Distinguish ttl removed items from manually deleted items

[Tipwheal]

Hello, I found that there're dispose and disposeAfter options in constructor.

In my case, I want to distinguish these two behaviors:

• items deleted because of ttl settings (with ttlAutoPurge)
• items deleted manually (by calling cache.delete)
  in order to destroy something like File handles to prevent memory leaks.

When an item is manually deleted by the user, I just turn the control to the user to decide when to destroy. But when the item is evicted beaucse of max size settings or ttl settings, I need to automatically destroy them in dispose or disposeAfter hooks. And I found that in both ttl deleted case and manually deleted case, the reasons are delete. So I found it hard to implement my logics.

Is there any solution to this?
