is used to access each node in the tree. Each time a node is accessed, a callback mechanism (visitor mode) is used to prompt the appropriate inspector. In these callback methods, the inspector collects relevant information to determine if there is a violation of the specification.

more pronounced. The assumption is that a long method JVM may be kneeling directly. A second reason is more important:Method inlineAssuming that the JVM detects that some small methods are running frequently, it replaces the call of the method with the method body itself. Let's say the following:private int add4 (int x1, int x2, int x3, int x4) {return add2 (x1, x2) + ADD2 (x3, x4);} private int add2 (int

A second reason is more important:Method inlineIf the JVM detects a few small methods that are frequently executed, it replaces the call of the method with the method body itself. For example, the following:private int add4 (int x1, int x2, int x3, int x4) {return add2 (x1, x2) + ADD2 (x3, x4);} private int add2 (int x1, int x2) {re

The second reason is more important: Method inline If the JVM detects that some small methods are frequently executed, it replaces the method call with the method body. For example, the following: private int add4(int x1, int x2, int x3, int x4) {return add2(x1, x2) + add2(x3, x4);}private int add2(int

agile practices, the related requirements for code are either paired programming or code review. Recommended alternative code review with sonar see http://t.cn/zHFfH8a Code review efficient combination recommendation Sonarqube was recently updated on his computer to share the specific practices. This article first introduces the simplest practice: Use Jenkins to pull code without compiling and scan only. 1, first download the latest sonarqube, see th

After installing the sonar, you need to integrate with the Jenkins that the project is in, and the principle of Jenkins and sonar integration is probably this, Jenkins in its plug-in Management center, download the sonar plug-in and configure it with the sonar connection. Jenkins then notifies

And so on, it's increasingly necessary to automate devops.The real reason, of course, is that these problems were foreseen at the start of the team, so it's up to you to automate from the beginning.The tangible benefits are also obvious, savings in human costs, standardized processes, traceable release histories, free hands (repetitive labor), avoidance of errors caused by human actions, an

Sonar is not just a quality data reporting tool, but also a code quality management platform.

"The path length is n+m-2" because it can only go down or to the right (N,M)In each phase, the two paths are expanded one step at a time, and the path length is increased by 1, thus moving to the next stage.You also need to determine the current end position of the two path. and x1+y1 = x2 + y2 = i + 2So you can use three-dimensional DP maintenance, there are 4 ways to expand each time. and consider whether the two po

calculate the frequency of each sentence by counting the sentences appearing in the dataset, the number of occurrences C (x), and the total number of sentences in the dataset. X∈s,p (x) = C (x)/n indicates the frequency of X, apparently σp (x) = 1.In summary, we can find a few questions:1) The above language model only exists theoretically, when the training data set is infinitely large, the frequency of the data set can be infinitely close to the actual probability in the grammar;2) for most s

efficiency of + = and + two operator, we can see that in "+ =", the return is *this reference, and in +, the return is a temporary creation of the result, and the result object in the process of return, Because it is return by value, the compiler will drop the copy constructor to the return value and then destroy the temporary variable with result.~test (). In other words, use + + + to produce more overhead. In the case of some efficiency first, the constructor and destructor of temporary varia
