DESCRIPTION
From the MAGE-OM documentation for the "MassUnit" class:
Mass
INHERITANCE
Bio::MAGE::Measurement::MassUnit has the following superclasses:
· Bio::MAGE::Measurement::Unit
CLASS METHODS
The following methods can all be called without first having an
instance of the class via the
Bio::MAGE::Measurement::MassUnit->methodname() syntax.
new()
new(%args)
The object constructor "new()" accepts the following optional
named-value style arguments:
· unitNameCV
Sets the value of the "unitNameCV" attribute
· unitName
Sets the value of the "unitName" attribute (this attribute was
inherited from class "Bio::MAGE::Measurement::Unit").
· propertySets
Sets the value of the "propertySets" association (this
association was inherited from class "Bio::MAGE::Extendable").
The value must be of type: array of "Bio::MAGE::NameValueType".
$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.
"Bio::MAGE::Measurement::MassUnit" has the following attribute accessor
methods:
unitNameCV
Methods for the "unitNameCV" attribute.
From the MAGE-OM documentation:
$val = $massunit->setUnitNameCV($val)
The restricted setter method for the "unitNameCV" attribute.
"unitNameCV" is an enumerated attribute - it can only be set to
"undef" or one of the following values: kg g mg ug ng pg fg
other
Input parameters: the value to which the "unitNameCV" attribute
will be set
Return value: the current value of the "unitNameCV" attribute
Side effects: none
Exceptions: will call "croak()" if no input parameters are
specified, or if too many input parameters are specified, or if
$val is not one of the accepted enumeration values: kg g mg ug
ng pg fg other
$val = $massunit->getUnitNameCV()
The restricted getter method for the "unitNameCV" attribute.
Input parameters: none
Return value: the current value of the "unitNameCV" attribute :
an instance of type "kg g mg ug ng pg fg other".
Side effects: none
Exceptions: will call "croak()" if any input parameters are
specified
unitName
Methods for the "unitName" attribute.
From the MAGE-OM documentation:
The name of the unit.
$val = $massunit->setUnitName($val)
The restricted setter method for the "unitName" attribute.
Input parameters: the value to which the "unitName" attribute
will be set
Return value: the current value of the "unitName" attribute
Side effects: none
Exceptions: will call "croak()" if no input parameters are
specified, or if too many input parameters are specified
$val = $massunit->getUnitName()
The restricted getter method for the "unitName" attribute.
Input parameters: none
Return value: the current value of the "unitName" attribute
Side effects: none
Exceptions: will call "croak()" if any input parameters are
specified
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:
1. There must be exactly one item in the association, i.e. this is a
mandatory data field.
2. 0..1
There may be one item in the association, i.e. this is an optional
data field.
3. 1..N
There must be one or more items in the association, i.e. this is a
mandatory data field, with list cardinality.
4. 0..N
There may be one or more items in the association, i.e. this is an
optional data field, with list cardinality.
Bio::MAGE::Measurement::MassUnit has the following association accessor
methods:
propertySets
Methods for the "propertySets" association.
From the MAGE-OM documentation:
Allows specification of name/value pairs. Meant to primarily help
in-house, pipeline processing of instances by providing a place for
values that aren't part of the specification proper.
$array_ref = $massunit->setPropertySets($array_ref)
The restricted setter method for the "propertySets"
association.
Input parameters: the value to which the "propertySets"
association will be set : a reference to an array of objects of
type "Bio::MAGE::NameValueType"
Return value: the current value of the "propertySets"
association : a reference to an array of objects of type
"Bio::MAGE::NameValueType"
Side effects: none
Exceptions: will call "croak()" if no input parameters are
specified, or if too many input parameters are specified, or if
$array_ref is not a reference to an array class
"Bio::MAGE::NameValueType" instances
$array_ref = $massunit->getPropertySets()
The restricted getter method for the "propertySets"
association.
Input parameters: none
Return value: the current value of the "propertySets"
association : a reference to an array of objects of type
"Bio::MAGE::NameValueType"
Side effects: none
Exceptions: will call "croak()" if any input parameters are
specified
$val = $massunit->addPropertySets(@vals)
Because the propertySets association has list cardinality, it
may store more than one value. This method adds the current
list of objects in the propertySets association.
Input parameters: the list of values @vals to add to the
propertySets association. NOTE: submitting a single value is
permitted.
Return value: the number of items stored in the slot after
adding @vals
Side effects: none
Exceptions: will call "croak()" if no input parameters are
specified, or if any of the objects in @vals is not an instance
of class "Bio::MAGE::NameValueType"
sub initialize {
my $self = shift;
return 1;
}
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.
