Looking for the right pattern.

[Ken]

Hi,

I’m looking for an OO pattern that synchronizes two arrays, something like
an event. Thus when the first array deletes an element the second would
also needs to delete the same element.

Thanks in advance.

hi,
from what i understand of your requirement . you need to use the observer
pattern as described in the GOF book. this pattern takes care of any changes
in the publisher and notifies all the subscribers of this change.

i hope this helps.

Thanks for you help.
I was looking up the Command pattern as a possibility.
