public final class OperationPurposeRequestControl
extends Control

NOTE: This class is part of the Commercial Edition of the UnboundID LDAP SDK for Java. It is not available for use in applications that include only the Standard Edition of the LDAP SDK, and is not supported for use in conjunction with non-UnboundID products.
This class provides a request control that can be used by the client to identify the purpose of the associated operation. It can be used in conjunction with any kind of operation, and may be used to provide information about the reason for that operation, as well as about the client application used to generate the request. This may be very useful for debugging and auditing purposes.

The criticality for this control may be either true or false. It must have a value with the following encoding:
   OperationPurposeRequest ::= SEQUENCE {
        applicationName     [0] OCTET STRING OPTIONAL,
        applicationVersion  [1] OCTET STRING OPTIONAL,
        codeLocation        [2] OCTET STRING OPTIONAL,
        requestPurpose      [3] OCTET STRING OPTIONAL
        ... }
 
At least one of the elements in the value sequence must be present.

Example

The following example demonstrates a sample authentication consisting of a search to find a user followed by a bind to verify that user's password. Both the search and bind requests will include operation purpose controls with information about the reason for the request. Note that for the sake of brevity and clarity, error handling has been omitted from this example.
 SearchRequest searchRequest = new SearchRequest("dc=example,dc=com",
      SearchScope.SUB, Filter.createEqualityFilter("uid", uidValue),
      "1.1");
 searchRequest.addControl(new OperationPurposeRequestControl(appName,
      appVersion, 0,  "Retrieve the entry for a user with a given uid"));
 Entry userEntry = connection.searchForEntry(searchRequest);

 SimpleBindRequest bindRequest = new SimpleBindRequest(userEntry.getDN(),
      password, new OperationPurposeRequestControl(appName, appVersion, 0,
      "Bind as a user to verify the provided credentials."));
 BindResult bindResult = connection.bind(bindRequest);

OperationPurposeRequestControl

public OperationPurposeRequestControl(java.lang.String applicationName,
                                      java.lang.String applicationVersion,
                                      int codeLocationFrames,
                                      java.lang.String requestPurpose)
Creates a new operation purpose request control with the provided information. It will not be critical. If the generateCodeLocation argument has a value of false, then at least one of the applicationName, applicationVersion, and requestPurpose arguments must be non-null.

Parameters:
applicationName - The name of the application generating the associated request. It may be null if this should not be included in the control.
applicationVersion - Information about the version of the application generating the associated request. It may be null if this should not be included in the control.
codeLocationFrames - Indicates that the code location should be automatically generated with a condensed stack trace for the current thread, using the specified number of stack frames. A value that is less than or equal to zero indicates an unlimited number of stack frames should be included.
requestPurpose - A string identifying the purpose of the associated request. It may be null if this should not be included in the control.

OperationPurposeRequestControl

public OperationPurposeRequestControl(boolean isCritical,
                                      java.lang.String applicationName,
                                      java.lang.String applicationVersion,
                                      java.lang.String codeLocation,
                                      java.lang.String requestPurpose)
Creates a new operation purpose request control with the provided information. At least one of the applicationName, applicationVersion, codeLocation, and requestPurpose arguments must be non-null.

Parameters:
isCritical - Indicates whether the control should be considered critical.
applicationName - The name of the application generating the associated request. It may be null if this should not be included in the control.
applicationVersion - Information about the version of the application generating the associated request. It may be null if this should not be included in the control.
codeLocation - Information about the location in the application code in which the associated request is generated (e.g., the class and/or method name, or any other useful identifier). It may be null if this should not be included in the control.
requestPurpose - A string identifying the purpose of the associated request. It may be null if this should not be included in the control.

OperationPurposeRequestControl

public OperationPurposeRequestControl(Control control)
                               throws LDAPException
Creates a new operation purpose request control which is decoded from the provided generic control.

Parameters:
control - The generic control to be decoded as an operation purpose request control.
