Types

type ObjectPool

type ObjectPool[T any] struct {
	// contains filtered or unexported fields
}

ObjectPool 基于 sync.Pool 实现的线程安全的对象池

• 一些高频临时生成使用的对象可以通过 ObjectPool 进行管理，例如属性计算等

func NewObjectPool

func NewObjectPool[T any](generator func() *T, releaser func(data *T)) *ObjectPool[*T]

NewObjectPool 创建一个 ObjectPool

Example

package main

import (
	"fmt"
	"github.com/kercylan98/minotaur/utils/collection"
	"github.com/kercylan98/minotaur/utils/hub"
)

func main() {
	var p = hub.NewObjectPool[map[int]int](func() *map[int]int {
		return &map[int]int{}
	}, func(data *map[int]int) {
		collection.ClearMap(*data)
	})

	m := *p.Get()
	m[1] = 1
	p.Release(&m)
	fmt.Println(m)
}

Output:

map[]

func (*ObjectPool[T]) Get

func (op *ObjectPool[T]) Get() T

Get 获取一个对象

func (*ObjectPool[T]) Release

func (op *ObjectPool[T]) Release(data T)

Release 将使用完成的对象放回缓冲区
