    • getClientSocket

      public java.net.Socket getClientSocket()
      Sockets are used in the operating system as channels of communication between two processes.

      Socket

    • getInput

      public java.io.BufferedReader getInput()
      Stream used to read from the client.

    • getOutput

      public java.io.Writer getOutput()
      Stream used to write to the client.

    • getReadyToStop

      public boolean getReadyToStop()
      Indicates if the thread is ready to stop. Set to true when closing of the connection is initiated.

    • getSavedInfo

      public java.util.HashMap getSavedInfo()
      Map to save information about the client such as its login ID. The initial size of the map is small since it is not expected that concrete servers will want to store many different types of information about each client. Used by the setInfo and getInfo methods.

    • delete

      public void delete()

    • sendToClient

      public void sendToClient​(java.lang.String msg) throws java.io.IOException
      INSTANCE METHODS ************************************************* Sends an object to the client. This method can be overriden, but if so it should still perform the general function of sending to client, by calling the super.sendToClient() method perhaps after some kind of filtering is done.
      Parameters:
      msg - the message to be sent.
      Throws:
      java.io.IOException - if an I/O error occur when sending the

    • toString

      public java.lang.String toString()
      Returns a string representation of the client.
      Overrides:
      toString in class java.lang.Thread
      Returns:
      the client's description.

    • setInfo

      public void setInfo​(java.lang.String infoType, java.lang.Object info)
      Saves arbitrary information about this client. Designed to be used by concrete subclasses of AbstractServer. Based on a hash map.
      Parameters:
      infoType - identifies the type of information
      info - the information itself.

    • getInfo

      public java.lang.Object getInfo​(java.lang.String infoType)
      Returns information about the client saved using setInfo. Based on a hash map.
      Parameters:
      infoType - identifies the type of information
