Class CompositeIndexedItem

java.lang.Object

com.yahoo.prelude.query.Item

com.yahoo.prelude.query.CompositeItem

com.yahoo.prelude.query.CompositeTaggableItem

com.yahoo.prelude.query.CompositeIndexedItem

All Implemented Interfaces:

HasIndexItem, IndexedItem, TaggableItem, Cloneable

Direct Known Subclasses:

PhraseItem

public abstract class CompositeIndexedItem
extends CompositeTaggableItem
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).
