| 112 | =head1 NAME | ||||
| 113 | |||||
| 114 | Moose::Meta::TypeConstraint::Parameterizable - Type constraints which can take a parameter (ArrayRef) | ||||
| 115 | |||||
| 116 | =head1 VERSION | ||||
| 117 | |||||
| 118 | version 2.0602 | ||||
| 119 | |||||
| 120 | =head1 DESCRIPTION | ||||
| 121 | |||||
| 122 | This class represents a parameterizable type constraint. This is a | ||||
| 123 | type constraint like C<ArrayRef> or C<HashRef>, that can be | ||||
| 124 | parameterized and made more specific by specifying a contained | ||||
| 125 | type. For example, instead of just an C<ArrayRef> of anything, you can | ||||
| 126 | specify that is an C<ArrayRef[Int]>. | ||||
| 127 | |||||
| 128 | A parameterizable constraint should not be used as an attribute type | ||||
| 129 | constraint. Instead, when parameterized it creates a | ||||
| 130 | L<Moose::Meta::TypeConstraint::Parameterized> which should be used. | ||||
| 131 | |||||
| 132 | =head1 INHERITANCE | ||||
| 133 | |||||
| 134 | C<Moose::Meta::TypeConstraint::Parameterizable> is a subclass of | ||||
| 135 | L<Moose::Meta::TypeConstraint>. | ||||
| 136 | |||||
| 137 | =head1 METHODS | ||||
| 138 | |||||
| 139 | This class is intentionally not documented because the API is | ||||
| 140 | confusing and needs some work. | ||||
| 141 | |||||
| 142 | =head1 BUGS | ||||
| 143 | |||||
| 144 | See L<Moose/BUGS> for details on reporting bugs. | ||||
