METHODS

Top

__validate_type

  UMMF::MOF_1_3::Model::GeneralizableElement->__validate_type($value);

Returns true if $value is a valid representation of UMMF::MOF_1_3::Model::GeneralizableElement.

__typecheck

  UMMF::MOF_1_3::Model::GeneralizableElement->__typecheck($value, $msg);

Calls confess() with $msg if <UMMF::MOF_1_3::Model::GeneralizableElement-__validate_type($value)>> is false.

isaGeneralizableElement

Returns true if receiver is a UMMF::MOF_1_3::Model::GeneralizableElement. Other receivers will return false.

isaModel__GeneralizableElement

Returns true if receiver is a UMMF::MOF_1_3::Model::GeneralizableElement. Other receivers will return false. This is the fully qualified version of the isaGeneralizableElement method.

__model_name

Returns the UML Model name ('Model::GeneralizableElement') for an object or package of this Classifier.

__isAbstract

  $package->__isAbstract;

Returns 1.

__tangram_schema

  my $tangram_schema $obj_or_package->__tangram_schema

Returns a HASH ref that describes this Classifier for Tangram.

See UMMF::Export::Perl::Tangram

___initialize

Initialize all Attributes and AssociationEnds in a instance of this Classifier. Does not initalize slots in its Generalizations.

See also: __initialize.

__initialize

Initialize all slots in this Classifier and all its Generalizations.

See also: ___initialize.

__create

Calls all <<create>> Methods for this Classifier and all Generalizations.

See also: ___create.
