Design Specs: Evidence Handling

API

the base function

by calling the _get_evidence($node,$type) subroutine in lib/API/Object.pm

argument $type is optional. If specified, only this type of evidence is retrieved.

returns a hash reference containing all the types of evidences to the right of the node

   code snippet: 
 	$data{$type}{$evidence}{id} = "$evidence"; 

$data{$type}{$evidence}{label} = "$label"; $data{$type}{$evidence}{class} = lc($class) if(defined $class);

      ...
       return %data ? \%data :undef;

use it in object model module

 e.g. in lib/API/Object/Gene.pm
 sub gene_ontology {

  push @{ $data{$facet} }, {
               method        => $1,
               evidence_code => {text=>"$evidence_code",evidence=>$self->_get_evidence($evidence_code)},
               term          => $self->_pack_obj($go_term),
           };
 }
