Method GetCacheEntries

EXPERT: Generates an array of CacheEntry objects representing all items currently in the FieldCache.

NOTE: These CacheEntry objects maintain a strong refrence to the Cached Values. Maintaining refrences to a CacheEntry the IndexReader associated with it has garbage collected will prevent the Value itself from being garbage collected when the Cache drops the WeakRefrence.

EXPERIMENTAL API: This API is considered extremely advanced and experimental. It may be removed or altered w/o warning in future releases of Lucene.
