When an object in PINMemoryCache is replaced, willRemove and didRemove blocks aren't called

[davehakim]

When an object in PINMemoryCache is replaced, the willRemoveObjectBlock and the didRemoveObjectBlock for the old object aren't called.

They are called in most other cases when an object is removed via a call to removeObjectAndExecuteBlocksForKey. This happens in

removeObjectForKey

And when trimming in

trimMemoryToDate trimToCostLimit trimToCostLimitByDate

But they aren't called in ALL other cases. They are not called in the case of removing ALL objects. In that case willRemoveAllObjectsBlock and didRemoveAllObjectsBlock blocks are called instead.

Also worth noting, if trimToDate is given a date of distantPast (should this be distantFuture ?) it will call removeAll instead of the normal trim hence also skipping calls to the willRemove/didRemove blocks

Anyways, with that background in mind, should the blocks be called in the case when an object is replaced ?

And what about when an object in the cache is replaced with an object it is .equal() to ?
