AbstractIterator

abstract class AbstractIterator(size: Int, docs: PagedMutable, delGen: Long) : DocValuesFieldUpdates.Iterator

Constructors

constructor(size: Int, docs: PagedMutable, delGen: Long)

Functions

open override fun advance(target: Int): Int

Advances to the first beyond the current whose document number is greater than or equal to target, and returns the document number itself. Exhausts the iterator and returns .NO_MORE_DOCS if target is greater than the highest document number in the set.

advanceExact

open override fun advanceExact(target: Int): Boolean

Advance the iterator to exactly target and return whether target has a value. target must be greater than or equal to the current .docID and must be a valid doc ID, ie. 0 and <maxDoc. After this method returns, .docID returns target.

binaryValue

abstract fun binaryValue(): BytesRef

Returns a binary value for the current document if this iterator is a binary value iterator.

cost

open override fun cost(): Long

Returns the estimated cost of this DocIdSetIterator.

delGen

open override fun delGen(): Long

Returns delGen for this packet.

docID

open override fun docID(): Int

Returns the following:

hasValue

open override fun hasValue(): Boolean

Returns true if this doc has a value

intoBitSet

open fun intoBitSet(upTo: Int, bitSet: FixedBitSet, offset: Int)

Load doc IDs into a FixedBitSet. This should behave exactly as if implemented as below, which is the default implementation:

longValue

abstract fun longValue(): Long

Returns a long value for the current document if this iterator is a long iterator.

nextDoc

open override fun nextDoc(): Int

Advances to the next document in the set and returns the doc it is currently on, or .NO_MORE_DOCS if there are no more docs in the set.

NOTE: after the iterator has exhausted you should not call this method, as it may result in unpredicted behavior.
