process

public void process(KEY key,
                    W window,
                    InternalWindowFunction.InternalWindowContext context,
                    Iterable<IN> input,
                    org.apache.flink.util.Collector<OUT> out)
             throws Exception

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<Iterable<IN>,OUT,KEY,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)
           throws Exception

从接口复制的说明: InternalWindowFunction

Deletes any state in the Context when the Window expires (the watermark passes its maxTimestamp + allowedLateness).

指定者:

clear 在接口中 InternalWindowFunction<Iterable<IN>,OUT,KEY,W extends Window>

context - The context to which the window is being evaluated

抛出:

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

getRuntimeContext
