RUNNABLE(运行状态) 与 BLOCKED(阻塞状态) RUNNABLE状态的线程在进入由synchronized修饰的方法或代码块前将会尝试获取一把隐式的排他锁,一旦获取不到,线程状态将会变成BLOCKED,等待获取锁。一旦有其他线程释放这把锁,线程成功抢到该锁,线程状态就将会从BLOCKED转变为RUNNABLE状态。 RUNNABLE(运行状态) 与 WATTING(等待状...

Java 语言的 “编译期” 其实是一段 “不确定” 的操作过程,因为它可能是指一个前端编译器(其实叫 “编译器的前端” 更准确一些)把 .java文件转变成 .class文件的过程;也可能是指虚拟机的后端运行期编译器(JIT 编译器,Just In Time Compiler)把字节码转变成机器码的过程;还可能是指使用静态提前编译器(AOT ...
只有ACK标志为 1时确认序号字段才有效。发送ACK无需任何代价,因为 32 bit的确认序号字段和A C K标志一样,总是T C P首部的一部分。因此,我们看到一旦一个连接建立起来,这个字段总是被设置, ACK标志也总是被设置为1。TCP为应用层提供全双工服务。这意味数据能在两个方向上独立地进行传输。因此,连接的每一端必...
统计一个方法中循环体代码执行的次数,在字节码中遇到控制流向后跳转的指令称为"回边"(Back Edge)。目的时为了触发OSR编译 当解释器遇到一条回边指令时,会先查找将要执行的代码片段是否有已经编译好的版本,如果有,它将会优先执行已编译的代码,否则就把回边计数器的值加1,然后判断方法调用计数器与回边计数器值之...
This will be used in conjunction with 'Match index' to pick the required element. For example: If 'Sort by column name' is [TopEdge] and 'Match index' is 1 then the matching element nearest the top of the screen will be matched. Match index is ascending MatchIndexAscending boolean ...

ET模式(边缘触发)(Edge - Triggered)是高速工作方式,只支持Nonblock socket,在这种模式下,当描述符从未就绪变为就绪时,内核通过epoll检测到。然后它会假设你知道文件描述符已经就绪,并且不会再为那个文件描述符发送更多的就绪通知,直到你做了某些操作导致那个文件描述符不再为就绪状态了,但是注意,如果一直不对这个fd进...
