Bio::MAGE::Base - generic base class

MAGE::Base(3pm) User Contributed Perl Documentation MAGE::Base(3pm)

NAME

Bio::MAGE::Base - generic base class

SYNOPSIS

  use Bio::MAGE::Base;
  # create an empty instance
  my $obj = Bio::MAGE::Base->new();
  # create an instance and populate with data
  my $obj = Bio::MAGE::Base->new(attr1=>$val1, attr2=>$val2);
  # copy an existing instance
  my $obj_copy = $obj->new();

DESCRIPTION

The base class for all other Bio::MAGE classes

CLASS METHODS

The following methods can all be called without first having an instance of the class via the Namespace::Class-> methodname() syntax, i.e. the class name must be given as an argument to the method.
$obj = class->new(%params)
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.
The following methods can all be called with either the Namespace::Class-> methodname() and $obj->methodname() syntaxes.
@names = get_slot_names()
The "get_slot_names()" method is used to retrieve the name of all slots defined for a given object.
 
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

These methods must be invoked with the direct object syntax using an existing instance, i.e. $object-> method_name().
$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->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
