use Protocol::SPDY::Constants ':all';

=head2 type_name

The string type for this frame ('WINDOW_UPDATE').

=cut

sub type_name { 'WINDOW_UPDATE' }

=head2 from_data

Instantiate from the given data.

=cut

sub from_data {
	my $class = shift;
	my %args = @_;
	my ($stream_id, $window_delta) = unpack "N1N1", substr $args{data}, 0, 8, '';
	$stream_id    &= ~0x80000000;
	$window_delta &= ~0x80000000;

	$class->new(
		%args,
		stream_id    => $stream_id,
		window_delta => $window_delta,
	);
}

=head2 stream_id

Which stream we're updating the window for.

=cut

	);
}

=head2 to_string

String representation, for debugging.

=cut
