public class DictionaryBrowserSupplier extends Object implements Supplier<IndexDictionary.Browser>, Accountable
IndexDictionary.Browser
created on
the immutable IndexDictionary
.
The immutable IndexDictionary
is lazy loaded thread safely. This
lazy loading allows us to load it only when TermsEnum.seekCeil(org.apache.lucene.util.BytesRef)
or TermsEnum.seekExact(org.apache.lucene.util.BytesRef)
are called (it is not loaded for a direct
all-terms enumeration).
