17 deferred class Storable from Standard
19 ---Purpose: This class Storable is an abstract class that allows built-in
20 -- primitive types to be extended. They are not themselves
21 -- persistent, but are known by the database, therefore can be used
22 -- to define the internal representation of persistent objects.
23 -- Otherwise, all the fields of subclasses of Object MUST inherit
26 -- This class provides also a framework for copying, comparing and
30 Delete ( me : out ) is virtual;
31 ---C++: alias "Standard_EXPORT virtual ~Standard_Storable(){Delete();}"
33 HashCode (me; Upper : Integer ) returns Integer is virtual;
34 ---Purpose: Returns a hashed value denoting <me>. This value is in
35 -- the range 1..<Upper>.
39 IsEqual (me; Other : Storable) returns Boolean
40 ---Purpose: Returns true if the direct contents of <me> and
41 -- <Other> are memberwise equal.
42 ---C++: alias operator ==
46 IsSimilar (me; Other : Storable) returns Boolean;
47 ---Purpose: Returns true if the Deep contents of <me> and
48 -- <Other> are memberwise equal.
