LrJposChannel.getBytes

Low-level receive function that receives the bytes over the connection. It returns the total number of bytes read into the buffer.

public static int getBytes(byte[] bytes) throws IOException

public static int getBytes(byte[] bytes, int seconds) throws IOException

Parameters

ParameterDescription
bytesByte array that represents the buffer for the received bytes.
seconds

Seconds to wait for the response.

Return values

This function returns an integer that represents the length of the array received.

It returns -1 if there is no more data (because the end of the stream has been reached).

Example

Copy code
public void getBytesISOtest() throws Throwable{
        
        GenericPackager packager = new GenericPackager(PACKAGERCONFIGFILE);
        LrJposChannel.initChannel(LrJposChannel.ChannelType.ASCIIChannel, "localhost", 8000, packager);

        LrJposChannel.connect();
        
        LrISOMsg m = new LrISOMsg();
        m.setMTI("0100");

        m.set(47, "32432"); 

        LrJposChannel.send(m);
        
        byte[] rb = new byte[2048];
        int len = LrJposChannel.getBytes(rb, 5);

        else {
