get_string()

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

template<typename NumberType >

bool nlohmann::detail::binary_reader< BasicJsonType, InputAdapterType, SAX >::get_string ( const input_format_t  format, const NumberType  len, string_t &  result  )

inlineprivate

create a string by reading characters from the input

Template Parameters

NumberType

the type of the number

Parameters

[in]	format	the current format (for diagnostics)
[in]	len	number of characters to read
[out]	result	string created by reading len bytes

Returns

whether string creation completed

Note

We can not reserve len bytes for the result, because len may be too large. Usually, unexpect_eof() detects the end of the input before we run out of string memory.
