, that is, its top "customers."3. STL containers and allocator then utilize the interface of the runtime library to implement their own policies and optimizations. In addition, we can create our own memory allocator, that is, our own memory pool. You can let the STL container not use the default allocator, and use your own defined memory pool to allocate memory.Finally, if you never use a memory pool or a memory allocator and use New/delete directly to manage your own memory, this behavior also

Copy Code code as follows: 1. Hierarchy selector: Through the hierarchical relationship between DOM elements, the main hierarchical relationships include descendants, father and son, neighboring, sibling relationships, through which the base-class relationship can easily and quickly locate elements jquery Selector Detailed Depending on the elements in the obtained page, you can divide the jquery selector into: basic selector,

Basic Selector The base selector is the most commonly used selector in jquery and the simplest selector, which looks for DOM elements by element ID, class, and tag name. In a Web page, each ID name can only be used once, and class allows reuse. Selector Describe Return Example #id Matches an element based on the given ID A single element $ ("#test") select an element with the ID test . class Matches the element based on the given

Simple CSS Selector-Hierarchy Selector * CSS level selector has 4 * 1. Descendant selector: $ (' div p '), in all descendants (descendants) of the ancestor element, query the specified element * 2. Child element selector: $ (' div > P '), find in all child elements of parent element * 3. Adjacent selector: $ ('. Top + li '), select the immediate sibling adjacent element of the current element * 4. Brother selector: $ ('. Top ~ li '), select all sibli

Java class loader (1)-Class Loader hierarchy and ModelClass Loader ?? The virtual machine design team put the "get and describe the binary byte stream of this class through the full qualified name of a class" action in the class loading stage outside the Java Virtual Machine for implementation, so that the application can decide how to obtain the required classes. The Code module that implements this action is called the class loader ". Class Loader l

The previous article tested the effect of the build order on the order of execution, linking: LinkThis article mainly tests the loop order of the three common messages in Awake,onenable,start First one of the simplest print test codevoid Awake () { Debug.Log ("awake" + name); } void onenable () { Debug.Log ("onenable" + name); } void Start () { Debug.Log ("Start" + name); }Print MessageThe test results are awake and onenable in the first cycle

management such as cache, and software management such as virtual memory can also be used.3, the management of the cachei) Related assumptionsAssuming that the memory address has m-bits, there are m=2m different addresses.A cache is partitioned into s=2s cache set,Each group contains an E cache line.Each cache line consists of a b=2b byte block, a valid bit, and a t=m-(b+s) tag bit.The size of a high buffer zone C = S * E * B.II) How to access the cacheWhen you want to access a byte in memory,

I. Type of document Nodetype:9; NodeName: "#document"; Nodevalue:null; Parentvalue:null; Ownerdocumet:null. Other browsers (except IE) can access the document's constructor and prototype; All browsers (including IE8 +) access the constructors and prototypes of the HTMLDocument; var html = document.documentelement; // var body = document.body; // Second, find the element document.getElementById () | | Documet.getelementbytagname | | Documet.getelementbynamedocument.getElementById ()--case-sensit

, greatly speeding up the speed. Access to the same address takes advantage of temporal locality (time), and access to the neighboring address takes advantage of spatial locality (spatial).Cache Memory:　　What we need if it is called a cache hit in the buffer is called cache miss. When the cache is empty it is called cold cache, and we begin to access the data to give it warm up (^o^)The structure of the cache (fill in later)The address of the access cache is divided into three parts, the highest
