NAME

6       Data::FormValidator::ConstraintsFactory - Module to create constraints
7       for HTML::FormValidator.
8

DESCRIPTION

10       This module contains functions to help generate complex constraints.
11
12       If you are writing new code, take a look at
13       Data::FormValidator::Constraints::MethodsFactory instead. It's a modern
14       alternative to what's here, offering improved names and syntax.
15

SYNOPSIS

17           use Data::FormValidator::ConstraintsFactory qw( :set :bool );
18
19           constraints => {
20           param1 => make_or_constraint(
21                   make_num_set_constraint( -1, ( 1 .. 10 ) ),
22                   make_set_constraint( 1, ( 20 .. 30 ) ),
23                 ),
24           province => make_word_set_constraint( 1, "AB QC ON TN NU" ),
25           bid  => make_range_constraint( 1, 1, 10 ),
26           }
27

BOOLEAN CONSTRAINTS

29       Those constraints are available by using the ":bool" tag.
30
31   make_not_constraint( $c1 )
32       This will create a constraint that will return the negation of the
33       result of constraint $c1.
34
35   make_or_constraint( @constraints )
36       This will create a constraint that will return the result of the first
37       constraint that return an non false result.
38
39   make_and_constraint( @constraints )
40       This will create a constraint that will return the result of the first
41       constraint that return an non false result only if all constraints
42       returns a non-false results.
43

SET CONSTRAINTS

45       Those constraints are available by using the ":set" tag.
46
47   make_set_constraint( $res, @elements )
48       This will create a constraint that will return $res if the value is one
49       of the @elements set, or the negation of $res otherwise.
50
51       The "eq" operator is used for comparison.
52
53   make_num_set_constraint( $res, @elements )
54       This will create a constraint that will return $res if the value is one
55       of the @elements set, or the negation of $res otherwise.
56
57       The "==" operator is used for comparison.
58
59   make_word_set_constraint( $res, $set )
60       This will create a constraint that will return $res if the value is a
61       word in $set, or the negation of $res otherwise.
62
63   make_cmp_set_constraint( $res, $cmp, @elements )
64       This will create a constraint that will return $res if the value is one
65       of the @elements set, or the negation of $res otherwise.
66
67       $cmp is a function which takes two argument and should return true or
68       false depending if the two elements are equal.
69

NUMERICAL LOGICAL CONSTRAINTS

71       Those constraints are available by using the ":num" tag.
72
73   make_clamp_constraint( $res, $low, $high )
74       This will create a constraint that will return $res if the value is
75       between $low and $high bounds included or its negation otherwise.
76
77   make_lt_constraint( $res, $bound )
78       This will create a constraint that will return $res if the value is
79       lower than $bound, or the negation of $res otherwise.
80
81   make_le_constraint( $res, $bound )
82       This will create a constraint that will return $res if the value is
83       lower or equal than $bound, or the negation of $res otherwise.
84
85   make_gt_constraint( $res, $bound )
86       This will create a constraint that will return $res if the value is
87       greater than $bound, or the negation of $res otherwise.
88
89   make_ge_constraint( $res, $bound )
90       This will create a constraint that will return $res if the value is
91       greater or equal than $bound, or the negation of $res otherwise.
92

OTHER CONSTRAINTS

94   make_length_constraint($max_length)
95       This will create a constraint that will return true if the value has a
96       length of less than or equal to $max_length
