---Copyright: MATRA DATAVISION 1997
---Version: 0.0
---History: Version Date Purpose
-- 0.0 Feb 5 1997 Creation
package TDF
---Purpose: This package provides data framework for binding
-- features and data structures.
--
-- The feature structure is a tree used to bind
-- semantic informations about each feature together.
--
-- The only one concrete attribute defined in this
-- package is the TagSource attribute.This attribute
-- is used for random creation of child labels under
-- a given label. Tags are randomly delivered.
---Category: GUID - AttributeID

---Purpose: A label is a feature in the structure.
imported HAllocator;
imported LabelNode;
pointer LabelNodePtr to LabelNode from TDF;
deferred class Attribute;
---Purpose: A class each application has to implement. It is
-- used to contain the application data.
class TagSource;
---Purpose: this attribute may be used for automatic delivery of
-- labels under a given label.
class Reference;
---Purpose: this attribute is used to store in the framework a
-- reference to an other label.
---Category: DF Copy algorithms
-- ==============================================================
class ClosureMode;
---Purpose: This class provides options closure management.
class ClosureTool;
---Purpose: This class gives services around the transitive
-- enclosure of a set of information, starting from a
-- list of label.
class CopyTool;
---Purpose: This class gives services around copy/paste actions.
class CopyLabel;
---Purpose: This class gives copy of source label hierarchy
class ComparisonTool;
---Purpose: This class gives services around the comparison
-- between two sets of information.
---Category: DF Transaction & Delta
-- ==============================================================
class Transaction;
---Purpose: This class offers services to open, commit or
-- abort a transaction in a more secure way than
-- using Data from TDF.
class Delta;
---Purpose: A set of AttributeDelta for a given transaction
-- number and reference time number.
deferred class AttributeDelta;
---Purpose: Delta for a given attribute.
class DeltaOnAddition;
---Purpose: Attribute delta on ADDITION action.
class DeltaOnForget;
---Purpose: Attribute delta on FORGET action.
class DeltaOnResume;
---Purpose: Attribute delta on RESUME action.
deferred class DeltaOnRemoval;
---Purpose: Attribute delta on REMOVAL action.
deferred class DeltaOnModification;
---Purpose: Attribute delta on MODIFICATION action.
class DefaultDeltaOnRemoval;
---Purpose: Default implementation of TDF_DeltaOnRemoval.
class DefaultDeltaOnModification;
---Purpose: Default implementation of TDF_DeltaOnModification.
---Category: DF Basic Tools
-- ==============================================================
class ChildIterator;
---Purpose: A tool to iterate on the children of a label.
class ChildIDIterator;
---Purpose: A tool to iterate on the children of a label to
-- find attributes with an ID.
imported AttributeIterator;
---Purpose: DO NOT USE THIS CLASS WITHOUT AUTHORIZATION!
---Category: DF Specific Tools
-- ==============================================================
class DataSet;
---Purpose: This class is used to build a set of DF
-- informations like labels or attributes.
class RelocationTable;
---Purpose: Builds a attribute relocation dictionnary useful
-- for copy or paste actions.
class Tool;
---Purpose: This class provides general services.
class LabelMapHasher;
---Purpose: A label hasher for label maps.
class IDFilter;
---Purpose: This class offers filtering services around an ID list.
