There are four kinds of containers for objects in AS3: Array,object,vector,dictionary; others have mentioned several comparisons of CPU memory or speed in their blogs. The performance is not much worse, but for large projects, or for projects that need to be ported to mobile devices, the optimization is compelling.
First, choose the right type according to your needs.
Array, the general language has, here is not to say, but to know that he is an ind

order: Need header file #include
Sort (Vec.begin (), Vec.end ());(default is in ascending order, that is, from small to large.
You can compare the sort comparison functions by overriding them in descending order, as follows:
To define a sort comparison function:
BOOL Comp (const int A,CONST int b)
{return
a>b;
}
When called: Sort (Vec.begin (), Vec.end (), Comp), sorted in descending order.
The above is a small set of C + + in the use of vector

Most of the time, we place data in different regions to process different data, so how do we plan the data? Obviously, we can use containers to tolerate this data, so we have involved the concept of layout cont
Ctop: a command line artifact that monitors the performance of Linux containers
Ctop is a new command line-based tool that can be used to monitor processes at the container level. By using the resource management function of the controller group (cgroup), containers provide a virtual environment at the operating system level. The tool collects data related to memory, CPU, block input and output, as well as
"TechTarget China original" container and cloud security remain the hottest two topics in the IT world. Let's discuss it in detail below. Cloud container rage is for a reason. Containers such as Docker can improve application portability and enable enterprise users to use IT resources more effectively. As a result, the container will be further developed in the business community. "The entire container technology market has exploded in the cloud," sai
the existing elements because the Copy object calls the copy constructor. For simple small objects, vectors are more efficient than list. Vector expands the capacity by twice times each time it expands, which is very efficient for small objects.The objects in the list are stored in discrete, random access to an element that needs to traverse the list. Inserting elements into the list, especially at the end of the insert, is highly efficient and requires only changing the pointer of the element.

Many students simply understand the Docker container as a lightweight virtual machine, although this simplifies the difficulty of understanding container technology but it also leads to a lot of misunderstandings. In fact, unlike virtual machine technology: All containers running on the same host share the same kernel (the host's kernel). The great value of being containerized is that all these separate

In general, a running instance of a mirror is a container, and the container provides a writable file layer.
