void	append_missing (Varinfo info)
	Append a missing value according to info.

void	flush ()

Data Fields
std::string &	out
	Output buffer to which we append encoded data.

uint8_t	pbyte
	Byte to which we are appending bits to encode.

Detailed Description

Binary buffer with bit-level append operations.

Constructor & Destructor Documentation

wreport::buffers::BufrOutput::BufrOutput ( std::string & out )

Wrap a string into a BufrOutput.

Parameters

out	String to append data to

void wreport::buffers::BufrOutput::add_bits	(	uint32_t	val,
		int	n
	)

Append n bits from 'val'.

n must be <= 32.
