| 141 | =head1 NAME | ||||
| 142 | |||||
| 143 | Moose::Meta::TypeConstraint::Union - A union of Moose type constraints | ||||
| 144 | |||||
| 145 | =head1 DESCRIPTION | ||||
| 146 | |||||
| 147 | This metaclass represents a union of type constraints. A union takes | ||||
| 148 | multiple type constraints, and is true if any one of its member | ||||
| 149 | constraints is true. | ||||
| 150 | |||||
| 151 | =head1 INHERITANCE | ||||
| 152 | |||||
| 153 | C<Moose::Meta::TypeConstraint::Union> is a subclass of | ||||
| 154 | L<Moose::Meta::TypeConstraint>. | ||||
| 155 | |||||
| 156 | =over 4 | ||||
| 157 | |||||
| 158 | =item B<< Moose::Meta::TypeConstraint::Union->new(%options) >> | ||||
| 159 | |||||
| 160 | This creates a new class type constraint based on the given | ||||
| 161 | C<%options>. | ||||
| 162 | |||||
| 163 | It takes the same options as its parent. It also requires an | ||||
| 164 | additional option, C<type_constraints>. This is an array reference | ||||
| 165 | containing the L<Moose::Meta::TypeConstraint> objects that are the | ||||
| 166 | members of the union type. The C<name> option defaults to the names | ||||
| 167 | all of these member types sorted and then joined by a pipe (|). | ||||
| 168 | |||||
| 169 | The constructor sets the implementation of the constraint so that is | ||||
| 170 | simply calls C<check> on the newly created object. | ||||
| 171 | |||||
| 172 | Finally, the constructor also makes sure that the object's C<coercion> | ||||
| 173 | attribute is a L<Moose::Meta::TypeCoercion::Union> object. | ||||
| 174 | |||||
| 175 | =item B<< $constraint->type_constraints >> | ||||
| 176 | |||||
| 177 | This returns the array reference of C<type_constraints> provided to | ||||
| 178 | the constructor. | ||||
| 179 | |||||
| 180 | =item B<< $constraint->parents >> | ||||
| 181 | |||||
| 182 | This returns the same constraint as the C<type_constraints> method. | ||||
| 183 | |||||
| 184 | =item B<< $constraint->check($value) >> | ||||
| 185 | |||||
| 186 | =item B<< $constraint->validate($value) >> | ||||
| 187 | |||||
| 188 | These two methods simply call the relevant method on each of the | ||||
| 189 | member type constraints in the union. If any type accepts the value, | ||||
| 190 | the value is valid. | ||||
| 191 | |||||
| 192 | With C<validate> the error message returned includes all of the error | ||||
| 193 | messages returned by the member type constraints. | ||||
| 194 | |||||
| 195 | =item B<< $constraint->equals($type_name_or_object) >> | ||||
| 196 | |||||
| 197 | A type is considered equal if it is also a union type, and the two | ||||
| 198 | unions have the same member types. | ||||
| 199 | |||||
| 200 | =item B<< $constraint->is_a_type_of($type_name_or_object) >> | ||||
| 201 | |||||
| 202 | This returns true if any of the member type constraints return true | ||||
| 203 | for the C<is_a_type_of> method. | ||||
| 204 | |||||
| 205 | =item B<< $constraint->is_subtype_of >> | ||||
| 206 | |||||
| 207 | This returns true if any of the member type constraints return true | ||||
| 208 | for the C<is_a_subtype_of> method. | ||||
| 209 | |||||
| 210 | =item B<< $constraint->create_child_type(%options) >> | ||||
| 211 | |||||
| 212 | This returns a new L<Moose::Meta::TypeConstraint> object with the type | ||||
| 213 | as its parent. | ||||
