- $obj = class->new(%parameters)
-
The
new()
method is the class constructor.Parameters: if given a list of name/value parameters the corresponding slots, attributes, or associations will have their initial values set by the constructor.
Return value: It returns a reference to an object of the class.
Side effects: It invokes the
initialize()
method if it is defined by the class. - @names = class->get_slot_names()
-
The
get_slot_names()
method is used to retrieve the name of all slots defined in a given class.NOTE: the list of names does not include attribute or association names.
Return value: A list of the names of all slots defined for this class.
Side effects: none
- @name_list = get_attribute_names()
-
returns the list of attribute data members for this class.
- @name_list = get_association_names()
-
returns the list of association data members for this class.
- @class_list = get_superclasses()
-
returns the list of superclasses for this class.
- @class_list = get_subclasses()
-
returns the list of subclasses for this class.
- $name = class_name()
-
Returns the full class name for this class.
- $package_name = package_name()
-
Returns the base package name (i.e. no 'namespace::') of the package that contains this class.
- %assns = associations()
-
returns the association meta-information in a hash where the keys are the association names and the values are
Association
objects that provide the meta-information for the association.
INSTANCE METHODS
- $obj_copy = $obj->new()
-
When invoked with an existing object reference and not a class name, the
new()
method acts as a copy constructor - with the new object's initial values set to be those of the existing object.Parameters: No input parameters are used in the copy constructor, the initial values are taken directly from the object to be copied.
Return value: It returns a reference to an object of the class.
Side effects: It invokes the
initialize()
method if it is defined by the class. - $obj->set_slots(%parameters)
- $obj->set_slots(\@name_list, \@value_list)
-
The
set_slots()
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.Return value: none
Side effects: will call
croak()
if a slot_name is used that the class does not define. - @obj_list = $obj->get_slots(@name_list)
-
The
get_slots()
method is used to get the values of a number of slots at the same time.Return value: a list of instance objects
Side effects: none
- $val = $obj->set_slot($name,$val)
-
The
set_slot()
method sets the slot$name
to the value$val
Return value: the new value of the slot, i.e.
$val
Side effects: none
- $val = $obj->get_slot($name)
-
The
get_slot()
method is used to get the values of a number of slots at the same time.Return value: a single slot value, or undef if the slot has not been initialized.
Side effects: none
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.

ASSOCIATIONS
Associations are references to other classes. Associations in MAGE-OM have a cardinality that determines the minimum and maximum number of instances of the 'other' class that maybe included in the association:
There must be exactly one item in the association, i.e. this is a mandatory data field.
0..1
There may be one item in the association, i.e. this is an optional data field.
1..N
There must be one or more items in the association, i.e. this is a mandatory data field, with list cardinality.
0..N
There may be one or more items in the association, i.e. this is an optional data field, with list cardinality.

SLOTS, ATTRIBUTES, AND ASSOCIATIONS
In the Perl implementation of MAGE-OM classes, there are three types of class data members: slots
, attributes
, and associations
.
SLOTS
This API uses the term slot
to indicate a data member of the class that was not present in the UML model and is used for mainly internal purposes - use only if you understand the inner workings of the API. 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:
- $var = $obj->slot_name();
-
Retrieves the current value of the slot.
- $new_var = $obj->slot_name($new_var);
-
Store $new_var in the slot - the return value is also $new_var.
- @names = $obj->get_slot_names()
-
Returns the list of all slots in the class.
DATA CHECKING: No data type checking is made for these methods.
ATTRIBUTES AND ASSOCIATIONS
The terms attribute
and association
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:
- get*
-
Retrieves the current value.
NOTE: For associations, if the association has list cardinality, an array reference is returned.
DATA CHECKING: Ensure that no argument is provided.
- set*
-
Sets the current value, replacing any existing value.
NOTE: 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.
DATA CHECKING: 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.
- add*
-
NOTE: Only present in associations with list cardinality.
Appends a list of objects to any values that may already be stored in the association.
DATA CHECKING: Ensure that all arguments are of the correct MAGE-OM class.
GENERIC METHODS
The unified base class of all MAGE-OM classes, Bio::MAGE::Base
, provides a set of generic methods that will operate on slots, attributes, and associations:
- $val = $obj->get_slot($name)
- \@list_ref = $obj->get_slots(@name_list);
- $val = $obj->set_slot($name,$val)
- $obj->set_slots(%parameters)
- $obj->set_slots(\@name_list, \@value_list)
-
See elsewhere in this page for a detailed description of these methods.
