CollectSink

public CollectSink(InetAddress hostIp,
                   int port,
                   org.apache.flink.api.common.typeutils.TypeSerializer<IN> serializer)

Creates a CollectSink that will send the data to the specified host.

参数:

hostIp - IP address of the Socket server.

port - Port of the Socket server.

serializer - A serializer for the data.

方法详细资料

invoke

public void invoke(IN value,
                   SinkFunction.Context context)
            throws Exception

从接口复制的说明: SinkFunction

Writes the given value to the sink. This function is called for every record.

You have to override this method when implementing a SinkFunction, this is a default method for backward compatibility with the old-style method only.

参数:

value - The input record.

context - Additional context about the input record.

抛出:

Exception - This method may throw exceptions. Throwing an exception will cause the operation to fail and may trigger recovery.

open

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

Initialize the connection with the Socket in the server.

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

参数:

parameters - Configuration.

抛出:

Exception

close

public void close()
           throws Exception

Closes the connection with the Socket server.

指定者:

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

覆盖:

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

抛出:

Exception
