  • Method Summary

    Modifier and Type
    Method
    Description
    Attachments
    getAttachments()
    Returns a mutable context that the application layer can use to store meaningful data for itself in relation to this specific SASL context object.
    Symbol
    getChosenMechanism()
    Returns the mechanism that was sent to the server to select the SASL mechanism to use for negotiations.
    String
    getHostname()
    The DNS name of the host (either fully qualified or relative) that was sent to the server which define the host the sending peer is connecting to.
    <T> T
    getLinkedResource()
     
    <T> T
    getLinkedResource(Class<T> typeClass)
    Gets the linked resource (if set) and returns it using the type information provided to cast the returned value.
    SaslContext.Role
    getRole()
    Return the Role of the context implementation.
    SaslOutcome
    getSaslOutcome()
    Provides a low level outcome value for the SASL authentication process.
    EngineSaslDriver.SaslState
    getSaslState()
    Returns a SaslState that indicates the current operating state of the SASL negotiation process or conversely if no SASL layer is configured this method should return the no-SASL state.
    Symbol[]
    getServerMechanisms()
    After the server has sent its supported mechanisms this method will return a copy of that list for review by the server event handler.

    Links a given resource to this SaslContext.

  • Method Details

    • setLinkedResource

      SaslContext setLinkedResource(Object resource)
      Links a given resource to this SaslContext.
      Parameters:
      resource - The resource to link to this SaslContext.
      Returns:
      this SaslContext instance.

    • getLinkedResource

      <T> T getLinkedResource()
      Type Parameters:
      T - The type that the linked resource should be cast to on return.
      Returns:
      the user set linked resource for this SaslContext instance.

    • getLinkedResource

      <T> T getLinkedResource(Class<T> typeClass)
      Gets the linked resource (if set) and returns it using the type information provided to cast the returned value.
      Type Parameters:
      T - The type to cast the linked resource to if one is set.
      Parameters:
      typeClass - the type's Class which is used for casting the returned value.
      Returns:
      the user set linked resource for this Context instance.
      Throws:
      ClassCastException - if the linked resource cannot be cast to the type requested.

    • getAttachments

      Attachments getAttachments()
      Returns a mutable context that the application layer can use to store meaningful data for itself in relation to this specific SASL context object.
      Returns:
      the Attachments instance that is associated with this SaslContext

    • getRole

      SaslContext.Role getRole()
      Return the Role of the context implementation.
      Returns:
      the Role of this SASL Context

    • isDone

      boolean isDone()
      Returns:
      true if SASL authentication has completed

    • isServer

      default boolean isServer()
      Returns:
      true if this is a SASL server context.

    • isClient

      default boolean isClient()
      Returns:
      true if this is a SASL client context.

    • getSaslOutcome

      SaslOutcome getSaslOutcome()
      Provides a low level outcome value for the SASL authentication process.

      If the SASL exchange is ongoing or the SASL layer was skipped because a particular engine configuration allows such behavior then this method should return null to indicate no SASL outcome is available.

      Returns:
      the SASL outcome code that results from authentication

    • getSaslState

      EngineSaslDriver.SaslState getSaslState()
      Returns a SaslState that indicates the current operating state of the SASL negotiation process or conversely if no SASL layer is configured this method should return the no-SASL state. This method must never return a null result.
      Returns:
      the current state of SASL Authentication.

    • getServerMechanisms

      Symbol[] getServerMechanisms()
      After the server has sent its supported mechanisms this method will return a copy of that list for review by the server event handler. If called before the server has sent the mechanisms list this method will return null.
      Returns:
      the mechanisms that the server offered to the client.

    • getChosenMechanism

      Symbol getChosenMechanism()
      Returns the mechanism that was sent to the server to select the SASL mechanism to use for negotiations. If called before the client has sent its chosen mechanism this method returns null.
      Returns:
      the SASL mechanism that the client selected to use for negotiation.

    • getHostname

      String getHostname()
      The DNS name of the host (either fully qualified or relative) that was sent to the server which define the host the sending peer is connecting to. If called before the client sent the host name information to the server this method returns null.
      Returns:
      the host name the client has requested to connect to.
