从接口复制的说明: InternalWindowFunction

Evaluates the window and outputs none or several elements.

指定者:

process 在接口中 InternalWindowFunction<IN,OUT,Byte,W extends Window>

context - The context in which the window is being evaluated.

input - The elements in the window being evaluated.

out - A collector for emitting elements.

抛出:

Exception - The function may throw exceptions to fail the program and trigger recovery.

clear

public void clear(W window,
                  InternalWindowFunction.InternalWindowContext context)
