By combining the NTSTATUS into a single 32-bit numbering space, the following NTSTATUS values are defined. Most values also have a defined default message that can be used to map the value to a human-readable text message. When this is done, the NTST…

Python’s handling of default parameter values is one of a few things that tends to trip up most new Python programmers (but usually only once). What causes the confusion is the behaviour you get when you use a “mutable” object as a default value; tha…

数据库的在上一篇博客中<SQLite之C语言接口规范(三)——Binding Values To Prepared Statements>用到了如何从查询结果中取出结果值.今天的博客就详细的介绍一下sqlite3_column_*()的方法.在SQLite数据库C语言接口中,从查询结果中取出不同类型的值需要不同的接口函数. 一. sqlite3_column_*()介绍 1.下图是sqlite3_column_*()所包含的方法,由下图容易的看出取出不同类型的值需要不同的接口函数.可以取出的类…

android项目新建时会有一个values目录(高版本会增加values-v11,values-v14目录),该目录用于存放显示相的配置数据的定义文件,如strings.xml, style.xml, dimens.xml, arrays.xml, ids.xml等. 通常在android应用开发时,需要对多语言支持,一般是中英繁.也就是说当android系统切换到英文环境时,UI上客户端的相关操作字符显示也应显示相应的英文内容,这就需要对values目录进行扩展,具体扩展就是增加支持语言对应…

我在看HashMap源码的时候发现了一个没思考过的问题,在这之前可以说是完全没有思考过这个问题,在一开始对这个点有疑问的时候也没有想到居然有这么个语法细节存在,弄得我百思不得其解,直到自己动手做实验改写了代码才完全明白. HashMap里面保存的数据最底层是一个Entry型的数组,这个Entry则保留了一个键值对,还有一个指向下一个Entry的指针.所以HashMap是一种结合了数组和链表的结构.正因为如此,你有3种对数据的观测方式:keySet,values,entrySet.第一个是体现从k…

对于任何语言来说,函数都是一个重要的组成部分.在ES6以前,从JavaScript被创建以来,函数一直没有大的改动,留下了一堆的问题和很微妙的行为,导致在JavaScript中使用函数时很容易出现错误并且可能需要多余的代码实现一些基本的函数行为.在ES6中,函数有一个质的飞跃的改进,它充分考虑到过去数年间JavaScript开发者的需求和抱怨.与ES5相比,在ES6中使用函数开发不容易出错,而且更加灵活. 带默认参数的函数(Functions with Default Parameter Val…
