Introduction: This article describes the methods of exporting STL classes and classes containing STL in DLLs. Example source code
DLLs cannot directly export generic templates (generalized template), so if you are exporting an STL class, the
Refer to C + + primer.Vectors are a collection of objects of the same type, each with a corresponding integer index value. As with string objects, the standard library is responsible for managing the associated memory of the storage element. We
[Reprinted] BooleanQuery is useful in search.
In the search, we may encounter different fields in the index file to be searched, and there is an operational relationship with or not between different fields. For example, what keywords must exist in
Java Collection FrameworkBefore Java 2, Java provided the ad hoc class. For example: Dictionary, Vector, Stack, and properties These classes are used to store and manipulate groups of objects.Although these classes are useful, they lack a central,
ArrayList array List collection interface and list interface differences
The list interface expands the collection interface and adds an index-dependent method.
code exampleObject get (int index) object Set (int index,object element)
ArrayList will be faster than vector, he is non-synchronous, if the design involves multi-threading, or vector betterImport java.util.*;/*** Demonstrates the use of vectors. including the creation of vectors, adding elements to vectors, removing
The SDK provides several Java. util. List Implementation interfaces for Ordered Sets. Three of them are most well-known: vector, arraylist, and sorted list. The performance difference between these List classes is a frequently asked question. In

The vector class provides an alternative representation for built-in arrays. Like the string class, the vector class is part of the standard library introduced with standard C ++, to use vector, we must include the relevant header file:

First, about Allocator, next to the stamp → Wikipedia-distributor (C ++)
This time, I only used some of the APIs to implement a simple vector container. This simple version of vector implements simple functions such as insertion, deletion, and
VectorSimilar to the built-in array,It has a continuous memory and the starting address remains unchanged.Therefore, it supports random access, that is, the [] Operator. However, because its memory space is continuous, inserting and deleting in the
Learn about the ICollection interface, iterations, and generic collections, and learn more about the IList interface below.
There are two types of IList interfaces that can be seen through MSDN:
The element is an IList interface of type object,
The basic elements of the Operator programming language, which makes our code more concise and straightforward. However, in order to solve the problem of different types of operands, we have introduced the concept of forced conversion. Let's look at
The Vector class provides the function of increasing the number of groups. As more elements are added to the group, the number groups become larger. After deleting a few elements, the number groups become smaller.Vector has three structure functions,

Silverlight provides a good animation foundation, but it lacks a convenient way to perform animation processing along any geometric path object. In the Windows Presentation Foundation, the animation processing classes doubleanimationusingpath and
Given a binary tree, return the level order traversal of its nodes 'values. (ie, from left to right, level by level ).
For example:Given Binary Tree{3,9,20,#,#,15,7},

Return its level order traversal:

Concept: provides a way to access each element in an aggregate object sequentially without exposing the internal representation of the object.
