在过去的java语法中,类可以被自由的继承。在新的语法中,可以用sealed密封一个类,然后使用permits限制可以继承这个类的子类 - JDK15引入了隐藏类,同时废弃了非标准的sun.misc.Unsafe::defineAnonymousClass使用Lookup::defineHiddenClass,目标是为框架提供在运行时生成内部的class - 删除 N

The Java 2D API provides several classes that define common geometric objects such as points, lines, curves, and rectangles. These geometry classes are part of thejava.awt.geompackage. ThePathIteratorinterface defines methods for retrieving elements from a path. TheShapeinterface provides a set of ...
act_procdef_*:'procdef’表示 processdefine,此前缀的表为记录流程定义信息。 act_re_*:'re’表示 repository,此前缀的表包含了流程定义和流程静态资源(图片,规则等等)。 act_ru_*:'ru’表示 runtime,此前缀的表是记录运行时的数据,包含流程实例,任务,变量,异步任务等运行中的数据。Activiti只在流程实例执行过...

第三阶段:调用preload()方法装载系统资源,包括系统预加载类、Framework资源和openGL的资源。这样当程序被fork处理后,应用的进程内已经包含了这些系统资源,大大节省了应用的启动时间。 第四阶段:调用startSystemServer()方法启动SystemServer进程 第五阶段:调动runSelectLooper方法进入监听和接收消息的循环 ...
