Overloading of functions. the signature of a function includes the name of the function and its arguments, including the type of the parameter and the keyword (out/ref), excluding the return type of the function.5. Delegation. A type that stores references as functions. The life of a delegate is similar to a function, without a f

following format:Public abstract class name{Public abstract return type method name (parameter list)}Abstract method is not a general empty method, abstract method declaration, there is no method body, only after the method followed by a semicolon.2 Overloaded abstract methodsWhen you define a derived class of an abstract class, derived classes naturally inherit abstract method members from the abstract class and must override the abstract method of the abstract class, which is different from t

startprocesslocked to start the process of application A, Before startprocesslocked, however, it is possible to start provider in the same process, without having to put provider in another process. Originally ContentProvider can provide data to different clients in different processes, but if not necessary, ContentProvider is called within the same process to save more resources. So when Getcontentproviderimpl, this judgment is the Canrunhere function in Contentproviderrecord. The following co

: Synchronizing dirty pages generated by mmapThe page recycling mechanism consists of three parts, data brush out flush, swap swap, releasing release.Data brush flush and data synchronization are similar, which is to synchronize the page cache with backup files to disk, so that these pages can be recycledSwap swap is primarily for anonymous mappings, private mappings, malloc dynamically allocated memory pages that do not have backup files, and swap them to swap areas located on disk to reclaim t

pressed element, at the top) Queue Collection processing queues: The Queue (Heap collection) is based on the FIFO principle. Queue q = new Queue (); Q.enqueue (3); Enqueue (object) Adds an object to the end of the queue. Dequeue () Removes and returns the object at the top of the queue. Peek () Returns the object at the top of the queue, but does not remove the object. The number of elements in the Count heap. HashTable: The Hashtable collection is stored in the form of a key-value pair. Has

Cases: 　　 Class Dog {public Dog (string Dogbreed,int Weight) {Weight = Weight;　　This.dogbreed = Dogbreed;　　Public Dog (String dogbreed) {this.dogbreed = Dogbreed; } string dogbreed;//the dog species int weight; Weight } The example above contains two multiple constructors that accept different parameters. This represents the Dogbreed field for the current instance (referencing the current object), the dog instance. Class member variable (field): In the example above, dogbreed,

We can refer to this way to define our own root class.Local variable storage durationThe macro indicates that the values stored in some local variables should not be forcibly freed by the compiler when optimizing.We mark local variables as ID types or pointers to OBJC object types so that the values stored in these local variables are not forced to be freed by the compiler when optimized. Instead, these values are saved before the variable is assigned another value or before the scope of the lo

Wrapping variables with quotation marksThere is an example in section 4.1 of the Advanced Bash Scripting Programming Guide:hello="a B c d"echo $hello # a B c Decho" $hello" # A B C DIt was inconceivable at the time that the second echo should be very well understood, and why would the first echo remove the whitespace from the original variable? In fact, the first echo in the $hello variable, because it contains a space and no quotation marks wrapped, in fact, for the echo command provi

The current Google Sandbox unfortunately has two levels. You only get the trust of Google to get the ranking of web pages. In fact, it is too early to consider the web page ranking, because the web page must be indexed first to have the ranking problem. Because, if most of your pages are classified as supplemental materials, you are not actually indexed!Why is the page classified as "supplemental materials? Obviously, Google indexing page files is very picky. It is said that the only site s

You can connect to your Android device with Wi-Fi via a standard TCP/IP connection.This is especially useful when developing applications that monitor USB-related events, because USB connections can interfere, such as USB connection/disconnection events.The first thing to do is to connect your Android device and computer with a USB cable as usual.Also make sure that your computer and device are connected to the same Wi-Fi.Next go to the IP address of the device, open setting->wi-fi->advanced (Se

run, while for normal threads the preemptive mode is used to quickly switch execution.(2) Thread parallel problemIn a single-core single-CPU hardware architecture, the parallel running of threads is a user's subjective experience. In fact, there may only be one thread in the running state at any one time. However, in a multi-CPU or multi-core architecture, the situation is slightly different. A multi-CPU multi-core architecture allows the system to run two or more threads with no other resource

. Figure 7-43 Superscript and subscriptThe superscript does not change the size of the element text.(8). length values and percentagesSimilar to the superscript, the length and percent values cause the baseline of the element (the bottom of the replacement element) to rise (positive) or lower (a negative value) relative to the parent element's baseline.The moving dimensions of the index are determined by the browser, and the length value or percentage can be used to precisely cont
