Constructor Detail

AssociationDefinitionModelImpl

AssociationDefinitionModelImpl(AssociationModelImpl assoc)

Remains partially uninitialzed. Only usable as an update-model (not as a create-model).

AssociationDefinitionModelImpl

AssociationDefinitionModelImpl(AssociationModelImpl assoc,
                               String parentCardinalityUri,
                               String childCardinalityUri,
                               ViewConfigurationModelImpl viewConfig)

Parameters:

assoc - the underlying association.

postUpdate

void postUpdate(DMXObjectModel updateModel,
                DMXObjectModel oldObject)

2 assoc def specific tasks must be performed once the underlying association is updated: - Update the assoc def's cardinality (in type cache + DB). Cardinality is technically not part of the type model. So, it is not handled by the generic (model-driven) object update procedure. - Possibly rehash the assoc def in type cache. Rehashing is required if the custom assoc type has changed.

Pre condition: these 3 assoc def parts are already up-to-date through the generic (model-driven) object update procedure: - Assoc Def type (type URI). - Custom assoc type (child topics). - "Include in Label" flag (child topics).

Called when update() is called on an AssociationDefinitionModel object. This is in 2 cases: - Edit a type interactively (a type topic is selected). - Programmatically call getChildTopics().set() on an AssociationDefinitionModel object, e.g. from a migration.

Not called when an association which also acts as an assoc def is edited interactively (an association is selected). In this case: - Cardinality doesn't need to be updated as Cardinality can't be edited interactively through an association. - Rehashing is already performed in TypeModelImpl#_updateAssocDef (called from AssociationModelImpl#postUpdate)

Overrides:

postUpdate in class AssociationModelImpl

Parameters:

updateModel - the update data/instructions. Note: on post-update time updateModel and this (assoc def) model may differ at least because a) updateModel might contain only certain assoc def parts; this is called a "partial update" b) updateModel might contain refs and deletion-refs; this model never contains refs
