Detailed Description

Message segmenter that keeps each packet as-is.

Member Function Documentation

◆ clear()

void DirectHubTrivialSegmenter::clear ( )

inlineoverridevirtual

Resets internal state machine.

The next call to segment_message() assumes no previous data present.

Implements MessageSegmenter.

◆ segment_message()

ssize_t DirectHubTrivialSegmenter::segment_message	(	const void *	data,
		size_t	size
	)

inlineoverridevirtual

Makes a segmenting decision given more input data.

This function will be called by the input routine repeatedly with the additional payload (non-overlapping) until the function returns a non-zero response.

That response tells how many bytes long the last packet was, which must be <= the sum of the size arguments passed in. Thereafter the read flow will call clear() and call segment_message() again with the remaining partial buffer.

Parameters

data	beginning of the buffer pointing to the next unsegmented data array.
size	how many bytes of data are available at this address. Must be >0.

Returns: 0 if no complete packet was yet seen; positive value N if the packet that starts in the first segment_message call is N bytes long. Negative return are reserved (shall not be returned at this point).

Implements MessageSegmenter.
