NAME

InterMine::Model::ClassDescriptor - represents a class in an InterMine model

SYNOPSIS

use InterMine::Model::ClassDescriptor;

...
my $cd = InterMine::Model::ClassDescriptor->create(
           "Gene" => (
               model => $model,
               parents => ["BioEntity"]
           )
       );

DESCRIPTION

Objects of this class contain the metadata that describes a class in an InterMine model. Each class has a name, parent classes/interfaces and any number of attributes, references and collections.

InterMine class descriptors are sub classes of Moose::Meta::Class, and thus Class::MOP::Class. Please refer to these packages for further documentation.

CLASS METHODS

create( $name | $name, %attributes | $name, \%attributes | \%attributes )

The class constructor inherited from Moose::Meta::Class.

Usage   : my $cd = InterMine::Model::ClassDescriptor->create(
               "Gene" => (
                   model => $model,
                   parents => ["BioEntity"]
               )
           );

Function: create a new ClassDescriptor object
Args    : model   - the InterMine::Model that this class is a part of
          name    - the class name
          parents - a list of the classes and interfaces that this 
                    classes extends

In most normal use cases, the typical user should NOT need to call this method. It is used internally when parsing the model to build up the list of classes.

INSTANCE ATTRIBUTES

name | package

  • unqualified_name

    returns the (unqualified) name of the class this class descriptor represents.

    $gene_meta->unqualified_name
# "Gene"

  • package

    This is the attribute inherited from Moose::Meta::Class, and returns the full qualified class name that perl refers to the class internally as.

    $gene_meta->name
# InterMine::genomic::FlyMine::Gene

own_fields

Fields that belong to this class directly.

add_own_field($field)

Add a field to the list

get_own_fields

Get the full list of fields declared in this class.

fieldhash

The map of fields for this class, including inherited fields. It has the following accessors:

set_field($name, $field)

Set a field in the map

get_field_by_name($name)

Retrieve the named field.

fields

Retrieve all fields as a list

valid_field($name)

Returns true if there is a field of this name

attributes

Return the fields that are instances of InterMine::Model::Attribute. This is not to be confused with Class::MOP's get_all_attributes.

references

Return all the fields that are instances of InterMine::Model::Reference, but not the subclass InterMine::Model::Collection.

collections

Return all the fields that are instances of InterMine::Model::Collection.

parents

The names of the immediate ancestors of this class.

parental_class_descriptors

The parents as a list of class objects.

Usage   : @parent_cds = $cd->parental_class_descriptors();
Function: return a list of the ClassDescriptor objects for the
          classes/interfaces that this class directly extends
Note    : Calling this method retrives the parents from the model
          and also sets up superclass relationships
          in Moose. It should not be called until the Model is completely
          parsed. It is called automatically once the model has been 
          parsed.
Args    : none

INSTANCE METHODS

new_object

The instantiation method inherited from Moose::Meta::Class. You should not normally need to use this directly. Instead call the make_new method in InterMine::Model.

get_ancestors

The full inheritance list, including all ancestors in the model.

add_field(FieldDescriptor $field, Bool own)

Add a field to the class. If there is already a field of the same name, it will not be added twice. Setting the boolean flag "own" marks this field as originating in this class

See also: InterMine::Model->_fix_class_descriptors

sub_class_of

Usage   : if ($class_desc->sub_class_of($other_class_desc)) { ... }
Function: Returns true if and only if this class is a sub-class 
          of the given class or is the same class
Args    : $other_class_desc - a ClassDescriptor, or name of one

to_string

The stringification of a class-descriptor. By default, it stringifies to its unqualified_name.
