Constructor & Destructor Documentation

template<typename BasicJsonType , typename CharType >

nlohmann::detail::binary_writer< BasicJsonType, CharType >::binary_writer ( output_adapter_t< CharType >  adapter )

inlineexplicit

create a binary writer

Parameters

[in]

adapter

output adapter to write to

Member Function Documentation

template<typename BasicJsonType , typename CharType >

char nlohmann::detail::binary_writer< BasicJsonType, CharType >::ubjson_prefix ( const BasicJsonType &  j ) const

inlineprivatenoexcept

determine the type prefix of container values

Note

This function does not need to be 100% accurate when it comes to integer limits. In case a number exceeds the limits of int64_t, this will be detected by a later call to function write_number_with_ubjson_prefix. Therefore, we return 'L' for any value that does not fit the previous limits.
