counter

https://www.cnblogs.com/soul-stone/p/9029480.html 基于behavioral-model的simple_route测试统计功能： 1、直接关联统计，这种方式可以工作： // this counter can work!! counter count_lpm_match { type : packets_and_bytes; direct : ipv4_lpm; } table ipv4_lpm { reads { ipv4.dstAddr : lpm; } actions { set_nhop; _drop; } size: 1024; } action set_dmac(dmac) { modify_field(ethernet.dstAddr, dmac); } // this counter can work!! counter count_pkt_fwd { type : packets_and_bytes; direct : fwd_set_dmac; } table fwd_set_dmac { reads { routing_metadata.nhop_ipv4 : exact; } actions { set_dmac; _drop; } size: 512; } 2、table方式，启动失败 #define MAX

I'm starting off with a very simple example in multithreading. I'm trying to make a threadsafe counter. I want to create two threads that increment the counter intermittently to reach 1000. Code below: public class ThreadsExample implements Runnable { static int counter = 1; // a global counter public ThreadsExample() { } static synchronized void incrementCounter() { System.out.println(Thread.currentThread().getName() + ": " + counter); counter++; } @Override public void run() { while(counter<1000){ incrementCounter(); } } public static void main(String[] args) { ThreadsExample te = new

I am using AngularJS and its ng-repeat directive to display a sequence of questions. I need to number each question starting with 1 . How do I display and increment such a counter with ng-repeat ? Here is what I have so far: <ul> <li ng-repeat="question in questions | filter: {questionTypesId: questionType, selected: true}"> <div> <span class="name"> {{ question.questionText }} </span> </div> <ul> <li ng-repeat="answer in question.answers"> <span class="name"> {{answer.selector}}. {{ answer.answerText }} </span> </li> </ul> </li> </ul> Angularjs documentation is full of examples, you just need

　　一个 Counter 是一个 dict 的子类，用于计数可哈希对象。它是一个集合，元素像字典键(key)一样存储，它们的计数存储为值。计数可以是任何整数值，包括0和负数 元素从一个 iterable 被计数或从其他的 mapping (or counter)初始化： >>> c = Counter() # a new, empty counter >>> c = Counter('gallahad') # a new counter from an iterable >>> c = Counter({'red': 4, 'blue': 2}) # a new counter from a mapping >>> c = Counter(cats=4, dogs=8) # a new counter from keyword args 　　Counter对象有一个字典接口，如果引用的键没有任何记录，就返回一个0，而不是弹出一个 KeyError 计数器对象除了字典方法以外，还提供了三个其他的方法： 1. elements ( ) 返回一个迭代器，每个元素重复计数的个数。元素顺序是任意的。如果一个元素的计数小于1， elements() 就会忽略它。 >>> c = Counter(a=4, b=2, c=0, d=-2) >>> sorted(c.elements()) ['a'

Is there any tested and usable component we can use to show "Count selector" like this? Our target is to get it working from API v7 . (Taken from DatePickerDialog) After some deep testing and using, this is a list of usable Picker widget libraries Android Wheel http://code.google.com/p/android-wheel/ Number Picker from Michael Novak https://github.com/mrn/numberpicker Date Slider (which can be easily adjusted) http://code.google.com/p/android-dateslider/ Horizontal slider widget http://blog.sephiroth.it/2012/01/28/android-wheel-widget/ Backport of Android 4.2 NumberPicker https://github.com
