| 146 | |||||

| 149 | =pod | ||||
| 150 | |||||
| 151 | =head1 NAME | ||||
| 152 | |||||
| 153 | Class::MOP::Method - Method Meta Object | ||||
| 154 | |||||
| 155 | =head1 VERSION | ||||
| 156 | |||||
| 157 | version 2.0602 | ||||
| 158 | |||||
| 159 | =head1 DESCRIPTION | ||||
| 160 | |||||
| 161 | The Method Protocol is very small, since methods in Perl 5 are just | ||||
| 162 | subroutines in a specific package. We provide a very basic | ||||
| 163 | introspection interface. | ||||
| 164 | |||||
| 165 | =head1 METHODS | ||||
| 166 | |||||
| 167 | =over 4 | ||||
| 168 | |||||
| 169 | =item B<< Class::MOP::Method->wrap($code, %options) >> | ||||
| 170 | |||||
| 171 | This is the constructor. It accepts a method body in the form of | ||||
| 172 | either a code reference or a L<Class::MOP::Method> instance, followed | ||||
| 173 | by a hash of options. | ||||
| 174 | |||||
| 175 | The options are: | ||||
| 176 | |||||
| 177 | =over 8 | ||||
| 178 | |||||
| 179 | =item * name | ||||
| 180 | |||||
| 181 | The method name (without a package name). This is required if C<$code> | ||||
| 182 | is a coderef. | ||||
| 183 | |||||
| 184 | =item * package_name | ||||
| 185 | |||||
| 186 | The package name for the method. This is required if C<$code> is a | ||||
| 187 | coderef. | ||||
| 188 | |||||
| 189 | =item * associated_metaclass | ||||
| 190 | |||||
| 191 | An optional L<Class::MOP::Class> object. This is the metaclass for the | ||||
| 192 | method's class. | ||||
| 193 | |||||
| 194 | =back | ||||
| 195 | |||||
| 196 | =item B<< $metamethod->clone(%params) >> | ||||
| 197 | |||||
| 198 | This makes a shallow clone of the method object. In particular, | ||||
| 199 | subroutine reference itself is shared between all clones of a given | ||||
| 200 | method. | ||||
| 201 | |||||
| 202 | When a method is cloned, the original method object will be available | ||||
| 203 | by calling C<original_method> on the clone. | ||||
| 204 | |||||
| 205 | =item B<< $metamethod->body >> | ||||
| 206 | |||||
| 207 | This returns a reference to the method's subroutine. | ||||
| 208 | |||||
| 209 | =item B<< $metamethod->name >> | ||||
| 210 | |||||
| 211 | This returns the method's name | ||||
| 212 | |||||
| 213 | =item B<< $metamethod->package_name >> | ||||
| 214 | |||||
| 215 | This returns the method's package name. | ||||
| 216 | |||||
| 217 | =item B<< $metamethod->fully_qualified_name >> | ||||
| 218 | |||||
| 219 | This returns the method's fully qualified name (package name and | ||||
| 220 | method name). | ||||
| 221 | |||||
| 222 | =item B<< $metamethod->associated_metaclass >> | ||||
| 223 | |||||
| 224 | This returns the L<Class::MOP::Class> object for the method, if one | ||||
| 225 | exists. | ||||
| 226 | |||||
| 227 | =item B<< $metamethod->original_method >> | ||||
| 228 | |||||
| 229 | If this method object was created as a clone of some other method | ||||
| 230 | object, this returns the object that was cloned. | ||||
| 231 | |||||
| 232 | =item B<< $metamethod->original_name >> | ||||
| 233 | |||||
| 234 | This returns the method's original name, wherever it was first | ||||
| 235 | defined. | ||||
| 236 | |||||
| 237 | If this method is a clone of a clone (of a clone, etc.), this method | ||||
| 238 | returns the name from the I<first> method in the chain of clones. | ||||
| 239 | |||||
| 240 | =item B<< $metamethod->original_package_name >> | ||||
| 241 | |||||
| 242 | This returns the method's original package name, wherever it was first | ||||
| 243 | defined. | ||||
| 244 | |||||
| 245 | If this method is a clone of a clone (of a clone, etc.), this method | ||||
| 246 | returns the package name from the I<first> method in the chain of | ||||
| 247 | clones. | ||||
| 248 | |||||
| 249 | =item B<< $metamethod->original_fully_qualified_name >> | ||||
| 250 | |||||
| 251 | This returns the method's original fully qualified name, wherever it | ||||
| 252 | was first defined. | ||||
| 253 | |||||
| 254 | If this method is a clone of a clone (of a clone, etc.), this method | ||||
| 255 | returns the fully qualified name from the I<first> method in the chain | ||||
| 256 | of clones. | ||||
| 257 | |||||
| 258 | =item B<< $metamethod->is_stub >> | ||||
| 259 | |||||
| 260 | Returns true if the method is just a stub: | ||||
| 261 | |||||
| 262 | sub foo; | ||||
| 263 | |||||
| 264 | =item B<< $metamethod->attach_to_class($metaclass) >> | ||||
| 265 | |||||
| 266 | Given a L<Class::MOP::Class> object, this method sets the associated | ||||
| 267 | metaclass for the method. This will overwrite any existing associated | ||||
| 268 | metaclass. | ||||
| 269 | |||||
| 270 | =item B<< $metamethod->detach_from_class >> | ||||
| 271 | |||||
| 272 | Removes any associated metaclass object for the method. | ||||
| 273 | |||||
| 274 | =item B<< $metamethod->execute(...) >> | ||||
| 275 | |||||
| 276 | This executes the method. Any arguments provided will be passed on to | ||||
| 277 | the method itself. | ||||
| 278 | |||||
| 279 | =item B<< Class::MOP::Method->meta >> | ||||
| 280 | |||||
| 281 | This will return a L<Class::MOP::Class> instance for this class. | ||||
| 282 | |||||
| 283 | It should also be noted that L<Class::MOP> will actually bootstrap | ||||
| 284 | this module by installing a number of attribute meta-objects into its | ||||
| 285 | metaclass. | ||||
