creates a MappedClass object for each classifier and fills it with the according tables that already contain the attribute information. As far as associations are mapped to foreign key references with the help of attributes, they are already contained within that tables too.

createMappedClassLinks

private void createMappedClassLinks()

Creates all necessary links between MappedClass objects. These links result from association ends and generalization relationships. Futhermore, the according guides will be inserted.

insertQueryMethodes

private void insertQueryMethodes()

Inserts information about query methodes contained by the classes in the class model.
