=head1 NAME
Koha::Illrequest - Koha Illrequest Object class
=head1 (Re)Design
An ILLRequest consists of two parts; the Illrequest Koha::Object, and a series
of related Illrequestattributes.
The former encapsulates the basic necessary information that any ILL requires
to be usable in Koha. The latter is a set of additional properties used by
one of the backends.
The former subsumes the legacy "Status" object. The latter remains
encapsulated in the "Record" object.
TODO:
- Anything invoking the ->status method; annotated with:
+ # Old use of ->status !
=head1 API
=head2 Backend API Response Principles
All methods should return a hashref in the following format:
=over
=item * error
This should be set to 1 if an error was encountered.
=item * status
The status should be a string from the list of statuses detailed below.
=item * message
The message is a free text field that can be passed on to the end user.
=item * value
The value returned by the method.
=back
=head2 Interface Status Messages
=over
=item * branch_address_incomplete
An interface request has determined branch address details are incomplete.
=item * cancel_success
The interface's cancel_request method was successful in cancelling the
Illrequest using the API.
=item * cancel_fail
The interface's cancel_request method failed to cancel the Illrequest using
the API.
=item * unavailable
The interface's request method returned saying that the desired item is not
available for request.
=back

=head3 statusalias
my $statusalias = $request->statusalias;
Returns a request's status alias, as a Koha::AuthorisedValue instance
or implicit undef. This is distinct from status_alias, which only returns
the value in the status_alias column, this method returns the entire
AuthorisedValue object

that is implemented in core, but might not be supported by a given backend.
in capabilities & custom_capability, capability refers to entries in the
status_graph (after union between backend and core).

capabilities & custom_capability and their callers.

=head3 _status_graph_union
my $status_graph = $illrequest->_status_graph_union($origin, $new_graph);
Return a new status_graph, the result of merging $origin & new_graph. This is
operation is a union over the sets defied by the two graphs.
Each entry in $new_graph is added to $origin. We do not provide a syntax for
'subtraction' of entries from $origin.
Whilst it is not intended that this works, you can override entries in $origin
with entries with the same key in $new_graph. This can lead to problematic
behaviour when $new_graph adds an entry, which modifies a dependent entry in
$origin, only for the entry in $origin to be replaced later with a new entry
from $new_graph.
NOTE: this procedure does not "re-link" entries in $origin or $new_graph,
i.e. each of the graphs need to be correct at the outset of the operation.

### Core API methods
=head3 capabilities

Return a hashref mapping methods to operation names supported by the queried
backend.
Example return value:

that is implemented in core, but might not be supported by a given backend.
in capabilities & custom_capability, capability refers to entries in the
status_graph (after union between backend and core).
The easiest way to fix this would be to fix the terminology in
capabilities & custom_capability and their callers.

LimitRules are derived from koha-conf.xml:
