Package oracle.ide.model Description

Contains interfaces and classes implementing JDeveloper's data model. In JDeveloper persistent data, such as projects and java files, are encapsulated by objects implementing the Node or oracle.ide.model.Container interface. Other objects, such as the structure of an xml file, are encapsulated by implementations of the Element or Folder interface. Generally, these structural elements are transient objects that are constantly re-created as the content of the xml file is updated by the user.

Data model classes are oracle.ide.addin.Subjects that can be observed by objects that implement the oracle.ide.addin.Observer interface. In general, changes to the data model should be undoable and delegated from a oracle.ide.addin.View to that view's oracle.ide.addin.Controller. It is the responsability of the Controller to use the oracle.ide.CommandProcessor to execute a oracle.ide.addin.Command implementation that changes the data model, notifies model observers of the change, and has the ability to undo the changes done to the model.

Note from the description above it is the responsability of the object that modifies data to send oracle.ide.addin.UpdateMessage notifications when the data model is changed. This allows batching up data model changes avoiding thus the proliferation of change notification messages. In the framework, the data model is only responsible for maintaining data.
