org.objectweb.speedo.metadata.SpeedoInheritance

Defines a the Speedo meta information about the inheritance. There is 3 possible mappings - The first mapping is the horizontal. Each concrete class has its own table containg all fields (fields of the class + inherited fields). The strategy for this mapping is new-table for each class. In each class, all inherited field must be mapped included inherited field. This means that in a class all inherited fields must be mapped into the tables of the current class. (#remappedInheritedFields) - The second mapping is filtered. All classes are mapped into the same tables. The table name is defined on the parent class. The strategy of the children classes is 'superclass-table'. To distinguish classes, a discriminator is required. (#discriminator) - The third mapping is vertical.All classes have its own table containing only fields of the class (not the inherited fields). Each table of devrived classes must defines a join to its parent (#join). In a vertical mapping it is possible and advised to use a discriminator similary than the filtered mapping. The strategy of the children is 'new-table'. @author S.Chassande-Barrioz
