.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 \s-1LDAP\s0 operation that the entry
has undergone.
It is one of the following values (which represent the \s-1LDAP\s0
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 \s-1DN\s0
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 \s-1LDAP\s0
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.
