23 | class SignCounter from IFSelect inherits SignatureList |
24 | |
25 | ---Purpose : SignCounter gives the frame to count signatures associated |
26 | -- with entities, deducted from them. Ex.: their Dynamic Type. |
27 | -- |
28 | -- It can sort a set of Entities according a signature, i.e. : |
29 | -- - list of different values found for this Signature |
30 | -- - for each one, count and list of entities |
31 | -- Results are returned as a SignatureList, which can be queried |
32 | -- on the count (list of strings, count per signature, or list of |
33 | -- entities per signature) |
34 | -- |
35 | -- A SignCounter can be filled, either directly from lists, or |
36 | -- from the result of a Selection : hence, its content can be |
37 | -- automatically recomputed as desired |
38 | -- |
39 | -- SignCounter works by using a Signature in its method AddSign |
40 | -- |
41 | -- Methods can be redefined to, either |
42 | -- - directly compute the value without a Signature |
43 | -- - compute the value in the context of a Graph |
44 | |
45 | uses CString, Transient, MapOfTransient, HAsciiString from TCollection, |
46 | HSequenceOfTransient, |
47 | InterfaceModel, Graph, Selection, Signature |
48 | |
49 | is |
50 | |
51 | Create (withmap : Boolean = Standard_True; |
52 | withlist : Boolean = Standard_False) returns mutable SignCounter; |
53 | ---Purpose : Creates a SignCounter, without proper Signature |
54 | -- If <withmap> is True (default), added entities are counted |
55 | -- only if they are not yet recorded in the map |
56 | -- Map control can be set off if the input garantees uniqueness |
57 | -- of data |
58 | -- <withlist> is transmitted to SignatureList (option to list |
59 | -- entities, not only to count them). |
60 | |
61 | Create (matcher : mutable Signature; |
62 | withmap : Boolean = Standard_True; |
63 | withlist : Boolean = Standard_False) returns mutable SignCounter; |
64 | ---Purpose : Creates a SignCounter, with a predefined Signature |
65 | -- Other arguments as for Create without Signature. |
66 | |
67 | Signature (me) returns mutable Signature; |
68 | ---Purpose : Returns the Signature used to count entities. It can be null. |
69 | |
70 | SetMap (me : mutable; withmap : Boolean); |
71 | ---Purpose : Changes the control status. The map is not cleared, simply |
72 | -- its use changes |
73 | |
74 | AddEntity (me : mutable; ent : Transient; model : InterfaceModel) |
75 | returns Boolean is virtual; |
76 | ---Purpose : Adds an entity by considering its signature, which is given by |
77 | -- call to method AddSign |
78 | -- Returns True if added, False if already in the map (and |
79 | -- map control status set) |
80 | |
81 | AddSign (me : mutable; ent : Transient; model : InterfaceModel) |
82 | is virtual; |
83 | ---Purpose : Adds an entity (already filtered by Map) with its signature. |
84 | -- This signature can be computed with the containing model. |
85 | -- Its value is provided by the object Signature given at start, |
86 | -- if no Signature is defined, it does nothing. |
87 | -- |
88 | -- Can be redefined (in this case, see also Sign) |
89 | |
90 | AddList (me : mutable; list : HSequenceOfTransient; model : InterfaceModel); |
91 | ---Purpose : Adds a list of entities by adding each of the items |
92 | |
93 | AddWithGraph (me : mutable; list : HSequenceOfTransient; graph : Graph) |
94 | is virtual; |
95 | ---Purpose : Adds a list of entities in the context given by the graph |
96 | -- Default just call basic AddList |
97 | -- Can be redefined to get a signature computed with the graph |
98 | |
99 | AddModel (me : mutable; model : InterfaceModel); |
100 | ---Purpose : Adds all the entities contained in a Model |
101 | |
102 | AddFromSelection (me : mutable; sel : Selection; G : Graph); |
103 | ---Purpose : Adds the result determined by a Selection from a Graph |
104 | -- Remark : does not impact at all data from SetSelection & Co |
105 | |
106 | -- Counting on selection result -- |
107 | |
108 | SetSelection (me : mutable; sel : Selection); |
109 | ---Purpose : Sets a Selection as input : this causes content to be cleared |
110 | -- then the Selection to be ready to compute (but not immediatly) |
111 | |
112 | Selection (me) returns Selection; |
113 | ---Purpose : Returns the selection, or a null Handle |
114 | |
115 | SetSelMode (me : mutable; selmode : Integer); |
116 | ---Purpose : Changes the mode of working with the selection : |
117 | -- -1 just clears optimisation data and nothing else |
118 | -- 0 clears it 1 inhibits it for computing (but no clearing) |
119 | -- 2 sets it active for computing |
120 | -- Default at creation is 0, after SetSelection (not null) is 2 |
121 | |
122 | SelMode (me) returns Integer; |
123 | ---Purpose : Returns the mode of working with the selection |
124 | |
125 | ComputeSelected (me : mutable; G : Graph; forced : Boolean=Standard_False) |
126 | returns Boolean; |
127 | ---Purpose : Computes from the selection result, if selection is active |
128 | -- (mode 2). If selection is not defined (mode 0) or is inhibited |
129 | -- (mode 1) does nothing. |
130 | -- Returns True if computation is done (or optimised), False else |
131 | -- This method is called by ComputeCounter from WorkSession |
132 | -- |
133 | -- If <forced> is True, recomputes systematically |
134 | -- Else (D), if the counter was not cleared and if the former |
135 | -- computed result started from the same total size of Graph and |
136 | -- same count of selected entities : computation is not redone |
137 | -- unless <forced> is given as True |
138 | |
139 | |
140 | Sign (me; ent : Transient; model : InterfaceModel) |
141 | returns HAsciiString is virtual; |
142 | ---Purpose : Determines and returns the value of the signature for an |
143 | -- entity as an HAsciiString. This method works exactly as |
144 | -- AddSign, which is optimized |
145 | -- |
146 | -- Can be redefined, accorded with AddSign |
147 | |
148 | ComputedSign (me : mutable; ent : Transient; G : Graph) returns CString; |
149 | ---Purpose : Applies AddWithGraph on one entity, and returns the Signature |
150 | -- Value which has been recorded |
151 | -- To do this, Add is called with SignOnly Mode True during the |
152 | -- call, the returned value is LastValue |
