org.apache.jmeter.protocol.tcp.sampler.LengthPrefixedBinaryTCPClientImpl

All Implemented Interfaces:

TCPClient

public class LengthPrefixedBinaryTCPClientImpl
extends TCPClientDecorator

Implements binary length-prefixed binary data.

This is used in ISO8583 for example. Input/Output strings are passed as hex-encoded binary strings.

2-Byte or 4-Byte length prefixes are supported.

Length prefix is binary of length specified by property "tcp.length.prefix.length".

public LengthPrefixedBinaryTCPClientImpl()

Method Details

write

public void write(OutputStream os,
 String s)
           throws IOException

Parameters:

os - - OutputStream for socket

s - - String to write

Throws:

IOException - when writing fails

write

public void write(OutputStream os,
 InputStream is)
           throws IOException

Parameters:

os - - OutputStream for socket

is - - InputStream to be written to Socket

Throws:

IOException - when writing fails

read

@Deprecated
public String read(InputStream is)
            throws ReadException

Deprecated.

Parameters:

is - - InputStream for socket

Returns:

String read from socket

Throws:

ReadException - exception that can contain partial response (Response until error occurred)

read

public String read(InputStream is,
 SampleResult sampleResult)
            throws ReadException

Default implementation calls TCPClient.read(InputStream) for backward compatibility

Specified by:

read in interface TCPClient

Overrides:

read in class AbstractTCPClient

Parameters:

is - - InputStream for socket

sampleResult - SampleResult

Returns:

String read from socket

Throws:

ReadException - exception that can contain partial response

• TCPClient.read(java.io.InputStream, org.apache.jmeter.samplers.SampleResult)

getEolByte

public byte getEolByte()

Not useful, as the byte is never used.

Get the end-of-line/end-of-message byte.

Specified by:

getEolByte in interface TCPClient

Overrides:

getEolByte in class AbstractTCPClient

Returns:

Returns the eolByte.

setEolByte

public void setEolByte(int eolInt)

Set the end-of-line/end-of-message byte. If the value is out of range of a byte, then it is to be ignored.

Specified by:

setEolByte in interface TCPClient

Overrides:

setEolByte in class AbstractTCPClient

Parameters:

eolInt - The value to set
