Constructor & Destructor Documentation

geos::OutputStreamDeviation::OutputStreamDeviation ( PosixId fileNo )

Construct and enable a new pipe redirection.

Parameters

fileNo The file descriptor number, as returned by fileno() or can be one of the following: "STDOUT_FILENO" (1), "STDERR_FILENO" (2).

void geos::OutputStreamDeviation::flush	(	LineHandlingFunctor const &	lineProcessingFunctor,
		std::string_view	detectionLocation
	)

Flush the buffer from the original output pipe in a string, allowing to log it where needed.

Parameters

lineProcessingFunctor	see LineHandlingFunctor.
detectionLocation	A label to describe when the flush() operation is being made, thus explaining to the user when the error has been detected.
