方法详细资料

getMaxOutputDelay

public long getMaxOutputDelay()

Get the maximum interval between receiving a row and emitting it (as part of a joined result). This is the time interval by which watermarks need to be held back.

返回:

the maximum delay for the outputs

open

public void open(org.apache.flink.configuration.Configuration parameters)
          throws Exception

指定者:

open 在接口中 org.apache.flink.api.common.functions.RichFunction

覆盖:

open 在类中 org.apache.flink.api.common.functions.AbstractRichFunction

抛出:

Exception
