public class CacheHoldingArrayList
extends java.util.ArrayList

This is an extension of the the ArrayList class, designed to be used by systems that return Lists of data, with extra data that should not be flushed out of a cache until the List is garbage collected. This is used for example in the ObjectStoreItemPathFollowingImpl, when it generates a batch. The objectstore fetches additional useful objects, and stores them in the holder of a CacheHoldingArrayList as well as a cache. The holder them prevents the extra useful objects from being flushed out of the cache until the DataTranslator has finished with the batch.
