BytesRefBlockPool

Represents a logical list of ByteRef backed by a ByteBlockPool. It uses up to two bytes to record the length of the BytesRef followed by the actual bytes. They can be read using the start position returned when they are appended.

The BytesRef is written so it never crosses the ByteBlockPool.BYTE_BLOCK_SIZE boundary. The limit of the largest BytesRef is therefore -2 bytes.

Properties

childResources

open val childResources: MutableCollection<Accountable>

Returns nested resources of this class. The result should be a point-in-time snapshot (to avoid race conditions).

Functions

addBytesRef

fun addBytesRef(bytes: BytesRef): Int

Add a term returning the start position on the underlying ByteBlockPool. THis can be used to read back the value using .fillBytesRef.

equals

fun equals(start: Int, b: BytesRef): Boolean

Computes the equality between the BytesRef at the start position with the provided BytesRef. This is equivalent of doing:

fillBytesRef

fun fillBytesRef(term: BytesRef, start: Int)

Populates the given BytesRef with the term starting at start.

hash

fun hash(start: Int): Int

Computes the hash of the BytesRef at the given start. This is equivalent of doing:

ramBytesUsed

open override fun ramBytesUsed(): Long

Return the memory usage of this object in bytes. Negative values are illegal.

reset

fun reset()

Reset this buffer to the empty state.
