Usage

From source file:com.triage.bytecodemaster.BaseWeaverTest.java

protected String printNode(AbstractInsnNode insnNode) {
    /* Create a "printer" that renders text versions of instructions */
    Printer printer = new Textifier();
    TraceMethodVisitor methodPrinter = new TraceMethodVisitor(printer);

    /* render the instruction as a string and add it to printer's internal buffer */
    insnNode.accept(methodPrinter);/*from  w w w. j  av  a  2 s  . c  o  m*/

    /* convert printer's internal buffer to string and clear the buffer (so we can reuse it later) */
    StringWriter sw = new StringWriter();
    printer.print(new PrintWriter(sw));
    printer.getText().clear();
    return sw.toString();
