=head1 NAME

NACL::CS::EventRoute

=head1 DESCRIPTION

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

=head1 ATTRIBUTES

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

=item C<< "messagename" >>

Filled in for CMode CLI/ZAPI.

    <message-name>$value</message-name>
 </ems-routing-info>

=item C<< "timethreshold" >>

Filled in for CMode CLI/ZAPI.

Maps to:

CM ZAPI:

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

 <ems-routing-info>
    <time-threshold>$value</time-threshold>
 </ems-routing-info>

=item C<< "description" >>

Filled in for CMode CLI/ZAPI.

Maps to:

CM ZAPI:

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

 <ems-routing-info>
    <description>$value</description>
 </ems-routing-info>

=item C<< "frequencythreshold" >>

Filled in for CMode CLI/ZAPI.

Maps to:

CM ZAPI:

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

 <ems-routing-info>
    <frequency-threshold>$value</frequency-threshold>
 </ems-routing-info>

=item C<< "action" >>

Filled in for CMode CLI/ZAPI.

Maps to:

CM ZAPI:

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

 <ems-routing-info>

 </ems-routing-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:

CM ZAPI:

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

 <ems-routing-info>
    <destinations>
        <ems-destination>@values</ems-destination>
    </destinations>
 </ems-routing-info>

=item C<< "severity" >>

Filled in for CMode CLI/ZAPI.

Maps to:

=head2 fetch

    my $EventRoute_state   = NACL::CS::EventRoute->fetch(command_interface => $ci, ...);
	my @EventRoute_states = NACL::CS::EventRoute->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 "ems-routing-get-iter" API for CMode ZAPI.

=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.
