Method Detail

open

public void open()
          throws Exception

Description copied from class: AbstractStreamOperator

This method is called immediately before any elements are processed, it should contain the operator's initialization logic, e.g. state initialization.

The default implementation does nothing.

Specified by:

open in interface StreamOperator<OUT>

Overrides:

open in class AbstractStreamOperator<OUT>

Throws:

Exception - An exception in this method causes the operator to fail.

useSplittableTimers

public boolean useSplittableTimers()

Description copied from class: AbstractStreamOperator

Can be overridden to disable splittable timers for this particular operator even if config option is enabled. By default, splittable timers are disabled.

Overrides:

useSplittableTimers in class AbstractStreamOperator<OUT>

Returns:

true if splittable timers should be used (subject to StreamConfig.isUnalignedCheckpointsEnabled() and StreamConfig.isUnalignedCheckpointsSplittableTimersEnabled(). false if splittable timers should never be used.

computeMemorySize

public long computeMemorySize()

Compute memory size from memory faction.

processWatermark

public void processWatermark(Watermark mark)
                      throws Exception

Overrides:

processWatermark in class AbstractStreamOperator<OUT>

Throws:

Exception
