PagedGrowableWriter

class PagedGrowableWriter : AbstractPagedMutable<PagedGrowableWriter>

A PagedGrowableWriter. This class slices data into fixed-size blocks which have independent numbers of bits per value and grow on-demand.

You should use this class instead of the PackedLongValues related ones only when you need random write-access. Otherwise this class will likely be slower and less memory-efficient.

Constructors

PagedGrowableWriter

constructor(size: Long, pageSize: Int, startBitsPerValue: Int, acceptableOverheadRatio: Float)

Create a new PagedGrowableWriter instance.

Properties

acceptableOverheadRatio

val acceptableOverheadRatio: Float

bitsPerValue

val bitsPerValue: Int

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).

val pageMask: Int

val pageShift: Int

val size: Long

val subMutables: Array<PackedInts.Mutable?>

Functions

get

open override fun get(index: Long): Long

Get value at index.

grow

@JvmOverloads

fun grow(minSize: Long = size() + 1): PagedGrowableWriter

Similar to ArrayUtil.grow.

indexInPage

fun indexInPage(index: Long): Int

lastPageSize

fun lastPageSize(size: Long): Int

pageIndex

fun pageIndex(index: Long): Int

pageSize

fun pageSize(): Int

ramBytesUsed

open override fun ramBytesUsed(): Long

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

resize

fun resize(newSize: Long): PagedGrowableWriter

Create a new copy of size newSize based on the content of this buffer. This method is much more efficient than creating a new instance and copying values one by one.

set

fun set(index: Long, value: Long)

Set value at index.

size

fun size(): Long

The number of values.

toString

open override fun toString(): String
