OneInputStreamTask

public OneInputStreamTask(org.apache.flink.runtime.execution.Environment env)

Constructor for initialization, possibly with initial state (recovery / savepoint / etc).

参数:

env - The task environment for this task.

OneInputStreamTask

@VisibleForTesting
public OneInputStreamTask(org.apache.flink.runtime.execution.Environment env,
                                             @Nullable
                                             TimerService timeProvider)

Constructor for initialization, possibly with initial state (recovery / savepoint / etc).

This constructor accepts a special TimerService. By default (and if null is passes for the time provider) a DefaultTimerService will be used.

参数:

env - The task environment for this task.

timeProvider - Optionally, a specific time provider to use.
