      public class EPPResponse
      extends java.lang.Object
      implements EPPMessage

  Represents an EPP response that is send by an EPP Server and received by an EPP Client. An `EPPResponse` can be encoded and decoded by `EPPCodec`. Every EPP response contain the following:
  - transaction id - Mirror of the transaction id set in the associated `EPPCommand`
  - results - One or more `EPPResult` instances.
  `EPPResponse` is a concrete class that can be extended by the Command Mapping responses. A Command Mapping response must override the Template Design Pattern `doEncode` and `doDecode` methods. `EPPResponse` provides a default `doEncode` and `doDecode` implementation that does nothing. An `EPPResponse` client will call `encode` or `decode`, which in turn will call `doEncode` or `doDecode`, respectively.

    - #### hasMessageQueue

          @Deprecated
          public boolean hasMessageQueue()

      Deprecated.
      As of EPP 1.0, replaced with `hasMsgQueue()`. This method will return `true` if a message queue object exists that has a non-`null` message count.
      Does the response have a message queue object? If so, the response message queue object can be retrieved with a call to `getMessageQueue`.
      Returns:
        `true` if this is an message queue object; `false` otherwise.

    - #### getMessageQueue

          @Deprecated
          public java.lang.Long getMessageQueue()

      Deprecated.
      As of EPP 1.0, replaced with `getMsgQueueCount()`
      Gets the response message queue object. Currently the message queue object is a `Long` count of the number of messages.
      Returns:
        Number of queue messages if defined; `null` otherwise.

    - #### getQDate

          @Deprecated
          public java.util.Date getQDate()

      Get the response message queue date.
      Returns:
        message queue date if defined; `null` otherwise.

    - #### hasMsgQueue

          public boolean hasMsgQueue()

      Does the response have a message queue object? If so, the response message queue object can be retrieved with a call to `getMsgQueue`.
      Returns:
        `true` if this is an message queue object; `false` otherwise.
      Since:
        EPP 1.0

    - #### getMsgQueue

          public EPPMsgQueue getMsgQueue()

    - #### getMsgQueueCount

          public java.lang.Long getMsgQueueCount()

      Convenience method for getting the message queue count attribute. This is equivalent to getting the message queue object by `getMsgQueue()` and than calling `EPPMsgQueue.getCount()` .

        EPP 1.0

    - #### getMsgQueueMsg

          public java.lang.String getMsgQueueMsg()

      Convenience method for getting the message queue message attribute.

      Specified by:
        `encode` in interface `EPPCodecComponent`
      Parameters:
        `aDocument` - Used as a document factory
      Returns:
