PACKED

Compact format, all bits are written contiguously.

Properties

val id: Int

Returns the ID of the format.

expect val name: String

expect val ordinal: Int

open fun byteCount(packedIntsVersion: Int, valueCount: Int, bitsPerValue: Int): Long

Computes how many byte blocks are needed to store values values of size bitsPerValue.

open fun isSupported(bitsPerValue: Int): Boolean

Tests whether the provided number of bits per value is supported by the format.

open fun longCount(packedIntsVersion: Int, valueCount: Int, bitsPerValue: Int): Int

Computes how many long blocks are needed to store values values of size bitsPerValue.

open fun overheadPerValue(bitsPerValue: Int): Float

Returns the overhead per value, in bits.

fun overheadRatio(bitsPerValue: Int): Float

Returns the overhead ratio (overhead per value / bits per value).
