C++ (Cpp) createPositionErrorCallback Examples

Example #1

JSValue JSGeolocation::watchPosition(ExecState* exec, const ArgList& args)
{
    // Arguments: PositionCallback, (optional)PositionErrorCallback, (optional)PositionOptions

    RefPtr<PositionCallback> positionCallback = createPositionCallback(exec, static_cast<JSDOMGlobalObject*>(exec->lexicalGlobalObject()), args.at(0));
    if (exec->hadException())
        return jsUndefined();
    ASSERT(positionCallback);

    RefPtr<PositionErrorCallback> positionErrorCallback = createPositionErrorCallback(exec, static_cast<JSDOMGlobalObject*>(exec->lexicalGlobalObject()), args.at(1));
    if (exec->hadException())
        return jsUndefined();

    RefPtr<PositionOptions> positionOptions = createPositionOptions(exec, args.at(2));
    if (exec->hadException())
        return jsUndefined();
    ASSERT(positionOptions);

    int watchID = m_impl->watchPosition(positionCallback.release(), positionErrorCallback.release(), positionOptions.release());
    return jsNumber(exec, watchID);
}
