.SH DESCRIPTION
.IX Header "DESCRIPTION"
\&\f(CW\*(C`Net::LDAP::Control::EntryChange\*(C'\fR provides an interface for the creation
and manipulation of objects that represent the \f(CW\*(C`EntryChangeNotification\*(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 changeType 4
.IX Item "changeType"
An integer value telling the type of LDAP operation that the entry
has undergone.
It is one 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
.RE
.IP previousDN 4
.IX Item "previousDN"
.PD
When changeType is 8 (for modDN) this parameter tells the entry's DN
before the modDN operation.
In all other cases this value is not defined.
.IP changeNumber 4
.IX Item "changeNumber"
This is the change number according to <draft\-good\-ldap\-changelog\-03.txt>
assigned by a server for the change.  If a server supports an LDAP
Change Log it should include this field.
.PP
Usually you do not need to create a \f(CW\*(C`Net::LDAP::Control::EntryChange\*(C'\fR
control yourself because it is provided by the server in response to
an option with the \f(CW\*(C`Net::LDAP::Control::PersistentSearch\*(C'\fR control.
.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.
