memorypool's Introduction

MemoryPool

an implement of a memorypool

一个简单而又强大的内存池实现 1个头文件+1个cpp实现

语法采用c++

#QuickMemoryPool

  • @brief : QuickMemoryPool
  • 一种简单高效的模板定长内存池实现
  • 采用预分配大块内存机制，减少malloc,free等系统call开销
  • 时间复杂度:分配内存O(1),释放内存O(1)
  • 该内存池实现参考Box2D的内存池实现，用模板参数取代了固定长度,并做了一些细节方面的优化
  • 支持任意类型对象(POD,含虚函数的等)，支持构造函数，含参构造函数， 自动触发析构函数
  • 为了保持实现的简洁和高效性，该内存池仅仅提供两个接口，申请到的指针需要用户自己做管理
  • 简单测试下，其速度相比不使用内存池的申请释放，速度达到近3倍
  • 内存池结构图 内存池有多个Chunk组成， Chunk0 ,Chunk1, Chunk2,....每个Chunk结构相同

单个Chunk结构由多个block组成,Block里存放着用户数据 Chunk:[Block0,Block1,....
