Uses of TermsEnum in org.apache.lucene.index

Subclasses of TermsEnum in org.apache.lucene.index

Modifier and Type	Class	Description
class	AutomatonTermsEnum	A FilteredTermsEnum that enumerates terms based upon what is accepted by a DFA.
class	BaseTermsEnum	A base TermsEnum that adds default implementations for BaseTermsEnum.attributes() BaseTermsEnum.termState() BaseTermsEnum.seekExact(BytesRef) BaseTermsEnum.seekExact(BytesRef, TermState) In some cases, the default implementation may be slow and consume huge memory, so subclass SHOULD have its own implementation if possible.
