Class LLRPConnector

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

public class LLRPConnector
extends LLRPConnection

LLRPConnector implements a self-initiated LLRP connection. Here is a simple code example:

LLRPConnector c = new LLRPConnector(endpoint,ip);

c.connect();

// send message asynchronously - response needs to handled via

// the message received method of the endpoint

c.send(llrpmessage);

// send message synchronously

LLRPMessage m = c.transact(llrpmessage);

The connect method checks the status of the ConnectionAttemptStatus field in in the READER_EVENT_NOTIFICATION message. If the status field is not 'Success", an LLRPConnectionAttemptFailedException is thrown.

Method Detail

connect

public void connect()
             throws LLRPConnectionAttemptFailedException

connects to a LLRP device at the host address and port specified. the connect method waits by default 10 s for a response. If the READER_NOTIFICATION does not arrive or the ConnectionAttemptEventStatus is not set to 'Success', a LLRPConnectionAttemptFailedException is thrown.

Throws:

LLRPConnectionAttemptFailedException

connect

public void connect(long timeout)
             throws LLRPConnectionAttemptFailedException

connects to a LLRP device at the host address and port specified. the connect method waits for the timeperiod specified (in ms) for a response. If the READER_NOTIFICATION does not arrive or the ConnectionAttemptEventStatus is not set to 'Success', a LLRPConnectionAttemptFailedException is thrown.

Parameters:

timeout - time in ms

Throws:

LLRPConnectionAttemptFailedException

disconnect

public void disconnect()

disconnect existing connection to LLRP device.

reconnect

public boolean reconnect()

reconnect to LLRP device using host, port and handler specified.

Specified by:

reconnect in class LLRPConnection

Returns:

true if connection could be established and ConnectionAttemptEvent Status was set to 'Success', set to false otherwise

getHost

public java.lang.String getHost()

get host address of reader device.

Returns:

the host

setHost

public void setHost(java.lang.String host)

set host address of reader device.

Parameters:

host - the host to set

getPort

public int getPort()

get port on which to connect to reader device.

Returns:

the port

setPort

public void setPort(int port)

set port on which to connect to reader device.

Parameters:

port - the port to set
