Package com.yahoo.prelude.query

Class SimpleIndexedItem

java.lang.Object

com.yahoo.prelude.query.Item

com.yahoo.prelude.query.SimpleTaggableItem

com.yahoo.prelude.query.SimpleIndexedItem

All Implemented Interfaces:

HasIndexItem, IndexedItem, TaggableItem, java.lang.Cloneable

Direct Known Subclasses:

TermItem

public abstract class SimpleIndexedItem
extends SimpleTaggableItem
implements IndexedItem

Common implementation for Item classes implementing the IndexedItem interface. Note that this file exist in 3 copies that should be kept in sync: CompositeIndexedItem.java SimpleIndexedItem.java IndexedSegmentItem.java These should only have trivial differences. (multiple inheritance or mixins would have been nice).
