getDoubles()

static std::optional<std::vector<double> > CesiumUtility::JsonHelpers::getDoubles ( const rapidjson::Value &  json, int32_t  expectedSize, const std::string &  key  )

static

Obtains an array of numbers from the given JSON.

If the property is not found, or is not an array, or does contain elements that are not numbers, then std::nullopt is returned.

If the given expected size is not negative, and the actual size of the array does not match the expected size, then nullopt is returned.

Parameters

json	The JSON object.
expectedSize	The expected size of the array.
key	The key (property name) of the array.

Returns

The array, or nullopt.
