class ShareFlags from Interface
|
|
|
|
---Purpose : This class only says for each Entity of a Model, if it is
|
|
-- Shared or not by one or more other(s) of this Model
|
|
-- It uses the General Service "Shared".
|
|
|
|
uses HSequenceOfTransient from TColStd,
|
|

|
|
GeneralLib, Protocol from Interface, GTool, Graph

raises DomainError, OutOfRange

is
|
|
|
|
Create (amodel : InterfaceModel; lib : GeneralLib) returns ShareFlags;
|
|
---Purpose : Creates a ShareFlags from a Model and builds required data
|
|
-- (flags) by calling the General Service Library given as
|
|
-- argument <lib>
|
|
|
|
Create (amodel : InterfaceModel; gtool : GTool from Interface)
|
|
returns ShareFlags;
|
|
---Purpose : Same as above, but GeneralLib is detained by a GTool
|
|
|
|
Create (amodel : InterfaceModel; protocol : Protocol from Interface)
|
|
returns ShareFlags;
|
|
---Purpose : Same as above, but GeneralLib is defined through a Protocol
|
|
|
|
Create (amodel : InterfaceModel) returns ShareFlags;
|
|
---Purpose : Same as above, but works with the GTool of the Model
|
|
|
|
Create (agraph : Graph) returns ShareFlags;
|
|
---Purpose : Creates a ShareFlags by querying informations from a Graph
|
|
-- (remark that Graph also has a method IsShared)
|
|
|
|
Evaluate (me : in out; lib : GeneralLib; gtool : GTool) is static private;
|
|
---Purpose : Computes flags at Creation time
|
|
--
|
|
-- Normally, gtool suffices. But if a Graph is created from a
|
|
-- GeneralLib directly, it cannot be used
|
|
-- If <gtool> is defined, it has priority
|
|
|
|
Model (me) returns InterfaceModel;
|
|
---Purpose : Returns the Model used for the evaluation
|
|
|
|
IsShared (me; ent : Transient) returns Boolean
|
|
---Purpose : Returns True if <ent> is Shared by one or more other
|
|
-- Entity(ies) of the Model
|
|
raises DomainError;
|
|
-- Error if <ent> does not come from the Model
|
|
|
|
RootEntities (me) returns EntityIterator;
|
|
---Purpose : Returns the Entities which are not Shared (see their flags)
|
|
|
|
NbRoots (me) returns Integer;
|
|
---Purpose : Returns the count of root entities
|
|
|
|
Root (me; num : Integer = 1) returns any Transient
|
|
---Purpose : Returns a root entity according its rank in the list of roots
|
|
-- By default, it returns the first one
|
|
raises OutOfRange;
|
|
-- Error if <num> if not between 1 and <NbRoots>
