    • clone

      public Object clone() throws CloneNotSupportedException
      Clone this object. This method clones only those fields required when comparing two client MQCD structures to determine if they point at the same requested destination. e.g. newMQCD.equals(oldMQCD) == true Need to take a copy of the byte array data, otherwise the cloned object will reference the same byte array. Taking copies of the data means that if ones is updated, the other is untouched. This is useful when the MQCD is cloned for the negotiated channel in the RemoteConnection.
      Returns:
      a clone of the original object
      Throws:
      CloneNotSupportedException - for transport protocol types other than TCP.

    • hashCode

      public int hashCode()

      Overrides:
      hashCode in class Object
      Returns:
      a unique hashcode
      See Also:

    • equals

      public boolean equals(Object x)

This is intended specifically to determine if an existing connection is suitable for a new conversation to be multiplexed over. Certain fields - maxMsgLength, heartbeatInterval and sharingConversations - are excluded as they don't preclude multiplexing
      Overrides:
      equals in class Object
