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

org.objectweb.asm.MethodVisitor.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. Thisopcode is 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}).

                    Class[] signature = new Class[] { RubyKernel.IRUBY_OBJECT };
                    Class ret = getReturnClass(method, signature);
                    ClassWriter cw = createCtorFast(mnamePath);
                    MethodVisitor mv = startCallSFast(cw);


                    mv.visitMethodInsn(INVOKESTATIC, typePath, method, sig(ret, signature));
                    mv.visitInsn(ARETURN);
                    mv.visitMaxs(1, 3);
                    c = endCall(cw, mv, mname);
                }
                FastInvocationCallback ic = (FastInvocationCallback) c.newInstance();
