Niall Pemberton updated JCI-55:
-------------------------------
Attachment: FilesystemAlterationObserverImplTestCase.java
commons-jci-fam-ObserverImpl-improvements.patch
If this patch is accepted then it has implications for the current
FilesystemAlterationMonitor - since a single FilesystemAlterationObserver per
root directory being observed no longer makes sense with the ability to filter.
Additionally in the IO-132 proposal I split out the basic
FilesystemAlterationObserver plumbing (i.e. adding, removing and notifying
listeners) into a separate abstract class leaving just the implementation of
the checkAndNotify() method in FilesystemAlterationObserverImpl. This
facilitates other FilesystemAlterationObserver implementations and makes the
FilesystemAlterationObserverImpl easier to read - although the current
FilesystemAlterationMonitor is hardcoded only to the
FilesystemAlterationObserverImpl.

> Proposal to factor back into fam's FilesystemAlterationObserverImpl the
> improvements proposed in IO-132:
> 1) Use a matching array technique to compare previous and current directory
> contents which minimizes object creation
> 2) Allow FileFilters to be specified to monitor only portions of the file
> system, ignoring files/directories of no interest. This is more efficient and
> reduces the amount of noise from un-wanted file/directory events
> 3) Add an option to make the observer case-insenstive for file names
