Method Detail

send

public void send(java.util.List<byte[]> tsdus,
                 java.util.List<java.lang.Integer> offsets,
                 java.util.List<java.lang.Integer> lengths)
          throws java.io.IOException

Throws:

java.io.IOException

send

public void send(byte[] tsdu,
                 int offset,
                 int length)
          throws java.io.IOException

Throws:

java.io.IOException

getMessageTimeout

public int getMessageTimeout()

setMessageTimeout

public void setMessageTimeout(int messageTimeout)

Set the TConnection timeout for waiting for the first byte of a new message. Default is 0 (unlimited)

Parameters:

messageTimeout - in milliseconds

getMessageFragmentTimeout

public int getMessageFragmentTimeout()

setMessageFragmentTimeout

public void setMessageFragmentTimeout(int messageFragmentTimeout)

Set the TConnection timeout for receiving data once the beginning of a message has been received. Default is 60000 (60 seconds)

Parameters:

messageFragmentTimeout - in milliseconds

receive

public void receive(java.nio.ByteBuffer tSduBuffer)
             throws java.io.EOFException,
                    java.net.SocketTimeoutException,
                    java.io.IOException,
                    java.util.concurrent.TimeoutException

Listens for a new TPDU and writes the extracted TSDU into the passed buffer.

Parameters:

tSduBuffer - the buffer that is filled with the received TSDU data.

Throws:

java.io.EOFException - if a Disconnect Request (DR) was received or the socket was simply closed

java.net.SocketTimeoutException - if a messageFragmentTimeout is thrown by the socket while receiving the remainder of a message

java.io.IOException - if an ErrorPDU (ER) was received, any syntax error in the received message header was detected or the tSduBuffer is too small to hold the complete PDU.

java.util.concurrent.TimeoutException - this exception is thrown if the first byte of new message is not received within the message timeout.

disconnect

public void disconnect()

This function sends a Disconnect Request but does not wait for a Disconnect Confirm.

close

public void close()

Will close the TCP connection if its still open and free any resources of this connection.
