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. | ||||
