Prior to cocos2dxv3.0beta, there were sequential containers cocos2d: CCArray, and cocos2d: CCDictionary. However, after the new version, both containers will be replaced by cocos2d: VectorT and cocos2d: MAPKs and V. 1. cocos2d: VectorTcocos2d: VectorT is an ordered container that encapsulates an array of dynamic sizes.

The difference between the Set,list,map,vector,arraylist
The difference between the Set,list,map,vector,arraylist
Java Container---List,map,setCollection├list│├linkedlist│├arraylist│└
The collection and map interfaces are provided in Java. List and set inherit the collection interface, and use the vector, arraylist, and sorted List classes to implement the list interface, while hashset and treeset implement the set interface. Hashtable, hashmap, and treemap are directly used to implement the map interface.
Java Container---List,map,setCollection├list│├linkedlist│├arraylist│└vector│└stack└setMap├hashtable├hashmap└weakhashmapCollection interfaceCollection is the most basic set interface, and a collection represents a set of object, the collection element (Elements). Some collection allow the same elements while others do not. Some can be sorted and others not. The Java SDK does not provide classes that directly
1, vector map vector map is also called Vector map, is a series of computer instructions to describe and record a picture, a picture can be solved by a series of points, lines, faces wait until the composition of the child graph,
set and vector is that the set does not contain duplicate data. The difference between set and map is that the set contains only key, and map has a value of two elements corresponding to the key and key. The difference between map and Hash_map is that Hash_map uses the hash algorithm to speed up the lookup process, bu
In STL, the basic containers include string, vector, list, deque, set, and map.
Set and map are unordered storage elements. They can only be accessed through the interfaces provided by it;
Set: set, which is used to determine whether an element is in a group and is rarely used;Map: ing, which is equivalent to a diction
In GIS, maps are generally divided into two categories: raster maps and vector maps, and raster maps are digital photographs, but some satellites. They have a common feature, that is, they are made up of many pixels, the pixel size is consistent, the row height and the column width are consistent, from this point of view, a remote sensing image is like a grid.Vector maps are made up of many elements, each with its own geographical coordinates, based o

With the enhancement of the computing ability of terminal equipment, users need more and more interactive effect when they use the map.For example, in today's very hot indoor navigation, in order to get a good user experience, it is necessary to change the color of the store when a user clicks on a store. This requires that vector layers be superimposed.How can I overlay a vector layer on top of a tile
search speed is relatively high.
5.The key of a map must be unique.
6.The stack adapter must be used with other containers. The default internal container in STL is deque. First, only one exit is available, and traversal is not allowed.
7.Queue is a restricted deque. It is easier to use a list for internal containers. First-in-first-out, traversal not allowed.
Below are some guidelines for selecting the sequence container type
1. If we need to random

When deleting an element in a vector, the following elements are moved forward by one place, so the original iterators are invalid.
After deleting the first number 4 greater than 3: 0 1 2 3 5 6 7 8 9
---> But now the iterator points to 5, ITER ++ points to 6 again, and 5 is missing... As a result, 5, 7, and 9 are not deleted.
Method of modification: In lo
: lower_bound (const keytype X), upper_bound (const keytype X) you can find the first element of a key value smaller than the specified key value x and the first element of a key value greater than the specified key value x. The returned value is the cursor of the element.
Details: when the maximum value of key value x is reached, upper_bound returns the end cursor of this multimap. Similarly, when the key value x is already the smallest, lower_bound returns the begin cursor of the multimap.

using animatedvectordrawable, animatedvectordrawable resources are placed in the DRAWABLE-V21 directory, and the drawable provides a Animatedvectordrawable the same name as the resource to be used in versions prior to 5.0, in this XML file you can use a selector to replace the animation.Note that sometimes for brevity it may be possible to put vectordrawable under the Pathdata in String.xml, and then refer to it under vectordrawable, such as:path android:name="right_arm" android:fillColor
1, vector (continuous space storage, you can use the [] operator) can quickly access random elements, quickly inserted at the end of the element, but in the middle of the sequence randomly inserted , delete elements are slow. Also, if there is not enough space at the outset, there is a process to reallocate more space.2, deque (small piece of continuous, small sheet connected with the linked list, in fact there is a
Sequent container: (vector)Erase not only invalidates all iterators pointing to the deleted element, but also invalidates all iterators after the deleted element. Therefore, the erase (ITER ++) method cannot be used, however, the returned value of erase is the next effective iterator.
The correct method is ::For (iter = C. Begin (); iter! = C. End ();)
Iter = C. Erase (ITER );
Associated container: (MAP)The
