=head1 NAME

NACL::CS::SystemNodeAutosupportDestinations

=head1 DESCRIPTION

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

=head1 ATTRIBUTES

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

=over

=item C<< "node" >>

Filled in for CMode CLI/ZAPI

Maps to:

CMode ZAPI:

For "requested_fields", "filter" and Output mapping:

 <autosupport-destinations-info>
	<node-name>$value</node-name>
 </autosupport-destinations-info>

=item C<< "destinations" >>

(Array)

Note that for array fields, the accessor method can be invoked in either
scalar or list context.
 my $destinations = $obj->destinations();
 # $destinations contains a reference to the array of values
 my @destinations = $obj->destinations();
 # @destinations contains the array of values

Filled in for CMode CLI/ZAPI

Maps to:

CMode ZAPI:

For "requested_fields", "filter" and Output mapping:

 <autosupport-destinations-info>
	<string>
		<destinations>@values</destinations>
	</string>
 </autosupport-destinations-info>

=head1 METHODS

=head2 fetch

    my $SystemNodeAutosupportDestinations_state = NACL::CS::SystemNodeAutosupportDestinations->fetch(command_interface => $ci, ...);
   my @SystemNodeAutosupportDestinations_states = NACL::CS::SystemNodeAutosupportDestinations->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, 7Mode CLI.

Invokes "autosupport-destinations-get-iter" API for CMode ZAPI.

Invokes "autosupport destinations show" command for 7Mode CLI.
