C++ (Cpp) Value::isNull Examples

Example #1

File: latlngquad.hpp Project: 1SpatialGroupLtd/mapbox-gl-native

optional<std::array<LatLng, 4>> Converter<std::array<LatLng, 4>>::operator()(const mbgl::android::Value& value, Error& error) const {
    if (value.isNull() || !value.isArray()) {
        error = { "value cannot be converted to LatLng array" };
        return {};
    }

    return convert<GeoJSON>(value.toString(), error);
}

Example #2

File: android_conversion.hpp Project: Mappy/mapbox-gl-native

inline optional<Value> toValue(const mbgl::android::Value& value) {
    if (value.isNull()) {
        return {};
    } else if (value.isBool()) {
        return { value.toBool() };
    } else if (value.isString()) {
        return { value.toString() };
    } else if (value.isNumber()) {
        //Need to cast to a double here as the float is otherwise considered a bool...
        return { (double) value.toNumber() };
    } else {
        return {};
    }
}

Example #3

File: android_conversion.hpp Project: Budroid/mapbox-gl-native

inline bool isUndefined(const mbgl::android::Value& value) {
    return value.isNull();
}
