let(block: (T) -> R): R = block(this)let函数默认当前这个对象作为闭包的it参数,返回值是函数里面最后一行,或者指定return。上面的代码还可以用?.let语句进行,如下所示:/* * 通过let语句,在?.let之后,如果为空不会有任何操作,只有在非空的时候才会执行let之后的操作 * */ user?.let { it.name it...

These methods return the public exponent e and the CRT information integers: the prime factor p of the modulus n, the prime factor q of n, the exponent d mod (p-1), the exponent d mod (q-1), and the Chinese Remainder Theorem coefficient (inverse of q) mod p. An RSA private key...
When requesting a block cipher in stream cipher mode (for example; AES in CFB or OFB mode), a client may optionally specify the number of bits to be processed at a time, by appending this number to the mode name as shown in the following sample transformations:Cipher c1 = Cipher....
内存使用率不断上升,甚至开始使用 SWAP 内存,同时可能出现 GC 时间飙升,线程被 Block 等现象,通过 top 命令发现 Java 进程的 RES 甚至超过了-Xmx的大小。出现这些现象时,基本可以确定是出现了堆外内存泄漏。 4.8.2 原因 JVM 的堆外内存泄漏,主要有两种的原因: ...
比如一个服务 RT 突然上涨,有 GC 耗时增大、线程 Block 增多、慢查询增多、CPU 负载高四个表象,到底哪个是诱因?如何判断 GC 有没有问题?使用 CMS 有哪些常见问题?如何判断根因是什么?如何解决或避免这些问题?阅读完本文,详细你将会对 CMS GC 的问题处理有一个系统性的认知,更能游刃有余地解决这些问题,下面...

概率分析: 使用统计概率学,结合历史问题的经验进行推断,由近到远按类型分析,如过往慢查的问题比较多,那么整个问题影响链就可能是:慢查询增多 -> GC 耗时增大 -> CPU 负载高 -> 线程 Block 增多 -> RT上涨。 实验分析: 通过故障演练等方式对问题现场进行模拟,触发其中部分条件( 一个或多个 ),观察是否会发生...
