转自: 土法炼钢:怎么实现一个简单的B+Tree In-Disk1. 写在前面说起B+树,大家应该都很熟悉。B+树是一种平衡的多路搜索树,广泛在操作系统和数据库系统用作索引。相比于内存的存取速度,磁盘I/O存取的开销要高上…
This is implementation of Bayer Trees, sometime referred to as Balanced Tree and normally used for indices of data bases. These routines provide all stuff that is needed to create and destroy; insert, update and delete; load and destroy; search and traverse; check a tree.Sort huge amounts ...

B-tree implementation in C. Contribute to tidwall/btree.c development by creating an account on GitHub.
The B* tree balances more neighboring internal nodes to keep the internal nodes more densely packed.2 This variant ensures non-root nodes are at least 2/3 full instead of 1/2.13 As the most costly part of operation of inserting the node in B-tree is splitting the node, B*-trees are ...
BPlusTreeMetadata.java 这个文件包含一个类,它存储有用的信息,比如树的阶和高度.可以使用this访问该类的实例.上面列出的所有类中都有元数据实例变量. Implementation Details 实现细节 应该阅读索引目录中的所有代码.许多评论包含有关必须如何实现某些功能的重要信息.例如 BPlusNode::put 指定在拆分后如何重新分配条...

ButtonAccImpl 类(也称为 Button Accessibility Implementation 类)可实现 Button 组件与屏幕读取器之间的通信。 ButtonAccImpl—类, 包 mx.accessibility ButtonAccImpl 是 AccessibilityImplementation 的子类,可以实现 Button 类的辅助功能。 ButtonAccImpl(master:mx.core:UIComponent)— 构造函数, 类 mx.accessibility...
java的集合 总体 Iterable接口 Implementing this interface allows an object to be the target of the "for-each loop" statement map接口 是一个key映射values,每个key只有一个对应的value,作为Dictionary替代。 有三种集合:keys的set,values的collection,key-values的mapping,其中这个map的顺序由迭代器定义,像TreeMa...
