ForUtil
FreqProxPostingsArray
FreqProxTermsWriter
FreqProxTermsWriterPerField
Lucene50PostingsFormat
Lucene50PostingsReader	Concrete class that reads docId(maybe frq,pos,offset,payloads) list with postings format.
Lucene50PostingIterator	`PostingIterator` impl for `Lucene50PostingsReader`
Lucene50PostingsWriter	Concrete class that writes docId(maybe frq,pos,offset,payloads) list with postings format.
Lucene50SkipReader	Implements the skip list reader for block postings format that stores positions and payloads.
Lucene50SkipWriter	Write skip lists with multiple levels, and support skip within block ints.
ParallelPostingsArray
PerFieldFieldsReader
PerFieldFieldsWriter
PerFieldPostingsFormat	Enables per field postings support.
TermsHashBase	This class is passed each token produced by the analyzer on each field during indexing, and it stores these tokens in a hash table, and allocates separate byte streams per token. Consumers of this class, eg {@link FreqProxTermsWriter} and {@link TermVectorsConsumer}, write their own byte streams under each term.
TermsHashPerFieldBase

FieldsConsumerEnum
FieldsProducerEnum	`FieldsProducer` impl for `PostingsFormatEnum`
PostingsFormatEnum	composite `PostingsFormat` use for `CodecEnum`

BLOCK_SIZE	Fixed packed block size, number of integers encoded in a single packed block.
DOC_CODEC
DOC_EXTENSION	Filename extension for document number, frequencies, and skip data. See chapter: Frequencies and Skip Data
MAX_DATA_SIZE	Upper limit of the number of values that might be decoded in a single call to {@link #read_block(IndexInput, u8, i32)}. Although values after `BLOCK_SIZE` are garbage, it is necessary to allocate value buffers whose size is `MAX_DATA_SIZE` to avoid `IndexOutOfBounds` Error.
MAX_ENCODED_SIZE	Upper limit of the number of bytes that might be required to stored `BLOCK_SIZE` encoded values.
MAX_SKIP_LEVELS	Expert: The maximum number of skip levels. Smaller values result in slightly smaller indexes, but slower skipping in big posting lists.
PAY_CODEC
PAY_EXTENSION	Filename extension for payloads and offsets. See chapter: Payloads and Offsets
PER_FIELD_POSTING_FORMAT_KEY	Name of this {@link PostingsFormat}. / {@link FieldInfo} attribute name used to store the format name for each field. /
PER_FIELD_POSTING_SUFFIX_KEY	segment suffix name for each field. */
POS_CODEC
POS_EXTENSION	Filename extension for positions. See chapter: Positions
TERMS_CODEC
VERSION_CURRENT

FieldsConsumer	Abstract API that consumes terms, doc, freq, prox, offset and payloads postings. Concrete implementations of this actually do "something" with the postings (write it into the index in a specific format).
FieldsProducer	Abstract API that produces terms, doc, freq, prox, offset and payloads postings
PostingsArray
PostingsFormat	Encodes/decodes terms, postings, and proximity data.
PostingsWriterBase
TermsHash
TermsHashPerField

lucene50_decode_term	Actually decode metadata for next term @see PostingsWriterBase#encodeTerm
max_data_size
postings_format_for_name
