Conflict filter components implement the atg.service.filter.ItemFilter interface. The targeting servlet beans call this interface’s filterItems method, passing in the targeter’s result set plus the same name resolver that was passed to the targeter:

public Object[] filterItems(Object[] pItems, NameResolver pResolver)

In addition, conflict filter components implement the atg.service.filter.ItemHistory interface. The targeting servlet beans call this interface’s recordItems method, passing in the result of the filterItems method to keep the history of all displayed items for further conflict resolutions:

public void recordItems(Object[] pItems);
