DESCRIPTION
The Net::LDAP::Entry object represents a single entry in the directory.
It is a container for attribute-value pairs.
A Net::LDAP::Entry object can be used in two situations. The first and
probably most common use is in the result of a search to the directory
server.
The other is where a new object is created locally and then a single
command is sent to the directory server to add, modify or replace an
entry. Entries for this purpose can also be created by reading an LDIF
file with the Net::LDAP::LDIF module.
CONSTRUCTORS
new ( )
Create a new entry object with the changetype set to 'add'.
Optionally, you can provide a DN and a list of arguments passed to
the add method.
Net::LDAP::Entry->new()
# or
Net::LDAP::Entry->new( $dn )
# or
Net::LDAP::Entry->new( $dn ,
objectClass => [qw( top posixAccount )] , uid => 'admin'
)
clone ( )
Returns a copy of the Net::LDAP::Entry object.
METHODS
add ( ATTR => VALUE, ... )
Add more attributes or values to the entry and returns the entry
itself. Each "VALUE" should be a string if only a single value is
wanted in the attribute, or a reference to an array of strings if
multiple values are wanted. The values given will be added to the
values which already exist for the given attributes.
$entry->add ( 'sn' => 'Barr' );
$entry->add ( 'street' => [ '1 some road','nowhere' ] );
NOTE: these changes are local to the client and will not appear on
the directory server until the "update" method is called. As "add"
returns the entry, you can write something like.
$entry->add ( 'sn' => 'Barr' )->update( $ldap );
attributes ( OPTIONS )
Return a list of attributes in this entry
nooptions => 1
Return a list of the attribute names excluding any options. For
example for the entry
name: Graham Barr
name;en-us: Bob
jpeg;binary: **binary data**
then
@values = $entry->attributes;
print "default: @values\n";
@values = $entry->attributes ( nooptions => 1 );
print "nooptions: @values\n";
will output
default: name name;en-us jpeg;binary
nooptions: name jpeg
changetype ( )
Returns the type of operation that would be performed when the
update method is called.
changetype ( TYPE )
Set the type of operation that will be performed when the update
method is called to "TYPE". Returns the entry itself.
Possible values for "TYPE" are
add The update method will call the add method on the client
object, which will result in the entry being added to the
directory server.
delete
The update method will call the delete method on the client
object, which will result in the entry being removed from the
directory server.
$entry->delete->update( $ldap )
modify
The update method will call the modify method on the client
object, which will result in any changes that have been made
locally being made to the entry on the directory server.
moddn/modrdn
The update method will call the moddn method on the client
object, which will result in any DN changes that have been made
locally being made to the entry on the directory server. These
DN changes are specified by setting the entry attributes
newrdn, deleteoldrdn, and (optionally) newsuperior.
delete ( )
Delete the entry from the server on the next call to "update".
delete ( ATTR => [ VALUE, ... ], ... )
Delete the values of given attributes from the entry. Values are
references to arrays; passing a reference to an empty array is the
same as passing "undef", and will result in the entire attribute
being deleted. For example:
$entry->delete ( 'mail' => [ 'foo.bar@example.com' ] );
$entry->delete ( 'description' => [ ], 'streetAddress' => [ ] );
NOTE: these changes are local to the client and will not appear on
the directory server until the "update" method is called.
dn ( )
Get the DN of the entry.
dn ( DN )
Set the DN for the entry, and return the previous value.
NOTE: these changes are local to the client and will not appear on
the directory server until the "update" method is called.
ldif ( OPTION => VALUE, ... )
Returns the entry as an LDIF string. Possible options are
change => VALUE
If given a true value then the LDIF will be generated as a
change record. If false, then the LDIF generated will
represent the entry content. If unspecified then it will
default to true if the entry has changes and false if no
changes have been applied to the entry.
dump ( [ FILEHANDLE ] )
Dump the entry to the given filehandle.
This method is intended for debugging purposes and does not treat
binary attributes specially.
See Net::LDAP::LDIF on how to generate LDIF output.
If "FILEHANDLE" is omitted "STDOUT" is used by default.
exists ( ATTR )
Returns "TRUE" if the entry has an attribute called "ATTR".
get_value ( ATTR, OPTIONS )
Get the values for the attribute "ATTR". In a list context returns
all values for the given attribute, or the empty list if the
attribute does not exist. In a scalar context returns the first
value for the attribute or undef if the attribute does not exist.
alloptions => 1
The result will be a hash reference. The keys of the hash will
be the options and the hash value will be the values for those
attributes. For example if an entry had:
name: Graham Barr
name;en-us: Bob
Then a get for attribute "name" with alloptions set to a true
value
$ref = $entry->get_value ( 'name', alloptions => 1 );
will return a hash reference that would be like
{
'' => [ 'Graham Barr' ],
';en-us' => [ 'Bob' ]
}
If alloptions is not set or is set to false only the attribute
values for the exactly matching name are returned.
asref => 1
The result will be a reference to an array containing all the
values for the attribute, or "undef" if the attribute does not
exist.
$scalar = $entry->get_value ( 'name' );
$scalar will be the first value for the "name" attribute, or
"undef" if the entry does not contain a "name" attribute.
$ref = $entry->get_value ( 'name', asref => 1 );
$ref will be a reference to an array, which will have all the
values for the "name" attribute. If the entry does not have an
attribute called "name" then $ref will be "undef".
NOTE: In the interest of performance the array references returned
by "get_value" are references to structures held inside the entry
object. These values and thier contents should NOT be modified
directly.
replace ( ATTR => VALUE, ... )
Similar to "add", except that the values given will replace any
values that already exist for the given attributes.
NOTE: these changes are local to the client and will not appear on
the directory server until the "update" method is called.
update ( CLIENT [, OPTIONS ] )
Update the directory server with any changes that have been made
locally to the attributes of this entry. This means any calls that
have been made to add, replace or delete since the last call to
changetype or update was made.
This method can also be used to modify the DN of the entry on the
server, by specifying moddn or modrdn as the changetype, and
setting the entry attributes newrdn, deleteoldrdn, and (optionally)
newsuperior.
"CLIENT" is a "Net::LDAP" object where the update will be sent to.
"OPTIONS" may be options to the "Net::LDAP" actions on CLIENT
corresponding to the entry's changetype.
The result will be an object of type Net::LDAP::Message as returned
by the add, modify or delete method called on CLIENT.
Alternatively "CLIENT" can also be a "Net::LDAP::LDIF" object, that
must be an LDIF file opened for writing.
In this case, "OPTIONS" my be options that the method "write_entry"
of "Net::LDAP::LDIF" takes.
Here too, the result is an object class "Net::LDAP::Message". On
error, the error code is "LDAP_OTHER" with the LDIF error message
in the error text.
