| 89 | =head1 NAME | ||||
| 90 | |||||
| 91 | Moose::Meta::TypeConstraint::Parameterizable - Type constraints which can take a parameter (ArrayRef) | ||||
| 92 | |||||
| 93 | =head1 DESCRIPTION | ||||
| 94 | |||||
| 95 | This class represents a parameterizable type constraint. This is a | ||||
| 96 | type constraint like C<ArrayRef> or C<HashRef>, that can be | ||||
| 97 | parameterized and made more specific by specifying a contained | ||||
| 98 | type. For example, instead of just an C<ArrayRef> of anything, you can | ||||
| 99 | specify that is an C<ArrayRef[Int]>. | ||||
| 100 | |||||
| 101 | A parameterizable constraint should not be used as an attribute type | ||||
| 102 | constraint. Instead, when parameterized it creates a | ||||
| 103 | L<Moose::Meta::TypeConstraint::Parameterized> which should be used. | ||||
| 104 | |||||
| 105 | =head1 INHERITANCE | ||||
| 106 | |||||
| 107 | C<Moose::Meta::TypeConstraint::Parameterizable> is a subclass of | ||||
| 108 | L<Moose::Meta::TypeConstraint>. | ||||
| 109 | |||||
| 110 | =head1 METHODS | ||||
| 111 | |||||
| 112 | This class is intentionally not documented because the API is | ||||
| 113 | confusing and needs some work. | ||||
| 114 | |||||
| 115 | =head1 BUGS | ||||
| 116 | |||||
| 117 | See L<Moose/BUGS> for details on reporting bugs. | ||||
