Examples of org.apache.mahout.cf.taste.common.Refreshable.refresh()

org.apache.mahout.cf.taste.common.Refreshable.refresh()

Triggers "refresh" -- whatever that means -- of the implementation. The general contract is that any {@link Refreshable} should always leave itself in a consistent, operational state, and thatthe refresh atomically updates internal state from old to new.

@param alreadyRefreshed {@link org.apache.mahout.cf.taste.common.Refreshable}s that are known to have already been refreshed as a result of an initial call to a {@link #refresh(Collection)} method on someobject. This ensure that objects in a refresh dependency graph aren't refreshed twice needlessly.
