=head1 ABSTRACT

UNISPOOL type 5 device

=head1 DESCRIPTION

Class C<HH::Unispool::Config::Entry::Device::5> holds information for UNISPOOL type 5 device

=head1 CONSTRUCTOR

=over

=item new(OPT_HASH_REF)

Creates a new C<HH::Unispool::Config::Entry::Device::5> object. C<OPT_HASH_REF> is a hash reference used to pass initialization options. C<OPT_HASH_REF> is mandatory. On error an exception C<Error::Simple> is thrown.

Options for C<OPT_HASH_REF> may include:

=over

=item B<C<header_name>>

Passed to L<set_header_name()>.

=item B<C<remote_device_name>>

Passed to L<set_remote_device_name()>. Mandatory option.

=item B<C<remote_system_name>>

Passed to L<set_remote_system_name()>. Mandatory option.

=item B<C<trailer_name>>

Passed to L<set_trailer_name()>.

=back

Options for C<OPT_HASH_REF> inherited through package B<C<HH::Unispool::Config::Entry>> may include:

=over

=item B<C<name>>

Passed to L<set_name()>. Mandatory option.

=back

Options for C<OPT_HASH_REF> inherited through package B<C<HH::Unispool::Config::Entry::Device>> may include:

=over

=item B<C<description>>

Passed to L<set_description()>.

=item B<C<filter_name>>

Passed to L<set_filter_name()>. Mandatory option.

=back

Options for C<OPT_HASH_REF> inherited through package B<C<HH::Unispool::Config::Entry::Numbered>> may include:

=over

=item B<C<diff_number>>

Passed to L<set_diff_number()>. Defaults to B<0>.

=item B<C<number>>

Passed to L<set_number()>.

=back

=item new_from_tokenizer(TOKENIZER)

This method is an implementation from package C<HH::Unispool::Config::Entry::Device>. Constructs a new C<HH::Unispool::Config::Entry> object using tokens. C<TOKENIZER> is an C<HH::Unispool::Config::File::Tokenizer> reference. On error an exception C<Error::Simple> is thrown.

=back

=head1 METHODS

=over

=item diff(TO [, DIFF_NUMBER])

This method is an implementation from package C<HH::Unispool::Config::Entry::Device>. Finds differences between two objects. In C<diff> terms, the object is the B<from> object and the specified C<TO> parameter the B<to> object. C<TO> is a reference to an identical object class. Returns an empty string if no difference found and a difference descritpion string otherwise. On error an exception C<Error::Simple> is thrown. Paremeter C<DIFF_NUMBER> if specified, overrules the value of C<get_diff_number>.

=item get_description()

This method is inherited from package C<HH::Unispool::Config::Entry::Device>. Returns the description for the device.

=item get_filter_name()

This method is inherited from package C<HH::Unispool::Config::Entry::Device>. Returns the name of the filter file to be used when printfiles for this device are generated.

=item get_header_name()

Returns the control procedure to be executed before printing the printfile.

=item get_name()

This method is inherited from package C<HH::Unispool::Config::Entry>. Returns the entry name.

=item get_number()

This method is inherited from package C<HH::Unispool::Config::Entry::Numbered>. Returns the entry number.

=item get_remote_device_name()

Returns the device on the remote system that will receive the output.

=item get_remote_system_name()

Returns the name of the system to which the output for this device must be routed.

=item get_trailer_name()

Returns the control procedure to be executed after printing the printfile.

=item is_diff_number()

This method is inherited from package C<HH::Unispool::Config::Entry::Numbered>. Returns whether L<diff()> should consider the C<number> attribtutes or not.

=item set_description(VALUE)

This method is inherited from package C<HH::Unispool::Config::Entry::Device>. Set the description for the device. C<VALUE> is the value. On error an exception C<Error::Simple> is thrown.

=item ^.*$

=back

=back

=item set_name(VALUE)

=over

=item VALUE must match regular expression:

=over

=item ^.+$

=back

=back

=item set_number(VALUE)

This method is inherited from package C<HH::Unispool::Config::Entry::Numbered>. Set the entry number. C<VALUE> is the value. On error an exception C<Error::Simple> is thrown.
