Spring batch: Stop the batch job if no items are written

I am working on spring batch job. Flow is like below

step 1: (read,process,write on File1)

step 2: mail entries

step 3: (read,process,write on File2)

step 4: mail entries for File2.

I want to skip mailing step if no items are written.

I came across decision control like

<batch:decision id="decision" decider="com/Decider">
        <batch:next on="FAILED" to="step_3"/>
        <batch:next on="COMPLETED" to="step_2"/>
</batch:decision>

But how to get write count from previous step to this decision class?

JobExecutionDecider#decide has a StepExecution parameter where you can find how many items were written during last step execution (StepExecution#getWriteCount)
