114 |  |  |  |  |
115 |  |  |  |  | Moose::Meta::TypeCoercion - The Moose Type Coercion metaclass
116 |  |  |  |  |
117 |  |  |  |  | =head1 VERSION
118 |  |  |  |  |
119 |  |  |  |  | version 2.0602
120 |  |  |  |  |
121 |  |  |  |  | =head1 DESCRIPTION
122 |  |  |  |  |
123 |  |  |  |  | A type coercion object is basically a mapping of one or more type
124 |  |  |  |  | constraints and the associated coercions subroutines.
125 |  |  |  |  |
126 |  |  |  |  | It's unlikely that you will need to instantiate an object of this
127 |  |  |  |  | class directly, as it's part of the deep internals of Moose.
128 |  |  |  |  |
129 |  |  |  |  | =head1 METHODS
130 |  |  |  |  |
131 |  |  |  |  | =over 4
132 |  |  |  |  |
133 |  |  |  |  | =item B<< Moose::Meta::TypeCoercion->new(%options) >>
134 |  |  |  |  |
135 |  |  |  |  | Creates a new type coercion object, based on the options provided.
136 |  |  |  |  |
137 |  |  |  |  | =over 8
138 |  |  |  |  |
139 |  |  |  |  | =item * type_constraint
140 |  |  |  |  |
141 |  |  |  |  | This is the L<Moose::Meta::TypeConstraint> object for the type that is
142 |  |  |  |  | being coerced I<to>.
143 |  |  |  |  |
144 |  |  |  |  | =back
145 |  |  |  |  |
146 |  |  |  |  | =item B<< $coercion->type_coercion_map >>
147 |  |  |  |  |
148 |  |  |  |  | This returns the map of type constraints to coercions as an array
149 |  |  |  |  | reference. The values of the array alternate between type names and
150 |  |  |  |  | subroutine references which implement the coercion.
151 |  |  |  |  |
152 |  |  |  |  | The value is an array reference because coercions are tried in the
153 |  |  |  |  | order they are added.
154 |  |  |  |  |
155 |  |  |  |  | =item B<< $coercion->type_constraint >>
156 |  |  |  |  |
157 |  |  |  |  | This returns the L<Moose::Meta::TypeConstraint> that was passed to the
158 |  |  |  |  | constructor.
159 |  |  |  |  |
160 |  |  |  |  | =item B<< $coercion->has_coercion_for_type($type_name) >>
161 |  |  |  |  |
162 |  |  |  |  | Returns true if the coercion can coerce the named type.
163 |  |  |  |  |
164 |  |  |  |  | =item B<< $coercion->add_type_coercions( $type_name => $sub, ... ) >>
165 |  |  |  |  |
166 |  |  |  |  | This method takes a list of type names and subroutine references. If
167 |  |  |  |  | the coercion already has a mapping for a given type, it throws an
168 |  |  |  |  | exception.
169 |  |  |  |  |
170 |  |  |  |  | Coercions are actually
171 |  |  |  |  |
172 |  |  |  |  | =item B<< $coercion->coerce($value) >>
173 |  |  |  |  |
174 |  |  |  |  | This method takes a value and applies the first valid coercion it
175 |  |  |  |  | finds.
176 |  |  |  |  |
177 |  |  |  |  | This means that if the value could belong to more than type in the
178 |  |  |  |  | coercion object, the first coercion added is used.
179 |  |  |  |  |
180 |  |  |  |  | =item B<< Moose::Meta::TypeCoercion->meta >>
181 |  |  |  |  |
182 |  |  |  |  | This will return a L<Class::MOP::Class> instance for this class.
183 |  |  |  |  |
