std::share_ptr智能指针：
http://en.cppreference.com/w/cpp/memory/shared_ptr
智能指针shared_ptr<_class>，在<memory>中定义。
表示_class类型的指针，通过引用计数的方式避免指针错误；
std::unique_ptr
std::tr1::function模板类：
#include <tr1/functional>
typedef std::tr1::function<void (int)> HandlerEvent;
在C++的TR1中(Technology Report)中包含一个function模板类和bind模板函数，使用它们可以实现类似函数指针的功能。
function<void()> f(_f);//???
在类的内部叫上Internal类(private);
vector<char> *data
-----function::member-----
stringstream:
#include <sstream>
C++引入了ostringstream、istringstream、stringstream这三个类，要使用他们创建对象就必须包含sstream.h头文件。
set/vector/map:
#include <set>
#include <map>
#include <vector>
set::insert(object);
std::vector
|
Defined in header <vector> |
|
template< class T, class Allocator = std::allocator<T> > class vector; |
std::vector is a sequence container that encapsulates dynamic size arrays.
|
The elements are stored contiguously, which means that elements can be accessed not only through iterators, but also using offsets on regular pointers to elements. This means that a pointer to an element of a vector may be passed to any function that expects a pointer to an element of an array. |
map是关联式容器；
static_cast<class > (expression):
meaning:
return EventManager*'s object equal arg;
static_cast<new_type> (expression);
#include <algrithm>
pop *_Frist to *(_Last-1) and reheap,using _Pred;
shared_from_this();
std::enable_shared_from_this::shared_from_this;
|
shared_ptr<T> shared_from_this(); |
(1) |
|
shared_ptr<T const> shared_from_this() const; |
(2) |
Returns a std::shared_ptr<T> that shares ownership of *this with all existing std::shared_ptr that refer to *this.
