=head1 DESCRIPTION

C<NACL::CS::JobQueue> is a derived class of

The individual pieces of data that are part of the  state of the JobQueue
element are the attributes of the JobQueue ComponentState.

    my $JobQueue_state   = NACL::CS::JobQueue->fetch(command_interface => $ci, ...);
	my @JobQueue_states = NACL::CS::JobQueue->fetch(command_interface => $ci, ...);

(Class method)
Discovers which elements are present and returns their state in ComponentState
objects. Called in scalar context it returns only one state object, in list
context it returns all state objects.
See L<NACL::CS::ComponentState|lib-NACL-CS-ComponentState-pm/fetch> for a
more detailed description along with a complete explanation of the options
it accepts.

Supports CMode CLI/ZAPI.

Invokes "job-queue-get-iter" API for CMode ZAPI.

=item C<NACL::Exceptions::NoElementsFound>

When there are no elements matching the query specified or elements of that type
doesn't exist, then this exception will be thrown.
