Class OperationPurposeRequestControl

  • All Implemented Interfaces:
    java.io.Serializable

    @NotMutable
    @ThreadSafety(level=COMPLETELY_THREADSAFE)
    public final class OperationPurposeRequestControl
    extends Control
    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.
    NOTE: This class, and other classes within the 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.

    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);

                                              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.
