All Implemented Interfaces:

LPR

public class LPRQueueDepthShort
extends AbstractQueueDepth
implements LPR

Concrete implementation that Queries the LPD server for its current depth passing the long code to the server. The response is provided the caller via a Writer. This is done to allow for the user to implement a writer that can be used to parse the response from the LPD server. Due to the lack of standardization for responses the only way that I could think was to provide a writer that the Socket response could be written to.

                          java.io.Writer response)

Constructor to create a query for the LPD server to respond with the current depth of the print queue.

Parameters:

serverName - the name of the server. This is passed straight to a Socket in the constructor of new Socket(servername, port) so it will take any thing that this constructor will take

queue - the queue on the LPD server that is to be queried for

response - Writer that the response from the server will be written to.
