107 | # ABSTRACT: The Moose Type Coercion metaclass | ||||
108 | |||||
- - | |||||
111 | =pod | ||||
112 | |||||
113 | =head1 NAME | ||||
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. | ||||
