23 | class SelectSuite from IFSelect inherits SelectDeduct from IFSelect |
24 | |
25 | ---Purpose : A SelectSuite can describe a suite of SelectDeduct as a unique |
26 | -- one : in other words, it can be seen as a "macro selection" |
27 | -- |
28 | -- It works by applying each of its items (which is a |
29 | -- SelectDeduct) on the result computed by the previous one |
30 | -- (by using Alternate Input) |
31 | -- |
32 | -- But each of these Selections used as items may be used |
33 | -- independently, it will then give its own result |
34 | -- |
35 | -- Hence, SelectSuite gives a way of defining a new Selection |
36 | -- from existing ones, without having to do copies or saves |
37 | |
38 | uses CString, AsciiString from TCollection, |
39 | SequenceOfTransient from TColStd, |
40 | Graph from Interface, EntityIterator from Interface, |
41 | Selection from IFSelect |
42 | |
43 | raises InterfaceError |
44 | |
45 | is |
46 | |
47 | Create returns SelectSuite; |
48 | ---Purpose : Creates an empty SelectSuite |
49 | |
50 | AddInput (me : mutable; item : Selection) returns Boolean; |
51 | ---Purpose : Adds an input selection. I.E. : |
52 | -- If <item> is a SelectDeduct, adds it as Previous, not as Input |
53 | -- Else, sets it as Input |
54 | -- Returns True when done |
55 | -- Returns False and refuses to work if Input is already defined |
56 | |
57 | AddPrevious (me : mutable; item : SelectDeduct); |
58 | ---Purpose : Adds a new first item (prepends to the list). The Input is not |
59 | -- touched |
60 | -- If <item> is null, does nothing |
61 | |
62 | AddNext (me : mutable; item : SelectDeduct); |
63 | ---Purpose : Adds a new last item (prepends to the list) |
64 | -- If <item> is null, does nothing |
65 | |
66 | NbItems (me) returns Integer; |
67 | ---Purpose : Returns the count of Items |
68 | |
69 | Item (me; num : Integer) returns SelectDeduct; |
70 | ---Purpose : Returns an item from its rank in the list |
71 | -- (the Input is always apart) |
72 | |
73 | SetLabel (me : mutable; lab : CString); |
74 | ---Purpose : Sets a value for the Label |
75 | |
76 | -- Definitions for Selecting |
77 | |
78 | RootResult (me; G : Graph) returns EntityIterator |
79 | raises InterfaceError; |
80 | ---Purpose : Returns the list of selected entities |
81 | -- To do this, once InputResult has been taken (if Input or |
82 | -- Alternate has been defined, else the first Item gives it) : |
83 | -- this result is set as alternate input for the first item, |
84 | -- which computes its result : this result is set as alternate |
85 | -- input for the second item, etc... |
86 | |
87 | Label (me) returns AsciiString from TCollection; |
88 | ---Purpose : Returns the Label |
89 | -- Either it has been defined by SetLabel, or it will give |
90 | -- "Suite of nn Selections" |
91 | |
92 | fields |
