=head1 NAME

Net::LDAP::Control::VLVResponse -- LDAPv3 Virtual List View server response

=head1 SYNOPSIS

See L<Net::LDAP::Control::VLV>

=head1 DESCRIPTION

C<Net::LDAP::Control::VLVResponse> is a sub-class of L<Net::LDAP::Control>.
It provides a class for manipulating the LDAP Virtual List View Response control
C<>

If the server supports Virtual List Views, then the response from a search operation will
include a VLVResponse control.

=head1 CONSTRUCTOR ARGUMENTS

In addition to the constructor arguments described in
L<Net::LDAP::Control> the following are provided.

=over 4

=item content

An estimate of the number of entries in the complete list. This value should
be used in any subsequent Virtual List View control using the same list.

=item context

An arbitrary value which is used to associate subsequent requests with the
request which this control is a response for. This value should be copied
by the client into the Virtual List View control for any subsequent
search that uses the same list.

=item result

A result code indicating the result of the Virtual List View request. This
may be any of the codes listed below.

=item target

The list offset of the target entry.

=back

=head1 METHODS

As with L<Net::LDAP::Control> each constructor argument
described above is also available as a method on the object which will
return the current value for the attribute if called without an argument,
and set a new value for the attribute if called with an argument.

=head1 RESULT CODES

Possible results from a sort request are listed below. See L<Net::LDAP::Constant> for
a definition of each.

=item LDAP_SUCCESS

=item LDAP_OPERATIONS_ERROR

=item LDAP_TIMELIMIT_EXCEEDED

=item LDAP_ADMIN_LIMIT_EXCEEDED

=item LDAP_INSUFFICIENT_ACCESS

=item LDAP_BUSY
