public void run()

Specified by:

run in interface java.lang.Runnable

Overrides:

init

void init(java.nio.file.Path fastDir,
          java.nio.file.Path dir)
   throws java.io.IOException

Throws:

java.io.IOException

pollNext

java.nio.file.Path pollNext()

doDelete

boolean doDelete(java.nio.file.Path dir)

wrapExecutionListener

private void wrapExecutionListener()

If this has not been done already, we wrap the ExecutionListener inside a proxy which simply delegates call to the previous listener. When the session ends, it will also call sessionEnd(). There's no clean API to do that properly as this is a very unusual use case for a plugin to outlive its main execution.

doSessionEnd

void doSessionEnd()
