Constructor Detail

### RemoteCycConnection

    public RemoteCycConnection(java.lang.String myAgentName,
                               java.lang.String remoteAgentName,
                               int remoteAgentCommunity)
                        throws java.io.IOException

  Constructs a new RemoteCycConnection object to the given CycProxyAgent in the given agent community.
  Parameters:
    `myAgentName` - the name of the local agent
    `remoteAgentName` - the name of the cyc proxy agent

Method Detail

### converse

    public java.lang.Object[] converse(java.lang.Object message)
                                throws java.io.IOException,
                                       CycApiException

  Send a message to Cyc and return the `Boolean` true as the first element of an object array, and the cyc response Symbolic Expression as the second element. If an error occurs the first element is `Boolean` false and the second element is the error message string.
  Specified by:
    `converse` in interface `CycConnectionInterface`
  Parameters:
    `message` - the api command
  Returns:
    an array of two objects, the first is an Integer response code, and the second is the response object or error string.

### converse

    public java.lang.Object[] converse(java.lang.Object message,
                                       Timer timer)
                                throws java.io.IOException,

                                       CycApiException

  Send a message to Cyc and return the response code as the first element of an object array, and the cyc response Symbolic Expression as the second element, spending no less time than the specified timer allows but throwing a `TimeOutException` at the first opportunity where that time limit is exceeded. If an error occurs the second element is the error message string.
  Specified by:
    `converse` in interface `CycConnectionInterface`
  Parameters:
    `message` - the api command which must be a String or a CycList
    `timeout` - a `Timer` object giving the time limit for the api call
