Helper functions used by several schema classes.

Important Note: This package is located in the Schema.pm file as secondary package and it haven't a file for itself. Nevertheless, the use will be the same.

PACKAGE METHODS

create_properties

            

              
              
Usage: *::Util->create_properties( row => $self,
                                   properties => { baz => 2, foo => 'bar' },
                                   options => { cv_name => autocreate => 0, ...},
                                   prop_relation_name => 'organismprops',
                                 );
Desc : Chado has a number of <thing>prop tables with a similar
       structure.  This utility function is used by a number of
       modules to create properties in these kinds of tables.
Args : row => the DBIC row object to create properties for,
       prop_relation_name => the DBIC relation name for the
                             properties table to operate on,
                             e.g. 'featureprops',
       properties => hashref of { propname => value, ...},
       options => options hashref as:
           {
             autocreate => 0,
                (optional) boolean, if passed, automatically create cv,
                cvterm, and dbxref rows if one cannot be found for the
                given featureprop name.  Default false.
             cv_name => cv.name to use for the given featureprops.
                        Defaults to 'feature_property',
             db_name => db.name to use for autocreated dbxrefs,
                        default 'null',
             allow_duplicate_values => default false.
                 If true, allow duplicate instances of the same cvterm
                 and value in the properties of the feature.  Duplicate
                 values will have different ranks.
             dbxref_accession_prefix => optional, default
                                        'autocreated:',
             definitions => optional hashref of:
                 { cvterm_name => definition,
                 }
              to load into the cvterm table when autocreating cvterms
           }
Ret  : hashref of { propname => new row object in property table }
