GrowableWriter

class GrowableWriter(startBitsPerValue: Int, valueCount: Int, acceptableOverheadRatio: Float) : PackedInts.Mutable

Implements PackedInts.Mutable, but grows the bit count of the underlying packed ints on-demand.

Beware that this class will accept to set negative values but in order to do this, it will grow the number of bits per value to 64.

Properties

bitsPerValue

open override 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).

mutable

var mutable: PackedInts.Mutable

Functions

clear

open override fun clear()

Sets all values to 0.

fill

open override fun fill(fromIndex: Int, toIndex: Int, val: Long)

Fill the mutable from fromIndex (inclusive) to toIndex (exclusive) with val.

get

open override fun get(index: Int): Long

Get the long at the given index. Behavior is undefined for out-of-range indices.

open override fun get(index: Int, arr: LongArray, off: Int, len: Int): Int

Bulk get: read at least one and at most len longs starting from index * into arr[off:off+len] and return the actual number of values that have been read.

ramBytesUsed

open override fun ramBytesUsed(): Long

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

resize

fun resize(newSize: Int): GrowableWriter

set

open override fun set(index: Int, value: Long)

Set the value at the given index in the array.

open override fun set(index: Int, arr: LongArray, off: Int, len: Int): Int

Bulk set: set at least one and at most len longs starting at off in arr into this mutable, starting at index. Returns the actual number of values that have been set.

size

open override fun size(): Int
