see the name F1, this is the name of the function, in this meaning is called the function itself, this is recursion! - F1 (Depth +1, A2, A3) This code means to call itself, depth +1, A2, A3 into the parameters of the function itself. - so the current R = F1 (depth +1, A2, A3) ===> r = F1 (2, 1, 1) the when we get the value of this variable R, I go down to see ' return R ', and return value will take the value just obtained from the R variable as the argument of the function and re-pass it into

the same content from the server again and again, creating redundancy for the user and reducing the efficiency of the app. Ideally, we send a request to get real new data. When the server's data does not change, it will get a 304 response code, and OkHttp returns the cached response. This can happen if the server supports caching. So what you need to do is to study ETag or Note: Please do not set if-modified-since or if-none-match yourself. As mentioned earlier, setting these two headers skips

After running, you can open the example to see the effect, in the Source/demos folder, it is recommended to post under Tomcat (this is relatively simple), open as localhost, because directly open some textures are local files, security permissions problems may be problematic Ok,that is all, open your first webglobe with chrome and experience it yourself, and the next section is going to introduce yo

. __NEW__ is a response to an implicit initialization requirement for an object's state, allowing an initialization to be defined at a lower level than __init__, which is always called.The __new__ () method is more like a real constructor than __init__ (). With the unification of classes and types, the user can derive from the built-in type, thus requiring a way to instantiate an immutable object, such as a derived string, in which case the interpreter invokes the __new__ () method of the class,

SummaryThreadLocal can not completely solve the multi-threaded programming concurrency problem, the problem also depends on different circumstances to choose a different solution, "Space Change Time" or "time for space."Threadlocal's biggest role

" Android:layout_weight=" 1 " Android:text=" button "/>linearlayout> The Layout_weight property is described in the development documentation as follows: Defines the maximum value of the weight sum. If this value is not specified, the cumulative value of the Layout_weight property of all child views is used as the maximum value of the sum. A typical case is: by specifying the Layout_weight property of the child view to 0.5, and setting the LinearLayout's Weightsum property to 1.0, the implem
