Retrieve the PHP_UML_Metamodel_Package object related to a package path (ie, to a qualified name, like A\B\C).
Relies on the model->$packages, when references are still named (= before their resolution)
Parameters:
Recursively replaces all the "named types" by a proper "reference" to a
typed element. This impacts:
- the extended classes and implemented classes (through their
EMOF-"superClass" and "implements" relations)
- the function parameters (through their EMOF-"type" attribute)
- the properties in classes (through their EMOF-"type" attribute)
Overridden in child classes as:
- PHP_UML_Metamodel_TypeResolverByName::resolve()
- PHP_UML_Metamodel_TypeResolverById::resolve()
Parameters:
