Class DocumentNode

Remark

Each class that inherits from Spotfire.Dxp.Framework.DocumentModel.DocumentNode must follow the design pattern for document nodes. This includes: The class must be marked with the System.SerializableAttribute attribute.If objects of the class are intended to be persisted when the Spotfire document is saved, the class must be marked with the Spotfire.Dxp.Framework.Persistence.PersistenceVersionAttribute attribute.The class must not implement any of the System.IDisposable or System.Runtime.Serialization.IDeserializationCallback interfaces.The class must not declare any events.All fields declared in the class must be marked readonly.The type of each field declared in the class must be one of the following: A primitive type (string, bool, float, etc.). An immutable type. A type that derives from Spotfire.Dxp.Framework.DocumentModel.DocumentNode. One of the Undoable building blocks of the document model (Spotfire.Dxp.Framework.DocumentModel.UndoableProperty, Spotfire.Dxp.Framework.DocumentModel.UndoableList, Spotfire.Dxp.Framework.DocumentModel.UndoableDictionary, etc.). An instance of the Spotfire.Dxp.Framework.DocumentModel.RuntimeProperty type. An instance of the Spotfire.Dxp.Framework.DocumentModel.RuntimeConstant type. The class must declare a nested class called PropertyNames that derives from the PropertyNames class declared by the inherited document node class. The PropertyNames class declared in this class shall shadow the inherited PropertyNames class, which is accomplished using the new keyword.The class must declare a protected (or private if this class is sealed) deserialization constructor in which or are called to deserialize persisted state and initialize the fields of this class.The class must override Spotfire.Dxp.Framework.DocumentModel.DocumentNode.GetObjectData|GetObjectData(info, context) in which or are called to serialize the state held by the fields of this class.
