Data::FormValidator::CUserrContributData::FormValidator::ConstraintsFactory(3)

NAME
       Data::FormValidator::ConstraintsFactory - Module to create constraints
       for HTML::FormValidator.

DESCRIPTION
       This module contains functions to help generate complex constraints.

       If you are writing new code, take a look at
       Data::FormValidator::Constraints::MethodsFactory instead. It's a modern
       alternative to what's here, offering improved names and syntax.

SYNOPSIS
	   use Data::FormValidator::ConstraintsFactory qw( :set :bool );

	   constraints => {
	   param1 => make_or_constraint(
		   make_num_set_constraint( -1, ( 1 .. 10 ) ),
		   make_set_constraint( 1, ( 20 .. 30 ) ),
		 ),
	   province => make_word_set_constraint( 1, "AB QC ON TN NU" ),
	   bid	=> make_range_constraint( 1, 1, 10 ),
	   }

BOOLEAN CONSTRAINTS
       Those constraints are available by using the ":bool" tag.

   make_not_constraint( $c1 )
       This will create a constraint that will return the negation of the
       result of constraint $c1.

   make_or_constraint( @constraints )
       This will create a constraint that will return the result of the first
       constraint that return an non false result.

   make_and_constraint( @constraints )
       This will create a constraint that will return the result of the first
       constraint that return an non false result only if all constraints
       returns a non-false results.

SET CONSTRAINTS
       Those constraints are available by using the ":set" tag.

   make_set_constraint( $res, @elements )
       This will create a constraint that will return $res if the value is one
       of the @elements set, or the negation of $res otherwise.

       The "eq" operator is used for comparison.

   make_num_set_constraint( $res, @elements )
       This will create a constraint that will return $res if the value is one
       of the @elements set, or the negation of $res otherwise.

       The "==" operator is used for comparison.

   make_word_set_constraint( $res, $set )
       This will create a constraint that will return $res if the value is a
       word in $set, or the negation of $res otherwise.

   make_cmp_set_constraint( $res, $cmp, @elements )
       This will create a constraint that will return $res if the value is one
       of the @elements set, or the negation of $res otherwise.

       $cmp is a function which takes two argument and should return true or
       false depending if the two elements are equal.

NUMERICAL LOGICAL CONSTRAINTS
       Those constraints are available by using the ":num" tag.

   make_clamp_constraint( $res, $low, $high )
       This will create a constraint that will return $res if the value is
       between $low and $high bounds included or its negation otherwise.

   make_lt_constraint( $res, $bound )
       This will create a constraint that will return $res if the value is
       lower than $bound, or the negation of $res otherwise.

   make_le_constraint( $res, $bound )
       This will create a constraint that will return $res if the value is
       lower or equal than $bound, or the negation of $res otherwise.

   make_gt_constraint( $res, $bound )
       This will create a constraint that will return $res if the value is
       greater than $bound, or the negation of $res otherwise.

   make_ge_constraint( $res, $bound )
       This will create a constraint that will return $res if the value is
       greater or equal than $bound, or the negation of $res otherwise.

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