UE4源码剖析：MallocBinned（上）
近期着手UE4项目开发，源码源码对UnrealEngine已久仰慕，输入终于得此机会深入探索。箱体箱体鉴于项目内存性能问题，密码密码北风网crm源码决定从内存分配器着手，源码源码深入研读UE4源码。输入虽个人水平有限，箱体箱体尚不能全面理解，密码密码但愿借此机会揭开源码神秘面纱，源码源码让新手朋友们不再感到陌生。输入快虎app源码
UE4内存分配器位于硬件抽象层HAL（Hardware Abstraction Layer）中。箱体箱体具体装箱内存分配器代码位于VS项目目录：UE4/Source/Runtime/Core/Private/HAL/MallocBinned。密码密码
分析从ApplePlatformMemory::BaseAllocator开始，源码源码可发现Mac平台的默认分配器为MallocBinned，iOS的默认分配器为MallocAnsi。以下将重点分析MallocBinned。
一、确定对齐方式
FScopeLock用于局部线程锁，确保线程同步。关于Alignment的确定，通常使用默认值。37页游源码默认值取决于内存对齐方式，此处默认对齐为8字节。
二、确定有足够空间来内存对齐
代码中，SpareBytesCount用于确认空间足够。若分配内存小于8字节，则按Alignment大小匹配箱体；若大于8字节，则按Size + Alignment - sizeof(FFreeMem)匹配箱体。
三、确定箱体大小
根据Size的大小，有三种不同的电视端影视源码处理方式。k以下的内存分配采用装箱分配，PoolTable中包含个不同大小的池子。
四、初始化内存池
分析内存池初始化过程，主要工作包括：确定内存大小，分配内存块，设置内存池基本信息。
五、内存装箱
AllocateBlockFromPool从内存池中分配一个Block，实现内存装箱过程。
箱顶箱底主图指标公式源码
箱顶箱底主图指标公式源码通常用于技术分析，广告任务PHP源码以判断股价或其他金融产品价格的高低位。但请注意，具体的公式源码可能因不同的分析软件或平台而异。一般来说，箱线图（Box Plot）的构成包括箱体、箱顶、箱底、上须和下须，但主图指标公式通常指的是如何在图表上绘制这些元素。然而，标准的箱线图并不直接提供“箱顶箱底主图指标”的公式源码，因为这通常是根据具体的数据集和分析需求定制的。
1. 箱线图基本概念：
箱线图是一种用作显示一组数据分散情况资料的统计图。因形状如箱子而得名。它主要包括以下几个数据节点：箱体（一组数据的上下四分位数，Q3和Q1）、箱线（即“须”，通常是从箱体延伸出去，表示了数据的总体散布，一般是到距离箱体1.5倍IQR（内四分位距）的位置）、箱顶和箱底（即上边缘和下边缘，有时也直接由最大值和最小值表示）。
2. 主图指标与公式源码：
在金融分析软件中，主图指标通常指的是能够在主价格图表上直接显示的指标，如移动平均线、布林带等。这些指标的计算公式会被编写成源码，以便软件能够自动计算和绘制。对于箱顶和箱底，如果要在主图上显示，可能需要自定义指标或者寻找已经编写好的脚本或插件。
3. 自定义箱顶箱底指标：
若要在主图上显示箱顶和箱底，分析师可能需要编写一个自定义指标。这个指标的源码将基于箱线图的统计原理，计算给定时间周期内的数据四分位数，并将这些值绘制在主图上。这样的指标对于识别价格异常波动或潜在反转点可能非常有用。
4. 实际应用与限制：
在实际应用中，将箱线图的概念应用于金融时间序列数据可以帮助分析师更好地理解价格的分布和波动。然而，由于金融数据的连续性和动态性，直接应用传统的箱线图方法可能存在一定的局限性。因此，在编写和使用箱顶箱底主图指标时，分析师需要根据市场特性和个人经验进行适当的调整和优化。
综上所述，虽然没有一个标准的“箱顶箱底主图指标公式源码”，但通过分析箱线图的基本原理和金融数据的特点，分析师可以自定义适合自己分析需求的指标，并在金融分析软件中实现它。
