Bio::Ontology::RelationshipType(3) a relationship type for an ontology

SYNOPSIS


#

DESCRIPTION

This class can be used to model various types of relationships (such as ``IS_A'', ``PART_OF'', ``CONTAINS'', ``FOUND_IN'', ``RELATED_TO'').

This class extends Bio::Ontology::Term, so it essentially is-a Bio::Ontology::TermI. In addition, all methods are overridden such as to make the object immutable.

 Usage   : $IS_A       = Bio::Ontology::RelationshipType->get_instance( "IS_A" );
           $PART_OF    = Bio::Ontology::RelationshipType->get_instance( "PART_OF" );
           $RELATED_TO = Bio::Ontology::RelationshipType->get_instance( "RELATED_TO" );
           $CONTAINS   = Bio::Ontology::RelationshipType->get_instance( "CONTAINS" );
           $FOUND_IN   = Bio::Ontology::RelationshipType->get_instance( "FOUND_IN" );
 Function: Factory method to create instances of RelationshipType
 Returns : [Bio::Ontology::RelationshipType]
 Args    : "IS_A" or "PART_OF" or "CONTAINS" or "FOUND_IN" or 
           "RELATED_TO" [scalar]

 Returns :
 Args    :

equals

 Title   : equals
 Usage   : if ( $type->equals( $other_type ) ) { ...
 Function: Compares this type to another one, based on string "eq" of

 Title   : is_obsolete
 Usage   : $term->is_obsolete( 1 );
           or
           if ( $term->is_obsolete() )
 Function: Set/get for the immutable obsoleteness of this Type.
 Returns : the obsoleteness [0 or 1].
