Class FieldTermIterator

java.lang.Object

org.apache.lucene.index.FieldTermIterator

All Implemented Interfaces:

BytesRefIterator

Direct Known Subclasses:

PrefixCodedTerms.TermIterator

abstract class FieldTermIterator
extends java.lang.Object
implements BytesRefIterator

Iterates over terms in across multiple fields. The caller must check field() after each BytesRefIterator.next() to see if the field changed, but == can be used since the iterator implementation ensures it will use the same String instance for a given field.
