Class RealDataTest

java.lang.Object

org.jlab.coda.emu.test.RealDataTest

public class RealDataTest
extends java.lang.Object

This class is designed to find the bottleneck in using real Hall D data in simulated ROC. It's a hacked-up version of RocSimulation and DataChannelImplEmu.

Method Detail

main

public static void main(java.lang.String[] args)

Run as a stand-alone application.

Parameters:

args - args

run

public void run()

This method is executed as a thread.

writeToBuffer

public void writeToBuffer()

createCodaTag

public static int createCodaTag(boolean sync,
                                boolean error,
                                boolean isBigEndian,
                                boolean singleEventMode,
                                int id)

setupOutputRingBuffer

void setupOutputRingBuffer()

Setup the output channel ring buffer.

eventToOutputRing

void eventToOutputRing(java.nio.ByteBuffer buf,
                       ByteBufferItem item,
                       ByteBufferSupply bbSupply)

This method places many ROC Raw events with simulated data onto the ring buffer of an output channel.

Parameters:

buf - the event to place on output channel ring buffer

item - item corresponding to the buffer allowing buffer to be reused

bbSupply - ByteBuffer supplier.

writeEventBuffer

void writeEventBuffer(java.nio.ByteBuffer buf,
                      java.nio.ByteBuffer templateBuf,
                      long eventNumber,
                      long timestamp,
                      boolean syncBit,
                      boolean copy,
                      int generatedDataBytes)
