这里有必要解释下代码(9),当日志队列满时put方法会调用await()方法阻塞当前线 程,而如果其他线程中断了该线程,那么该线程会抛出InterruptedException异常,并且当 前的日志任务就会被丢弃。在logback-classic的1.2.3版本中,则添加了不对中断进行响应 的方法。 privatevoidput(E eventObject) {if(neverBlock) { blocking...
And like the instruments of a single telescope, each of these combiners will be optimized for a particular kind of observation or scientific program. In this paper we describe the CLASSIC and CLIMB beam combiners of the CHARA Array. Both are open air, aperture plane, wide bandwidth single ...
arrayMoveImmutable(array, fromIndex, toIndex) Clones the givenarray, moves the item to a new position in the new array, and then returns the new array. The givenarrayis not mutated. arrayMoveMutable(array, fromIndex, toIndex) Moves the item to the new position in thearrayarray. Useful for...
<%' Imagine we want to load this JSON array for parsing:jsonArrayStr ="[{""id"":200},{""id"":196}]"' First wrap it in a JSON object by prepending "{ "array":" and appending "}"' For versions of Chilkat < 10.0.0, use CreateObject("Chilkat_9_5_0.StringBuilder")setsbJson =...
ArrayBlockingQueue的原理就是使用一个可重入锁和这个锁生成的两个条件对象进行并发控制(classic two-condition algorithm)。ArrayBlockingQueue是一个带有长度的阻塞队列,初始化的时候必须要指定队列长度,且指定长度之后不允许进行修改。 /**Main lock guarding all access*/finalReentrantLock lock;/**Condition for waiti...
使用[array enumerateObjectsUsingBlock:]方法迭代数组中的对象,并使用[block removeObjectForKey:]方法来删除其中的对象。例如,如果要将index=2的对象从数组中删除,可以这样定义一个方法: 代码语言:swift 复制 [array enumerateObjectsUsingBlock:^(id obj,NSUIntegeridx,BOOL*stop){if(idx==2){[array remo...
定义:联接算法是Mysql数据库用于处理联接的物理策略,目前MySQL只支持nest loop join算法,而MySQL的分支版本MariaDB除了支持nested-loops Join 还支持 Classic Hash Join算法。 根据B+树的特性,其联接的时间复杂度为 O(N),若没有索引,则视为最坏的情况,时间复杂度为 O(N*N) 。
