=head1 NAME

NACL::CS::SystemNodeCoredumpConfig

=head1 DESCRIPTION

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

=head1 ATTRIBUTES

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

=head1 METHODS

=head2 fetch

    my $SystemNodeCoredumpConfig_state   = NACL::CS::SystemNodeCoredumpConfig->fetch(command_interface => $ci, ...);
	my @SystemNodeCoredumpConfig_states = NACL::CS::SystemNodeCoredumpConfig->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 "coredump-config-get-iter" API for CMode ZAPI.

Invokes "options" command for 7Mode CLI.

=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.
