Examples of org.objectweb.asm.CodeVisitor.visitMethodInsn()

org.objectweb.asm.CodeVisitor.visitMethodInsn()
Visits a method instruction. A method instruction is an instruction that invokes a method. @param opcode the opcode of the type instruction to be visited. This opcodeis either INVOKEVIRTUAL, INVOKESPECIAL, INVOKESTATIC or INVOKEINTERFACE. @param owner the internal name of the method's owner class (see {@link Type#getInternalName() getInternalName}). @param name the method's name. @param desc the method's descriptor (see {@link Type Type}).

      CodeVisitor gv =
        cv.visitMethod(ACC_PRIVATE, "_get" + name, gDesc, null, null);
      gv.visitFieldInsn(GETSTATIC,
        "java/lang/System", "err", "Ljava/io/PrintStream;");
      gv.visitLdcInsn("_get" + name + " called");
      gv.visitMethodInsn(INVOKEVIRTUAL,
        "java/io/PrintStream", "println", "(Ljava/lang/String;)V");
      gv.visitVarInsn(ALOAD, 0);
      gv.visitFieldInsn(GETFIELD, owner, name, desc);
