ProcessAllWindowFunction

abstract class ProcessAllWindowFunction[IN, OUT, W <: Window] extends AbstractRichFunction

Base abstract class for functions that are evaluated over keyed (grouped) windows using a context for retrieving extra information.

IN

The type of the input value.

OUT

The type of the output value.

W

The type of the window.
