public class ChunkField

extends HibernateObject

A block of data that is retrieved and cached together. The boundaries of a IChunk are defined according to QueryParameters. Data items may have attributes such as category, date, name, etc. Some of these, for example category and date, will correspond to QueryParameters. A IChunk is a grouping of data items in the same part of the QueryParameter space. How this space is divided is determined by a ISemanticCache.
