=head1 NAME

NACL::CS::QosSettingsWorkloadTop

=head1 DESCRIPTION

C<NACL::CS::QosSettingsWorkloadTop> is a derived class of
L<NACL::CS::ComponentState::ONTAP|lib-NACL-CS-ComponentState-ONTAP-pm>. It represents the
state of an ONTAP QosSettingsWorkloadTop.  A related class is
L<NACL::C::QosSettingsWorkloadTop|lib-NACL-C-QosSettingsWorkloadTop-pm>, which represents access
to an ONTAP QosSettingsWorkloadTop.

=head1 ATTRIBUTES

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

Additionally, the command_interface used to obtain the ComponentState object is 
also an attribute of the object. This makes it easier to obtain the component
object corresponding to the CS object, using 
L<get_component_instance|lib-NACL-CS-ComponentState-pm/get_component_instance>.

=over

=item command_interface

The command_interface with which the CS object was obtained. (Available in
all CS objects regardless of requested_fields and the mode/interface)

=item C<< max_workloads >>

Filled in for CMode CLI

=head1 METHODS

=head2 fetch

    my $QosSettingsWorkloadTop_state  = NACL::CS::QosSettingsWorkloadTop->fetch(command_interface => $ci, ...);
(Class method)
Discovers which elements are present and returns their state in ComponentState
objects. This being a "singleton" table (i.e. one which can only have one
row) is callable only in scalar context.
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.

Uses a CMode CLI APISet.

=item Exceptions

=over

=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.
