IntBlockPool

class IntBlockPool @JvmOverloads constructor(allocator: IntBlockPool.Allocator = DirectAllocator())

A pool for int blocks similar to ByteBlockPool

Constructors

constructor(allocator: IntBlockPool.Allocator = DirectAllocator())

Types

abstract class Allocator

Abstract class for allocating and freeing int blocks.

object Companion

DirectAllocator

class DirectAllocator : IntBlockPool.Allocator

A simple Allocator that never recycles.

Properties

var buffer: IntArray

Current head buffer

var buffers: Array<IntArray>

array of buffers currently used in the pool. Buffers are allocated if needed don't modify this outside of this class

var intOffset: Int

Current head offset

var intUpto: Int

Pointer to the current position in head buffer

Functions

fun nextBuffer()

Advances the pool to its next buffer. This method should be called once after the constructor to initialize the pool. In contrast to the constructor a IntBlockPool.reset call will advance the pool to its first buffer immediately.

fun reset(zeroFillBuffers: Boolean, reuseFirst: Boolean)

Expert: Resets the pool to its initial state, while optionally reusing the first buffer. Buffers that are not reused are reclaimed by . Buffers can be filled with zeros before recycling them. This is useful if a slice pool works on top of this int pool and relies on the buffers being filled with zeros to find the non-zero end of slices.
