I. Requirements and application scenarios
Considering the increasing number of servers in my hands, sometimes it is necessary to deploy the same file on a large scale, for example, because it is convenient to use the Systemtap tool to locate the problem, you need to install the hundreds of servers in the hand kernel-debuginfo this package, the original way to use a source server, Using rsync or SCP file transfer mode can only do a point down to distr
Large file transfer between linux and large file transfer between linux and windows solutions when the server is updated and new, and when the server system is replaced, data transfer is undoubtedly very troublesome, especially for web servers, N + images, N + pages, a headache. now I want to mention... large file transfer
This article mainly introduces the address transfer and value transfer usage of javascript array and php array. The example analyzes the array usage skills of javascript and php, which has some reference value, for more information about how to transfer the address and value of a javascript array and a php array, see the example in this article.

In Java, there are two methods for passing parameters to functions: value transfer and reference transfer. Generally, the basic type is value transfer, and the reference type is reference transfer. But what happens when the value is passed?
1. Basic Type
The eight basic types (byte, short, Int, long, float, double, Cha
Value Transfer in Android and Android value transfer
First, I will celebrate my blog for a year!
As we all know, according to the mvc design pattern, data is transmitted through the model, from one activity (A) to another activity (B) if you want to pass the value, we can put the model in the intent (or not), and then get the corresponding value after B is created; otherwise, if the value is returned to A
example, I have a song titled Chenchen singing, and I copied it to my deskmate, Xu Xiaoxiao, And she I think it is really hard to hear, I deleted it right away, she deleted the song, and I still don't affect each other. Another note is that the stack stores the address pointing to the object, so the object is copied. the address in the heap is the same, but the address in the heap is different. So the address in the AB stack is different from that in the XY stack. It is like my song is put on m

Restful (Representational Status Transfer-declarative Status Transfer) architecture style. Currently, it mainly applies to the Internet (such as mobile clients ).
Hard to understand? Let's take a look at the link style:
Http://example.com/customers/1234
In this case, REST is a set of rules defining Web standards, such as HTTP and URIs.
REST key rules

C language function parameter transfer principle, function parameter transfer
There are two methods for passing parameters in C language: stack-based and register-based. This time, we will only describe the first parameter transfer method in detail. The other method is not described here.
First, let's take a look at the following simple call routine:
Int Add (int
Reverse value transfer by iOS proxy and reverse value transfer by ios proxy
In the previous blog's iOS proxy protocol, I focused on parsing the concept of the delegated proxy protocol. This article will focus on their applications in development.
Suppose we have A requirement as follows: there is A button and A label on interface. Jump from interface A to interface B, enter A string in the input box of int
About the event transfer mechanism ., Event transfer mechanism.
Each ViewGroup includes onInterceptTouchEvent () and TouchEvent ()
Each View contains: TouchEvent ()
The event starts from the ViewGroup and passes to the ViewGroup or View.
The event cannot be passed down all the time, so onInterceptTouchEvent () is used to prevent the event from being passed like the following control.
Use TouchEvent ()
The value transfer function does not change the values of two variables.
Why, because it is only necessary to change the value of a parameter in a function to call a value.
The value pointed to by the address changes not only within the function, but also outside the function.

In the passl-by-value process, the formal parameters of the called function are processed as local variables of the called function, that is, the memory space is opened in the stack to store the values of the real parameters put in by the main function, thus becoming a copy of the real parameters. The feature of value transfer is that any operation of the form parameter of the called function is performed as a local variable, without affecting the val

Value Transfer Agent for iOS and value transfer agent for ios
There are several methods for transmitting values in iOS, including: pass value by proxy, pass value by block, pass value by attribute, transfer value by notification, pass value by single case, and pass value by userdefault or file, generally, value passing by proxy and block are the most common metho
In the traditional sense, the JavaScript function is thought to pass the reference pass (also known as the Pointer Pass), and some people think that the value transfer and the reference pass have. So JS parameter transmission in the end is how it? In fact, the following demo is also fully available for Java
