get_ubjson_string()

template<typename BasicJsonType , typename InputAdapterType , typename SAX = json_sax_dom_parser<BasicJsonType>>

bool nlohmann::detail::binary_reader< BasicJsonType, InputAdapterType, SAX >::get_ubjson_string ( string_t &  result, const bool  get_char = true  )

inlineprivate

reads a UBJSON string

This function is either called after reading the 'S' byte explicitly indicating a string, or in case of an object key where the 'S' byte can be left out.

Parameters

[out]	result	created string
[in]	get_char	whether a new character should be retrieved from the input (true, default) or whether the last read character should be considered instead

Returns

whether string creation completed
