Starting with 5.0 (API level 21), Android is starting to support vector graphics. What is the vector map and the vector map has any advantages and disadvantages is not covered in this article, the specific reference vector map encyclopedia. But here's the advantage:

Reproduced in: http://blog.csdn.net/longshengguoji/article/details/8507394The vector class, known as the vectors class, implements a dynamic array, an array of objects used to change the number of elements. Like arrays, the vector class also represents the position of the element with a subscript starting from 0, but the array is different when the vector object

Andre Lamothe said: "vector ry is the best friend of game programmers ". It is not false. Vector RY's position in game programming cannot be ignored, because in the eyes of game programmers, the display screen is a coordinate
A vector is a class in the Java.util package that implements a function similar to a dynamic array.Vectors and arrays are similar and can hold a set of data (data lists). But the size of the array is fixed, and once specified, it cannot be changed, while the vector provides a function similar to "dynamic array", one of the important differences between vectors and arrays is that the capacity of vectors is v
The built-in arrays in C ++ support the container mechanism, but they do not support the abstract semantics of containers. To solve this problem, we need to implement such a class. In standard C ++, container vector is used. The container vector is also a class template.Use the header file # include

concept will be elaborated. The main purpose of the blog is to make notes for themselves to remind.All right, it's officially started.Vector, Chinese is the "vector", how difficult to understand the name, vectors is clearly the concept of geometry, okay? Before the vector or foggy, listen to the students bragging about using vectors to do the storage, really worship a, in fact, this thing is an array of pl
Vector is part of the C ++ standard template library. It is a versatile template class and function library that can operate on multiple data structures and algorithms. Vector is considered a container because it can store various types of objects like a container. Simply put, vector is a dynamic array that can store any type, data can be added and compressed.

A vector class is called a Vector class. It implements a dynamic array and is used as an array of objects with variable element quantity. Like an array, the vector class uses subscript

Use of vector in C ++
Vector is the most common container in STL. It is an ordered container that supports random access. Simply put, vector is a dynamic array that can store any type of data, but the array is a static allocation space. Once the space is allocated, the size cannot be changed, but the vector is dynamica
Use of Vector
The underlying Array Structure of the vector class, which contains components that can be accessed using integer indexes. However, the vector size can be increased or reduced as needed to meet the needs of adding or removing items after the vector is created. Therefore, you do not need to consider whether
1) Quantity: Also called scalar, pure quantity, only the size has no direction, can use a numerical value to determine;2) Vector: Also known as vector, describing this kind of quantity not only needs the size, but also needs to express its direction;3) directed segment: a segment with a certain length and a definite direction;4) geometric vector: short
Vector Common Methods
assign () assigning values to elements in vectors
void assign (Input_iterator start, Input_iterator end); //void assign (Size_type num, const type VAL);
Reserve () sets the vector smallest element to hold the quantity function to reserve a space for at least a size element for the current vector. (The actual space may be greater than size)

However, the parallel processing potential cannot be fully utilized during actual operation. Vector operations are suitable for the structural characteristics of assembly line computers.

Vector usage in JAVAJava. util. Vector provides a Vector class to implement functions similar to dynamic arrays. There is no pointer concept in the Java language, but correct and flexible use of pointers can indeed greatly improve the quality of the program, for example, the so-called "dynamic array" in C and C ++ is generally implemented by pointers.
