PostingsReaderBase

abstract class PostingsReaderBase : AutoCloseable

The core terms dictionaries (BlockTermsReader, BlockTreeTermsReader) interact with a single instance of this class to manage creation of org.gnit.lucenekmp.index.PostingsEnum and org.gnit.lucenekmp.index.ImpactsEnum instances. It provides an IndexInput (termsIn) where this class may read any previously stored data that it had written in its corresponding [ ] at indexing time.

Functions

checkIntegrity

abstract fun checkIntegrity()

Checks consistency of this reader.

abstract override fun close()

decodeTerm

abstract fun decodeTerm(in: DataInput, fieldInfo: FieldInfo, state: BlockTermState, absolute: Boolean)

Actually decode metadata for next term

impacts

abstract fun impacts(fieldInfo: FieldInfo, state: BlockTermState, flags: Int): ImpactsEnum

Return a ImpactsEnum that computes impacts with scorer.

open fun impacts(fieldInfo: FieldInfo, state: BlockTermState, flags: Int, reuse: ImpactsEnum?): ImpactsEnum

Optional reuse-aware variant of impacts. Implementations may override to reuse platform objects for performance while preserving semantics.

init

abstract fun init(termsIn: IndexInput, state: SegmentReadState)

Performs any initialization, such as reading and verifying the header from the provided terms dictionary IndexInput.

newTermState

abstract fun newTermState(): BlockTermState

Return a newly created empty TermState

postings

abstract fun postings(fieldInfo: FieldInfo, state: BlockTermState, reuse: PostingsEnum?, flags: Int): PostingsEnum

Must fully consume state, since after this call that TermState may be reused.
