@DeclareRoles(value={"org.imixs.ACCESSLEVEL.NOACCESS","org.imixs.ACCESSLEVEL.READERACCESS","org.imixs.ACCESSLEVEL.AUTHORACCESS","org.imixs.ACCESSLEVEL.EDITORACCESS","org.imixs.ACCESSLEVEL.MANAGERACCESS"})

public class ModelService
extends Object
implements org.imixs.workflow.ExtendedModel

The ModelManager is independend form the IX JEE Entity EJBs and uses the standard IntemCollection Object as a data transfer object to comunitcate with clients. Since Version 1.7.0 The Implementation handles multiple model versions. Different Versions of an Model Entity can be saved and updated. The Getter methods can be furthermore Controlled by providing a valid Model Version. If no model version is set this Implementation automatically defaults to the highest available ModelVersion
