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

graph

Title   : graph()
Usage   : $engine->graph();
Function: Returns the Graph this engine is based on
Returns : Graph
Args    :
