package TDocStd
---Purpose: This package define CAF main classes.
--
-- * The standard application root class
--
-- * The standard document wich contains data
--
-- * The external reference mechanism between documents
--
-- * Attributes for Document management
-- Standard documents offer you a ready-to-use
-- document containing a TDF-based data
-- structure. The documents themselves are
-- contained in a class inheriting from
-- TDocStd_Application which manages creation,
-- storage and retrieval of documents.
-- You can implement undo and redo in your
-- document, and refer from the data framework of
-- one document to that of another one. This is
-- done by means of external link attributes, which
-- store the path and the entry of external links. To
-- sum up, standard documents alone provide
-- access to the data framework. They also allow
-- you to:
-- - Update external links
-- - Manage the saving and opening of data
-- - Manage undo/redo functionality.
-- Note
-- For information on the relations between this
-- component of OCAF and the others, refer to the
-- OCAF User's Guide.

---Purpose: standard Application/Document
-- =============================
deferred class Application;
class Document;
class Context;
---Purpose: External reference Attribute
-- ============================
class XLink;
---Purpose: This attribute, when setted, store an external
-- reference . An external reference is a memorized link
-- between attributes wich originate from different
-- documents.
class XLinkIterator;
---Purpose: This is an iterator giving all the external references
-- of a Document.
class XLinkTool;
---Purpose: This class provide services to set, update and perform
-- external references.
---Purpose: Attributes for Document Management
-- ==================================
private class Owner;
---Purpose: This attribute located at the root label of the
-- framework contains a back reference to the owner
-- TDocStd_Document, providing acces to the document from
-- any label. private class Owner;
private class Modified;
---Purpose: This attribute located at the root label provide
-- services to register modified labels in a document.
pointer XLinkPtr to XLink from TDocStd;
private class XLinkRoot;
---Purpose: This attribute is the root of all external references
-- setted in a document.
class PathParser;
class CompoundDelta;
class LabelIDMapDataMap instantiates DataMap from TCollection (Label from TDF,
IDMap from TDF,
LabelMapHasher from TDF);
class ApplicationDelta;
class MultiTransactionManager;
class SequenceOfApplicationDelta instantiates
Sequence from TCollection(ApplicationDelta from TDocStd);
class SequenceOfDocument instantiates
Sequence from TCollection(Document from TDocStd);
---Purpose: specific GUID of this package
-- =============================
IDList (anIDList : in out IDList from TDF);
---Purpose: Appends to <anIDList> the list of the attributes
-- IDs of this package. CAUTION: <anIDList> is NOT
-- cleared before use.
