1 # A module containing constraints that have set.elements as left hand |
2 # side. |
3 module Gecode::SetElements #:nodoc: |
4 # A SetElementsOperand is an uncommon operand that results from calling |
5 # SetOperand#elements. It facilitates placing the constraints defined |
6 # in SetElementsConstraintReceiver |
7 # |
8 # ==== Examples |
9 # |
10 # Producing a SetElementsOperand from +set_operand+: |
11 # |
12 # set_operand.elements |
13 # |
14 class SetElementsOperand |
15 include Gecode::Operand |
16 |
17 # Constructs a new set elements operand +set+. |
18 def initialize(set) #:nodoc: |
19 unless set.respond_to? :to_set_var |
20 raise TypeError, "Expected set operand, got #{set.class}." |
21 end |
22 |
23 @set = set |
24 end |
25 |
26 # Returns the set operand that makes up the set elements operand. |

40 end |
41 |
42 # SetElementsConstraintReceiver contains all constraints that can be |
43 # placed on a SetElementsOperand. |
44 # |
45 # Constraints are placed by calling SetElementsOperand#must (or any other |
46 # of the variations defined in Operand), which produces a |
47 # SetElementsConstraintReceiver from which the desired constraint can |
48 # be used. |
49 # |
50 # Each constraint accepts a number of options. See ConstraintReceiver |
51 # for more information. |
52 # |
53 # ==== Examples |
54 # |
55 # Constrains all elements in +set_operand+ to be strictly greater than 17 |
56 # using SetOperand#elements and SetElementsConstraintReceiver#>: |
57 # |
58 # set.elements.must > 17 |
59 # |
60 # Constrains all elements in +set_operand+ to be strictly greater than |
61 # +int_operand+ using SetOperand#elements and SetElementsConstraintReceiver#>: |
62 # |
63 # set.elements.must > int_operand |
64 # |
65 # The same as above, but specifying that strength :domain should be |
66 # used and that the constraint should be reified with +bool_operand+: |
67 # |
68 # set.elements.must_be.greater_than(int_operand, :strength => :domain, :reify => bool_operand) |
69 # |
70 class SetElementsConstraintReceiver < Gecode::ConstraintReceiver |
71 # Raises TypeError unless the left hand side is set elements operand. |
72 def initialize(model, params) #:nodoc: |
73 super |
74 |
75 unless params[:lhs].respond_to? :to_set_elements |
76 raise TypeError, 'Must have set elements operand as left hand side.' |
77 end |
78 end |
79 end |
80 end |
81 |
82 module Gecode::Set #:nodoc: |
83 module SetOperand |
84 # Produces a SetElementsOperand on which relation constraints can be placed that |
85 # constrain all elements in the set. |
86 # |
87 # ==== Examples |
88 # |

90 # set.elements |
