C++ (Cpp) MutableHandleValue::isInt32示例

示例#1

void JS_FASTCALL
stubs::ToId(VMFrame &f)
{
    Value &objval = f.regs.sp[-2];
    MutableHandleValue idval = MutableHandleValue::fromMarkedLocation(&f.regs.sp[-1]);

        THROW();

    if (!idval.isInt32())
        TypeScript::MonitorUnknown(f.cx, f.script(), f.pc());
