          get_child_terms(TermI term, RelationshipType predicate_terms): TermI
Function: Retrieves all ancestor terms of a given term, that satisfy
          a relationship among those that are specified in the second

Example : @leaf_terms = $obj->get_leaf_terms()
Returns : Array of TermI objects.
Args    :

get_root_terms

Title   : get_root_terms
Usage   : get_root_terms(): TermI

Example : @root_terms = $obj->get_root_terms()
Returns : Array of TermI objects.
Args    :

_filter_repeated

Title   : _filter_repeated
Usage   : @lst = $self->_filter_repeated(@old_lst);
Function: Removes repeated terms
Example :
Returns : List of unique TermI objects
Args    : List of TermI objects

get_all_terms

Title   : get_all_terms
Usage   : get_all_terms(): TermI
Function: Retrieves all terms currently stored in the ontology.
Example : @all_terms = $obj->get_all_terms()
Returns : Array of TermI objects.
Args    :

find_terms

Title   : find_terms
Usage   : ($term) = $oe->find_terms(-identifier => "SO:0000263");
Function: Find term instances matching queries for their attributes.

          This implementation can efficiently resolve queries by
          identifier.

Example :
Returns : an array of zero or more Bio::Ontology::TermI objects
Args    : Named parameters. The following parameters should be recognized
          by any implementations:

             -identifier    query by the given identifier
             -name          query by the given name

relationship_factory

Title   : relationship_factory
Usage   : $fact = $obj->relationship_factory()
Function: Get/set the object factory to be used when relationship
          objects are created by the implementation on-the-fly.

Example : 
Returns : value of relationship_factory (a Bio::Factory::ObjectFactoryI
          compliant object)
Args    : on set, a Bio::Factory::ObjectFactoryI compliant object

term_factory

Title   : term_factory
Usage   : $fact = $obj->term_factory()
Function: Get/set the object factory to be used when term objects are
          created by the implementation on-the-fly.

          Note that this ontology engine implementation does not
          create term objects on the fly, and therefore setting this
          attribute is meaningless.

Example : 
Returns : value of term_factory (a Bio::Factory::ObjectFactoryI
          compliant object)
Args    : on set, a Bio::Factory::ObjectFactoryI compliant object

_filter_unmarked

Title   : _filter_unmarked
Usage   : _filter_unmarked(TermI terms): TermI
Function: Removes the uninstantiated terms from the list of terms
Example :
Returns : array of fully instantiated TermI objects
Args    : array of TermI objects

remove_term_by_id

Title   : remove_term_by_id
Usage   : remove_term_by_id(String id): TermI
Function: Removes TermI object from the ontology engine using the
          string id as an identifier. Current implementation does not
          enforce consistency of the relationships using that term.
Example : $term = $soe->remove_term_by_id($id);
Returns : Object of class TermI or undef if not found.
Args    : The string identifier of a term.

to_string

Title   : to_string
Usage   : print $sv->to_string();
Function: Currently returns formatted string containing the number of
          terms and number of relationships from the ontology engine.
Example : print $sv->to_string();
Returns :
Args    :

_unique_termid

Title   : _unique_termid
Usage   :
Function: Returns a string that can be used as ID using fail-over
          approaches. 

          If the identifier attribute is not set, it uses the
          combination of name and ontology name, provided both are
          set. If they are not, it returns the name alone.

          Note that this is a private method. Call from inheriting
          classes but not from outside.

Example :
Returns : a string
Args    : a Bio::Ontology::TermI compliant object
