Functions

asDocIndexIterator

fun asDocIndexIterator(disi: IndexedDISI): KnnVectorValues.DocIndexIterator

Returns an iterator that delegates to the IndexedDISI. Advancing this iterator will advance the underlying IndexedDISI, and vice-versa.

createBlockSlice

fun createBlockSlice(slice: IndexInput, sliceDescription: String, offset: Long, length: Long, jumpTableEntryCount: Int): IndexInput

Helper method for using .IndexedDISI. Creates a disiSlice for the IndexedDISI data blocks, without the jump-table.

createJumpTable

fun createJumpTable(slice: IndexInput, offset: Long, length: Long, jumpTableEntryCount: Int): RandomAccessInput?

Helper method for using .IndexedDISI. Creates a RandomAccessInput covering only the jump-table data or null.

writeBitSet

fun writeBitSet(it: DocIdSetIterator, out: IndexOutput): Short

Writes the docIDs from it to out, in logical blocks, one for each 65536 docIDs in monotonically increasing gap-less order. DENSE blocks uses .DEFAULT_DENSE_RANK_POWER of 9 (every 512 docIDs / 8 longs). The caller must keep track of the number of jump-table entries (returned by this method) as well as the denseRankPower (9 for this method) and provide them when constructing an IndexedDISI for reading.
