get_binary()

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

template<typename NumberType >

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

inlineprivate

create a byte array by reading bytes from the input

Template Parameters

NumberType

the type of the number

Parameters

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

Returns

whether byte array 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 memory.
