public final class ModifyRequest
extends UpdatableLDAPRequest
implements ReadOnlyModifyRequest, ProtocolOp

This class implements the processing necessary to perform an LDAPv3 modify operation, which can be used to update an entry in the directory server. A modify request contains the DN of the entry to modify, as well as one or more changes to apply to that entry. See the Modification class for more information about the types of modifications that may be processed.

A modify request can be created with a DN and set of modifications, but it can also be as a list of the lines that comprise the LDIF representation of the modification as described in RFC 2849. For example, the following code demonstrates creating a modify request from the LDIF representation of the modification:

   ModifyRequest modifyRequest = new ModifyRequest(
     "dn: dc=example,dc=com",
     "changetype: modify",
     "replace: description",
     "description: This is the new description.");
 


ModifyRequest objects are mutable and therefore can be altered and re-used for multiple requests. Note, however, that ModifyRequest objects are not threadsafe and therefore a single ModifyRequest object instance should not be used to process multiple requests at the same time.
