Bio::DB::BioSQL::SpeciesAdaptor - DESCRIPTION of Object
Give standard usage here
Species DB adaptor
User feedback is an integral part of the evolution of this and other Bioperl modules. Send your comments and suggestions preferably to one of the Bioperl mailing lists. Your participation is much appreciated.
Please direct usage questions or support issues to the mailing list:
rather than to the module maintainer directly. Many experienced and reponsive experts will be able look at the problem and quickly address it. Please include a thorough description of the problem with code and data examples if at all possible.
Report bugs to the Bioperl bug tracking system to help us keep track the bugs and their resolution. Bug reports can be submitted via email or the web:

The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
Title : new Usage : Function: Instantiates the persistence adaptor. Example : Returns : Args :
Title : get_persistent_slots Usage : Function: Get the slots of the object that map to attributes in its respective entity in the datastore. Slots should be methods callable without an argument. This is a strictly abstract method. A derived class MUST override it to return something meaningful. Example : Returns : an array of method names constituting the serializable slots Args : the object about to be inserted or updated
Title : get_persistent_slot_values Usage : Function: Obtain the values for the slots returned by get_persistent_slots(), in exactly that order. The reason this method is here is that sometimes the actual slot values need to be post-processed to yield the value that gets actually stored in the database. E.g., slots holding arrays will need some kind of join function applied. Another example is if the method call needs additional arguments. Supposedly the adaptor for a specific interface knows exactly what to do here. Since there is also populate_from_row() the adaptor has full control over mapping values to a version that is actually stored. Example : Returns : A reference to an array of values for the persistent slots of this object. Individual values may be undef. Args : The object about to be serialized. A reference to an array of foreign key objects if not retrievable from the object itself.
Title : instantiate_from_row Usage : Function: Instantiates the class this object is an adaptor for, and populates it with values from columns of the row. This implementation call populate_from_row() to do the real job. Example : Returns : An object, or undef, if the row contains no values Args : A reference to an array of column values. The first column is the primary key, the other columns are expected to be in the order returned by get_persistent_slots(). Optionally, the object factory to be used for instantiating the proper class. The adaptor must be able to instantiate a default class if this value is undef.
Title : populate_from_row Usage : Function: Instantiates the class this object is an adaptor for, and populates it with values from columns of the row. Usually a derived class will instantiate the proper class and pass it on to populate_from_row(). This method MUST be overridden by a derived object. Example : Returns : An object, or undef, if the row contains no values Args : The object to be populated. A reference to an array of column values. The first column is the primary key, the other columns are expected to be in the order returned by get_persistent_slots().
Title : get_unique_key_query Usage : Function: Obtain the suitable unique key slots and values as determined by the attribute values of the given object and the additional foreign key objects, in case foreign keys participate in a UK. Example : Returns : One or more references to hash(es) where each hash represents one unique key, and the keys of each hash represent the names of the object's slots that are part of the particular unique key and their values are the values of those slots as suitable for the key. Args : The object with those attributes set that constitute the chosen unique key (note that the class of the object will be suitable for the adaptor). A reference to an array of foreign key objects if not retrievable from the object itself.
Title : remove_children Usage : Function: This method is to cascade deletes in maintained objects. We just return TRUE here. Example : Returns : TRUE on success and FALSE otherwise Args : The persistent object that was just removed from the database. Additional (named) parameter, as passed to remove().
Title : get_classification Usage : Function: Returns the classification array for a taxon as identified by its primary key. Example : Returns : a reference to an array of two-element arrays, where the first element contains the name of the node and the second element denotes its rank Args : the primary key of the taxon
Title : get_common_name Usage : Function: Get the common name for a taxon as identified by its primary key. Example : Returns : a string denoting the common name Args : the primary key of the taxon
