class Position from TDataXtd inherits Attribute from TDF
---Purpose: Position of a Label
uses
RelocationTable from TDF,
GUID from Standard,
Attribute from TDF,
Pnt from gp,
Label from TDF
is
Set(myclass; aLabel: Label from TDF; aPos : Pnt from gp);
---Purpose: Create if not found the TDataXtd_Position attribute set its position to <aPos>
Set (myclass; aLabel : Label from TDF)
---Purpose: Find an existing, or create an empty, Position.
-- the Position attribute is returned.
returns Position from TDataXtd;
Get(myclass; aLabel: Label from TDF; aPos : in out Pnt from gp)
---Purpose: Search label <aLabel) for the TDataXtd_Position attribute and get its position
-- if found returns True
returns Boolean from Standard;
Create
returns mutable Position from TDataXtd;
ID(me) returns GUID from Standard
is redefined static;
---Purpose: Returns the ID of the attribute.
---C++: return const &
GetID(myclass) returns GUID from Standard;
---Purpose: Returns the ID of the attribute.
---C++: return const &
Restore(me: mutable; anAttribute : Attribute from TDF)
is redefined;
---Purpose: Restores the contents from <anAttribute> into this
-- one. It is used when aborting a transaction.
--
-- Copy use methods
-- ----------------
NewEmpty(me)
returns mutable Attribute from TDF
is redefined;
---Purpose: Returns an new empty attribute from the good end
-- type. It is used by the copy algorithm.
Paste(me; intoAttribute : mutable Attribute from TDF;
aRelocTationable : mutable RelocationTable from TDF)
is redefined;
---Purpose: This method is different from the "Copy" one,
-- because it is used when copying an attribute from
-- a source structure into a target structure. This
-- method pastes the current attribute to the label
-- corresponding to the insertor. The pasted
-- attribute may be a brand new one or a new version
-- of the previous one.
GetPosition (me)
---C++: return const &
returns Pnt from gp;
SetPosition (me: mutable ; aPos : Pnt from gp);
fields
myPosition : Pnt from gp;
