.SH "DESCRIPTION"
.IX Header "DESCRIPTION"
\&\f(CW\*(C`Net::LDAP::Control::Assertion\*(C'\fR provides an interface for the creation and
manipulation of objects that represent the \f(CW\*(C`Assertion Control\*(C'\fR as described
by \s-1RFC 4528.\s0
.PP
The \f(CW\*(C`Assertion Control\*(C'\fR allows the client to specify a condition, an assertion,
that must be \s-1TRUE\s0 for the operation to be processed normally.
Otherwise, the operation is not performed.
For instance, the control can be used with the Modify operation to perform
atomic \*(L"test and set\*(R" and \*(L"test and clear\*(R" operations.
.PP
The control is appropriate for both \s-1LDAP\s0 interrogation and update operations,
including Add, Compare, Delete, Modify, ModifyDN (rename), and Search.
.SH "CONSTRUCTOR ARGUMENTS"
.IX Header "CONSTRUCTOR ARGUMENTS"
In addition to the constructor arguments described in
Net::LDAP::Control the following are provided.
.IP "assertion => \s-1FILTER\s0" 4
.IX Item "assertion => FILTER"
A filter specifying the assertion that must evaluate to \s-1TRUE\s0 in order to make the
operation process normally.
.SH "METHODS"
.IX Header "METHODS"
As with 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.
