Public Member Functions

 InsertionNode (Document *pownerDoc)
 ~InsertionNode ()
 This destructor was added by Simon 28/10/95 to solve a problem with Insertion Nodes being destroyed. If a layer is deleted which contains an Insertion Node (This can occur when throwing away undo info) then we must inform the document containing the InsertionNode, so that it can NULLIFY it's pointer to it.
virtual UINT32 GetNodeSize () const
 For finding the size of the node.
virtual BOOL IsAnInsertionNode () const

Protected Member Functions

virtual Node * SimpleCopy ()
 This method returns a shallow copy of the node with all Node pointers NULL. The function is virtual, and must be defined for all derived classes.

Protected Attributes

Document * pOwnerDoc

Detailed Description

Created: 04/07/94 Author: Simon_Maneggio (Xara Group Ltd) <camelotdev@xara.com> Purpose: The insertion node is used to locate the position in the tree where new objects are inserted. A pointer to the insertion node is stored in the Document object.

There will be only one instance of an InsertionNode in each camelot document. It will live as a last child of the the selected spread's active layer.
