=head1 NAME

NACL::CS::LunMappingShowInitiator

=head1 DESCRIPTION

C<NACL::CS::LunMappingShowInitiator> is a derived class of
L<NACL::CS::ComponentState::ONTAP|lib-NACL-CS-ComponentState-ONTAP-pm>. Object(s) of this type
are returned when NACL::C::LunMapping->show_initiator() is invoked.

((This module does not represent the state of any element, but is an object
repesentation of the output obtained when NACL::C::LunMapping->show_initiator() is invoked.)

=head1 ATTRIBUTES

The fields of the output are fields of the ComponentState object.

=over

=item C<< vserver >>

Vserver Name

Filled in for CMode CLI/ZAPI

=item C<< reporting_nodes >>

Reporting Nodes
(Array)
Note that for array fields, the accessor method can be invoked in either
scalar or list context.

my $reporting_nodes = $obj->reporting_nodes();

# $reporting_nodes contains a reference to the array of values

my @reporting_nodes = $obj->reporting_nodes();

# @reporting_nodes contains the array of values

If this field needs to be passed to the filter hash,
the value for this field should be passed in as an arrayref

# filter => { reporting_nodes = [ value1, value2...] }

=head2 fetch

    my $LunMappingShowInitiator_state  = NACL::CS::LunMappingShowInitiator->fetch(command_interface => $ci, ...);
    my @LunMappingShowInitiator_states = NACL::CS::LunMappingShowInitiator->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.

Uses CMode CLI/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.
