.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\f(CW\*(C`Net::LDAP::Control::PersistentSearch\*(C'\fR provides an interface for the creation
and manipulation of objects that represent the \f(CW\*(C`PersistentSearch\*(C'\fR control as
described by draft\-smith\-psearch\-ldap\-03.txt.
.SH "CONSTRUCTOR ARGUMENTS"
.IX Header "CONSTRUCTOR ARGUMENTS"
In addition to the constructor arguments described in
Net::LDAP::Control the following are provided.
.IP changeTypes 4
.IX Item "changeTypes"
An integer value determining the types of changes to look out for.
It is the bitwise OR of the following values (which represent the LDAP
operations indicated next to them):
.RS 4
.IP "1 = add" 4
.IX Item "1 = add"
.PD 0
.IP "2 = delete" 4
.IX Item "2 = delete"
.IP "4 = modify" 4
.IX Item "4 = modify"
.IP "8 = modDN" 4
.IX Item "8 = modDN"
.RE
.RS 4
.PD
.Sp
If it is not given it defaults to 15 meaning all changes.
.RE
.IP changesOnly 4
.IX Item "changesOnly"
A Boolean value telling whether the server may return
entries that match the search criteria.
.Sp
If \f(CW\*(C`TRUE\*(C'\fR the server must not return any existing
entries that match the search criteria.  Entries are only
returned when they are changed (added, modified, deleted, or
subject to a modifyDN operation)
.IP returnECs 4
.IX Item "returnECs"
If \f(CW\*(C`TRUE\*(C'\fR, the server must return an Entry Change Notification
control with each entry returned as the result of changes.
.Sp
See Net::LDAP::Control::EntryChange for details.
.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.
