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.

APPENDIX
The rest of the documentation details each of the object methods. Internal methods are usually preceded with a _
new
Title : new
Usage :
Function: Instantiates the persistence adaptor.
Example :
Returns :
Args :get_persistent_slots
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 updatedget_persistent_slot_values
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.instantiate_from_row
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.populate_from_row
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().get_unique_key_query
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.remove_children
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().get_classification
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 taxonget_common_name
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
