bfi containers

Containers such as vector, list, and set are used in the project. After running, the containers need to be cleared to release memory to reduce memory overhead. At first, I used the clear () function to release the memory. Actually, the memory was not released. As a reminder from colleagues, clear () cannot release the memory and needs to be released using swap. So I checked and found the following informat

View STL containers in GDB (The main content of this article comes from http://sourceware.org/gdb/wiki/STLSupport) Currently, GDB cannot print the content of the STL container by default, but there are many ways to do this on the Internet. I tried it and it is easier to do the following: Table of contents 1 GDB-STL-Views 2 GDB 7.0 1 GDB-STL-Views This is a macro written by Dan Marinescu to view the content of the gdb container. I

Object-Oriented Design (OOD) helps us develop high-performance, scalable, and reusable programs. Among them, Ood has an important idea, that is, relying on the inverted principle (DIP), and extended concepts such as IOC, Di, and IOC containers. This article describes four concepts with examples and provides sample code for the Java version.Dependency inversion principle (DIP) Dependency inversion is a software architecture design principle ,. The depe

Label: Ar uses the on as object relational function C string1: The container must support two types of operations. This type can be used as the elements of the container. First, the element type supports the value assignment operation, but the element type supports the object copy operation. 2: Special requirements for operations. For example, if the container element type is class type and the class only provides single-value initialization constructor, VEC (n) operations are not allowed, the c

Introduction to Vector (T) containers and instances in Cocos2d-xVector Is Cocos2d-x 3. x releases the list container, so what it can hold is the object pointer created by Ref and subclass, where T is the template, indicating the type that can be put into the container, in the Cocos2d-x 3. in x, T indicates the Ref class. Vector It is a std: vector that imitates C ++. Template Class. In terms of memory management, the reference cou

) No corresponding method Convert to arrays No corresponding method ToArray ()ToArray (t[] T) As we can see from the table above, both containers provide the ability to add, modify, delete, and traverse the container, and for map, because its unique mapping structure provides the ability to find value based on key, while collection is a set of elements of the same type, So it provides a way to convert to ToArray.T

Docker creates mirrors based on containers that already have mirrors* Docker run Centos/bin/bash first causes the mirror to open the container.* Docker start DE8 launches the specified mirror container. De8 is the ID of the image and can be shortened to 3 bits.* After running Docker exec-it De8/bin/bash, enter into the specified container, DE8 is the ID, can be abbreviated to 3-bit. We make some changes, such as installing something, and then creating

Recently, because of the work, various things, busy to die. The user found that the software has a problem, and whether it is not their own operation of the problem, a mouthful of convinced that is a software problem, ask what question when "there is a problem" three word response is also drunk.It's never been said before. Docker saw the data volume container as if it was useful to know what the data volume container is. The most basic use of data volume con
