aScopeInDestruction - The scope in destruction. Never null.

start

@Nonnull
public EChange start()

Starts monitoring the files

Returns:

EChange

Throws:

IllegalStateException - if the monitoring is already running

stop

@Nonnull
public EChange stop()

Stops monitoring the files.

Returns:

EChange

isRunning

public boolean isRunning()

Returns:

true if the monitoring thread is running, false if not.

getDelay

public long getDelay()
