The value must be of type: array of C. =item * propertySets Sets the value of the C association (this association was inherited from class C).

The value must be of type: instance of C. =back =item $obj = class->new(%parameters) The C method is the class constructor. B: if given a list of name/value parameters the corresponding slots, attributes, or associations will have their initial values set by the constructor. B: It returns a reference to an object of the class. B: It invokes the C method if it is defined by the class. =cut # # code for new() inherited from Base.pm # =item @names = class->get_slot_names() The C method is used to retrieve the name of all slots defined in a given class. B: the list of names does not include attribute or association names. B: A list of the names of all slots defined for this class. B: none =cut # # code for get_slot_names() inherited from Base.pm # =item @name_list = get_attribute_names() returns the list of attribute data members for this class. =cut # # code for get_attribute_names() inherited from Base.pm # =item @name_list = get_association_names() returns the list of association data members for this class. =cut # # code for get_association_names() inherited from Base.pm # =item @class_list = get_superclasses() returns the list of superclasses for this class. =cut # # code for get_superclasses() inherited from Base.pm # =item @class_list = get_subclasses() returns the list of subclasses for this class. =cut # # code for get_subclasses() inherited from Base.pm # =item $name = class_name() Returns the full class name for this class. =cut # # code for class_name() inherited from Base.pm # =item $package_name = package_name() Returns the base package name (i.e. no 'namespace::') of the package that contains this class. =cut # # code for package_name() inherited from Base.pm # =item %assns = associations() returns the association meta-information in a hash where the keys are the association names and the values are C objects that provide the meta-information for the association. =cut # # code for associations() inherited from Base.pm # =back =head1 INSTANCE METHODS =item $obj_copy = $obj->new() When invoked with an existing object reference and not a class name, the C method acts as a copy constructor - with the new object's initial values set to be those of the existing object. B: No input parameters are used in the copy constructor, the initial values are taken directly from the object to be copied. B: It returns a reference to an object of the class. B: It invokes the C method if it is defined by the class. =cut # # code for new() inherited from Base.pm # =item $obj->set_slots(%parameters) =item $obj->set_slots(\@name_list, \@value_list) The C method is used to set a number of slots at the same time. It has two different invocation methods. The first takes a named parameter list, and the second takes two array references. B: none B: will call C if a slot_name is used that the class does not define. =cut # # code for set_slots() inherited from Base.pm # =item @obj_list = $obj->get_slots(@name_list) The C method is used to get the values of a number of slots at the same time. B: a list of instance objects B: none =cut # # code for get_slots() inherited from Base.pm # =item $val = $obj->set_slot($name,$val) The C method sets the slot C<$name> to the value C<$val> B: the new value of the slot, i.e. C<$val> B: none =cut # # code for set_slot() inherited from Base.pm # =item $val = $obj->get_slot($name) The C method is used to get the values of a number of slots at the same time. B: a single slot value, or undef if the slot has not been initialized. B: none =cut # # code for get_slot() inherited from Base.pm # =head2 ATTRIBUTES Attributes are simple data types that belong to a single instance of a class. In the Perl implementation of the MAGE-OM classes, the interface to attributes is implemented using separate setter and getter methods for each attribute. C has the following attribute accessor methods: =over =item name Methods for the C attribute. From the MAGE-OM documentation: The potentially ambiguous common identifier. =over =item $val = $quantitationtypedimension->setName($val) The restricted setter method for the C attribute.

Most often slots are used by generic methods such as those in the XML writing and reading classes. Slots are implemented using unified getter/setter methods: =over =item $var = $obj->slot_name(); Retrieves the current value of the slot. =item $new_var = $obj->slot_name($new_var); Store $new_var in the slot - the return value is also $new_var. =item @names = $obj->get_slot_names() Returns the list of all slots in the class. =back B: No data type checking is made for these methods. =head2 ATTRIBUTES AND ASSOCIATIONS The terms C and C indicate data members of the class that were specified directly from the UML model. In the Perl implementation of MAGE-OM classes, association and attribute accessors are implemented using three separate methods: =over =item get* Retrieves the current value. B: For associations, if the association has list cardinality, an array reference is returned. B: Ensure that no argument is provided. =item set* Sets the current value, B any existing value. B: For associations, if the association has list cardinality, the argument must be an array reference. Because of this, you probably should be using the add* methods. B: For attributes, ensure that a single value is provided as the argument. For associations, if the association has list cardinality, ensure that the argument is a reference to an array of instances of the correct MAGE-OM class, otherwise ensure that there is a single argument of the correct MAGE-OM class. =item add* B: Only present in associations with list cardinality. Appends a list of objects to any values that may already be stored in the association. B: Ensure that all arguments are of the correct MAGE-OM class. =back =head2 GENERIC METHODS The unified base class of all MAGE-OM classes, C, provides a set of generic methods that will operate on slots, attributes, and associations: =over =item $val = $obj->get_slot($name) =item \@list_ref = $obj->get_slots(@name_list); =item $val = $obj->set_slot($name,$val) =item $obj->set_slots(%parameters) =item $obj->set_slots(\@name_list, \@value_list) See elsewhere in this page for a detailed description of these methods. =back =cut =head1 BUGS Please send bug reports to the project mailing list: (mged-mage 'at' lists 'dot' sf 'dot' net) =head1 AUTHOR Jason E.
