Class LLRPAcceptor

java.lang.Object
  org.llrp.ltk.net.LLRPConnection
      org.llrp.ltk.net.LLRPAcceptor

public class LLRPAcceptor
extends LLRPConnection

LLRPAcceptor implements a remotely initiated LLRP connection. Here is a simple code example:

LLRPAcceptor c = new LLRPAcceptor(endpoint);

c.bind();

// wait for incoming reader initiated connection .....

// send message asynchronously

c.send(llrpmessage);

// asynchronously LLRP messages arrive via LLRPEndpoint.messageReceived

// send message synchronously

LLRPMessage m = c.transact(llrpmessage);

Constructor Detail

LLRPAcceptor

public LLRPAcceptor()

LLRPAcceptor

public LLRPAcceptor(LLRPEndpoint endpoint)

creates a remotely initiated LLRP connection on default PORT 5084 and uses LLRPIoHandlerAdapterImpl by default

Parameters:

endpoint - that handles incoming, asynchronous LLRP messages

LLRPAcceptor

public LLRPAcceptor(LLRPEndpoint endpoint,
                    int port)

creates a remotely initiated LLRP connection and uses LLRPIoHandlerAdapterImpl by default

Parameters:

endpoint - that handles incoming, asynchronous LLRP messages

port - on which LLRPAcceptor is waiting for incoming connections

LLRPAcceptor

public LLRPAcceptor(LLRPEndpoint endpoint,
                    int port,
                    LLRPIoHandlerAdapter handler)

creates a remotely initiated LLRP connection and uses LLRPIoHandlerAdapterImpl by default

Parameters:

endpoint - that handles incoming, asynchronous LLRP messages

port - on which LLRPAcceptor is waiting for incoming connections

handler - which handles incoming LLRP messages

LLRPAcceptor

public LLRPAcceptor(LLRPEndpoint endpoint,
                    LLRPIoHandlerAdapter handler)

creates a remotely initiated LLRP connection on default PORT 5084

Parameters:

endpoint - that handles incoming, asynchronous LLRP messages

handler - which handles incoming LLRP messages

Method Detail

bind

public void bind()
          throws LLRPConnectionAttemptFailedException

binds the LLRPIOHandler registered to the port specified. It does not wait for an incoming READER_NOTIFICATION message with a successful ConnectionAttemptEvent. Use the bind method where you can specify a timeout instead.

Throws:

LLRPConnectionAttemptFailedException

bind

public void bind(long timeout)
          throws LLRPConnectionAttemptFailedException

binds the LLRPIOHandler registered to the port specified. The bind method waits for an incoming READER_NOTIFICATION message with a successful ConnectionAttemptEvent for the timeout specified. If the timeout is set to zero, the bind method will not wait for an incoming READER_NOTIFICATION message.

Parameters:

timeout - time in ms

Throws:

LLRPConnectionAttemptFailedException - if ConnectionAttemptStatus 'Success' in READER_NOTIFICATION message is not received within time interval specified by timeout

close

public void close()

close acceptor socket.

reconnect

public boolean reconnect()

reconnect method. currently not implemented. always returns false.

Specified by:

reconnect in class LLRPConnection

Returns:

boolean indicating failure (false) or success (true)

getPort

public int getPort()

get host address of reader device.

Returns:

the port

setPort

public void setPort(int port)

Parameters:

port - the port to set
