org.apache.lucene.util.BytesRefIterator

- Packages that use BytesRefIterator
  Package | Description

- - ### Uses of BytesRefIterator in org.apache.lucene.index

    Classes in org.apache.lucene.index that implement BytesRefIterator
    Modifier and Type | Class and 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.
    `static class` | `ExitableDirectoryReader.ExitableTermsEnum` Wrapper class for TermsEnum that is used by ExitableTerms for implementing an exitable enumeration of terms.
    `class` | `FilteredTermsEnum` Abstract class for enumerating a subset of all terms.
    `static class` | `FilterLeafReader.FilterTermsEnum` Base class for filtering `TermsEnum` implementations.
    `class` | `MultiTermsEnum` Exposes `TermsEnum` API, merged from `TermsEnum` API of sub-segments.
    `static class` | `PrefixCodedTerms.TermIterator` An iterator over the list of terms stored in a `PrefixCodedTerms`.
    `class` | `SingleTermsEnum` Subclass of FilteredTermsEnum for enumerating a single term.
    `class` | `TermsEnum` Iterator to seek (`TermsEnum.seekCeil(BytesRef)`, `TermsEnum.seekExact(BytesRef)`) or step through (`next()` terms to obtain frequency information (`TermsEnum.docFreq()`), `PostingsEnum` or `PostingsEnum` for the current term (`TermsEnum.postings(org.apache.lucene.index.PostingsEnum)`.

  - ### Uses of BytesRefIterator in org.apache.lucene.search

    Classes in org.apache.lucene.search that implement BytesRefIterator
    Modifier and Type | Class and Description
    --- | ---
    `class` | `FuzzyTermsEnum` Subclass of TermsEnum for enumerating all terms that are similar to the specified filter term.
    `static class` | `PointInSetQuery.Stream` Iterator of encoded point values.

  - ### Uses of BytesRefIterator in org.apache.lucene.util

    Classes in org.apache.lucene.util that implement BytesRefIterator
    Modifier and Type | Class and Description
    --- | ---
    `static class` | `OfflineSorter.ByteSequencesReader` Utility class to read length-prefixed byte[] entries from an input.

    Fields in org.apache.lucene.util declared as BytesRefIterator
    Modifier and Type | Field and Description
    --- | ---
    `static BytesRefIterator` | BytesRefIterator.`EMPTY` Singleton BytesRefIterator that iterates over 0 BytesRefs.

    Methods in org.apache.lucene.util that return BytesRefIterator
    Modifier and Type | Method and Description
    --- | ---
    `BytesRefIterator` | BytesRefArray.`iterator()` sugar for `BytesRefArray.iterator(Comparator)` with a `null` comparator
    `BytesRefIterator` | BytesRefArray.`iterator(Comparator<BytesRef> comp)` Returns a `BytesRefIterator` with point in time semantics.
