Description
Class Summary | |
---|---|
BlockTermsReader | Handles a terms dict, but decouples all details of
doc/freqs/positions reading to an instance of PostingsReaderBase . |
BlockTermState | Holds all state required for PostingsReaderBase
to produce a DocsEnum without re-seeking the
terms dict. |
BlockTermsWriter | Writes terms dict, block-encoding (column stride) each term's metadata for each set of terms between two index terms. |
BlockTreeTermsReader | A block-based terms index and dictionary that assigns terms to variable length blocks according to how they share prefixes. |
BlockTreeTermsReader.Stats | BlockTree statistics for a single field
returned by BlockTreeTermsReader.FieldReader.computeStats() . |
BlockTreeTermsWriter | block-based terms index and dictionary writer. |
Codec | Encodes/decodes an inverted index segment. |
CodecUtil | Utility class for reading and writing versioned headers. |
DocValuesArraySource | DocValues DocValues.Source implementation backed by
simple arrays. |
DocValuesConsumer | Abstract API that consumes IndexableField s. |
DocValuesFormat | Encodes/decodes DocValues |
FieldInfosFormat | Encodes/decodes FieldInfos |
FieldInfosReader | Codec API for reading FieldInfos . |
FieldInfosWriter | Codec API for writing FieldInfos . |
FieldsConsumer | Abstract API that consumes terms, doc, freq, prox, offset and payloads postings. |
FieldsProducer | Abstract API that produces terms, doc, freq, prox and payloads postings. |
FixedGapTermsIndexReader | TermsIndexReader for simple every-nth terms indexes. |
FixedGapTermsIndexWriter | Selects every Nth term as and index term, and hold term bytes (mostly) fully expanded in memory. |
LiveDocsFormat | Format for live/deleted documents |
MappingMultiDocsAndPositionsEnum | Exposes flex API, merged from flex API of sub-segments, remapping docIDs (this is used for segment merging). |
MappingMultiDocsEnum | Exposes flex API, merged from flex API of sub-segments, remapping docIDs (this is used for segment merging). |
MultiLevelSkipListReader | This abstract class reads skip lists with multiple levels. |
MultiLevelSkipListWriter | This abstract class writes skip lists with multiple levels. |
NormsFormat | format for normalization factors |
PerDocConsumer | Abstract API that consumes per document values. |
PerDocProducer | Abstract API that provides access to one or more per-document storage features. |
PerDocProducerBase | Abstract base class for PerDocProducer implementations |
PostingsBaseFormat | Provides a PostingsReaderBase and PostingsWriterBase . |
PostingsConsumer | Abstract API that consumes postings for an individual term. |
PostingsFormat | Encodes/decodes terms, postings, and proximity data. |
PostingsReaderBase | The core terms dictionaries (BlockTermsReader,
BlockTreeTermsReader) interact with a single instance
of this class to manage creation of DocsEnum and
DocsAndPositionsEnum instances. |
PostingsWriterBase | Extension of PostingsConsumer to support pluggable term dictionaries. |
SegmentInfoFormat | Expert: Controls the format of the
SegmentInfo (segment metadata file). |
SegmentInfoReader | Specifies an API for classes that can read SegmentInfo information. |
SegmentInfoWriter | Specifies an API for classes that can write out SegmentInfo data. |
StoredFieldsFormat | Controls the format of stored fields |
StoredFieldsReader | Codec API for reading stored fields:
You need to implement StoredFieldsReader.visitDocument(int, StoredFieldVisitor) to
read the stored fields for a document, implement StoredFieldsReader.clone() (creating
clones of any IndexInputs used, etc), and Closeable.close() |
StoredFieldsWriter | Codec API for writing stored fields: |
TermsConsumer | Abstract API that consumes terms for an individual field. |
TermsIndexReaderBase | BlockTermsReader interacts with an instance of this class
to manage its terms index. |
TermsIndexReaderBase.FieldIndexEnum | Similar to TermsEnum, except, the only "metadata" it reports for a given indexed term is the long fileOffset into the main terms dictionary file: |
TermsIndexWriterBase | Base class for terms index implementations to plug
into BlockTermsWriter . |
TermStats | Holder for per-term statistics. |
TermVectorsFormat | Controls the format of term vectors |
TermVectorsReader | Codec API for reading term vectors: |
TermVectorsWriter | Codec API for writing term vectors: |
VariableGapTermsIndexReader | See VariableGapTermsIndexWriter |
VariableGapTermsIndexWriter | Selects index terms according to provided pluggable
VariableGapTermsIndexWriter.IndexTermSelector , and stores them in a prefix trie that's
loaded entirely in RAM stored as an FST. |
VariableGapTermsIndexWriter.EveryNOrDocFreqTermSelector | Sets an index term when docFreq >= docFreqThresh, or every interval terms. |
VariableGapTermsIndexWriter.EveryNTermSelector | Same policy as FixedGapTermsIndexWriter |
VariableGapTermsIndexWriter.IndexTermSelector | Hook for selecting which terms should be placed in the terms index. |
Codecs API: API for customization of the encoding and structure of the index.
