The UnboundID LDAP SDK for Java is a fast, comprehensive, and easy-to-use
Java API for communicating with LDAP directory servers and performing
related tasks like reading and writing LDIF, encoding and decoding data
using base64 and ASN.1 BER, and performing secure communication. This
package contains the Standard Edition of the LDAP SDK, which is a
complete, general-purpose library for communicating with LDAPv3 directory
servers.

/**
* This class provides an implementation of the LDAP no-op control as defined in
* draft-zeilenga-ldap-noop. This control may be included in an add, delete,
* modify, or modify DN request to indicate that the server should validate the
* request but not actually make any changes to the data. It allows the client
* to verify that the operation would likely succeed (including schema
* validation, access control checks, and other processing) without making any
* changes to the server data.
*
*
* NOTE: This class, and other classes within the
* {@code com.unboundid.ldap.sdk.unboundidds} package structure, are only
* supported for use against Ping Identity, UnboundID, and
* Nokia/Alcatel-Lucent 8661 server products. These classes provide support
* for proprietary functionality or for external specifications that are not
* considered stable or mature enough to be guaranteed to work in an
* interoperable way with other types of LDAP servers.
*
*
* Note that an operation which includes the no-op control will never have a
* {@link ResultCode#SUCCESS} result. Instead, if the operation would likely
* have completed successfully if the no-op control had not been included, then
* the server will include a response with the {@link ResultCode#NO_OPERATION}
* result. If the operation would not have been successful, then the result
* code in the response will be the appropriate result code for that failure.
* Note that if the response from the server includes the
* {@link ResultCode#NO_OPERATION} result, then the LDAP SDK will not throw an
* exception but will instead return the response in an
* {@link com.unboundid.ldap.sdk.LDAPResult} object. There is no corresponding
* response control.
*
* Note that at the time this control was written, the latest version of the
* specification may be found in draft-zeilenga-ldap-noop-11. This version of
* the document does not explicitly specify either the OID that should be used
* for the control, or the result code that should be used for the associated
* operation if all other processing is completed successfully but no changes
* are made as a result of this control. Until such time as these are defined,
* this implementation uses the OID temporarily assigned for its use by the
* OpenLDAP Foundation, which is used by at least the OpenLDAP, OpenDS, and the
* Ping Identity, UnboundID, and Nokia/Alcatel-Lucent 8661 Directory Server
* implementations.
*
* This control has an OID of 1.3.6.1.4.1.4203.1.10.2 and a criticality of true.
* It does not have a value.
*
* Example
* The following example demonstrates the process for attempting to perform a
* modify operation including the LDAP no-op control so that the change is not
* actually applied:
*
* ModifyRequest modifyRequest = new ModifyRequest("dc=example,dc=com",
* new Modification(ModificationType.REPLACE, "description",
* "new value"));
* modifyRequest.addControl(new NoOpRequestControl());
*
* try
* {
* LDAPResult result = connection.modify(modifyRequest);
* if (result.getResultCode() == ResultCode.NO_OPERATION)
* {
* // The modify would likely have succeeded.
* }
* else
* {
* // The modify would likely have failed.
* }
* }
* catch (LDAPException le)
* {
* // The modify attempt failed even with the no-op control.
* }
*
