=head1 NAME

NACL::CS::DFM::Datasource

=head1 DESCRIPTION

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

=head1 ATTRIBUTES

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

=head2 fetch

    my $state = NACL::CS::DFM::Datasource->fetch(command_interface => $ci, ...);
    my @states = NACL::CS::DFM::Datasource->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.
