public interface ClientConnectionRequest {

    
Obtains a connection within a given time. This method will block until a connection becomes available, the timeout expires, or the connection manager is shut down. Timeouts are handled with millisecond precision. If abortRequest() is called while this is blocking or before this began, an InterruptedException will be thrown. 
Params:
  • timeout –   the timeout, 0 or negative for no timeout
  • timeUnit –  the unit for the timeout, may be null only if there is no timeout
Throws:
Returns: a connection that can be used to communicate
         along the given route
