SYNOPSIS

13           use MooseX::Types:::Moose qw/Str Any/;
14           use Moose::Util::TypeConstraints;
15           use MooseX::Meta::TypeConstraint::ForceCoercion;
16
17           # get any type constraint
18           my $tc = Str;
19
20           # declare one or more coercions for it
21           coerce $tc,
22               from Any,
23               via { ... };
24
25           # wrap the $tc to force coercion
26           my $coercing_tc = MooseX::Meta::TypeConstraint::ForceCoercion->new(
27               type_constraint => $tc,
28           );
29
30           # check a value against new type constraint. this will run the type
31           # coercions for the wrapped type, even if the value already passes
32           # validation before coercion. it will fail if the value couldn't be
33           # coerced
34           $coercing_tc->check('Affe');

DESCRIPTION

37       This class allows to wrap any "Moose::Meta::TypeConstraint" in a way
38       that will force coercion of the value when checking or validating a
39       value against it.
40

ATTRIBUTES

42   type_constraint
43       The type constraint to wrap. All methods except for "validate" and
44       "check" are delegated to the value of this attribute.
45

METHODS

47   check ($value)
48       Same as "Moose::Meta::TypeConstraint::check", except it will always try
49       to coerce $value before checking it against the actual type constraint.
50       If coercing fails the check will fail, too.
51
52   validate ($value, $coerced_ref?)
53       Same as "Moose::Meta::TypeConstraint::validate", except it will always
54       try to coerce $value before validating it against the actual type
55       constraint. If coercing fails the validation will fail, too.
56
57       If coercion was successful and a $coerced_ref references was passed,
58       the coerced value will be stored in that.
