Method Detail

build

public abstract AbstractRecursiveFileSystemWatcher build(File file)

This method must be implemented by subclasses, and should basically provide a constructor. If your subclass is "Subclass", a possible implementation is return new Subclass();

Parameters:

file - the file to watch

Returns:

a freshly build RecursiveFileSystemWatcher

created

protected final void created(Path file)

Description copied from class: AbstractFileSystemWatcher

This method is invoked whenever a new file is created.

Specified by:

created in class AbstractFileSystemWatcher

Parameters:

file - the file which has been created

createdFile

protected abstract void createdFile(Path p)

This method substitutes the created(Path).

Parameters:

p - the new file created

deleted

protected void deleted(Path file)

Description copied from class: AbstractFileSystemWatcher

This method is invoked whenever a file is deleted.

Specified by:

deleted in class AbstractFileSystemWatcher

Parameters:

file - the file which has been deleted

deletedFile

protected abstract void deletedFile(Path p)

This method substitutes the deleted(Path).

Parameters:

p - the file which has been deleted

finalizeStop

protected abstract void finalizeStop()

This method substitutes the stopService().

getThreadManager

public ThreadManager getThreadManager()

Returns:

the ThreadManager

stopService

public final void stopService()

Description copied from class: AbstractService

If called, the service must stop.

Overrides:

stopService in class AbstractFileSystemWatcher
