Method Process

api.go:96–96

Process processes a single Record, and then optionally sends it to next filter in the chain. Process might mutate the Record, adding/modifying/removing fields, and might decide to throw it away, or pass it to next filter in chain by calling the next() function. In some cases, a filter might generate

(l Record, next func(Record))

	// it points to a function that wraps up the filtering chain and sends
	// the Record to the output.
	Process(l Record, next func(Record))

	// Stats returns stats about the filter
	Stats() FilterStats
