15  * This class uses the class de.uka.ipd.coverage.utils.ByteCodePrinter to
16  * print human-readable bytecode to a reader, one instruction per line.
17  * The reader can be fetched from a
18  * ByteCodePrinterThread object after instanciating and before starting the
19  * thread via the getReader() method.<br>
20  * See ByteCodePrinter.printByteCode() for an example usage of
21  * this class.

25  * This method using a thread is somewhat cumbersome, but necessary since
26  * it uses PipedInputStream and PipedOutputStream and it is recommended
27  * to use the different Streams in different threads.
