queue::queue (STL/CLR)

 

The new home for Visual Studio documentation is Visual Studio 2017 Documentation on docs.microsoft.com.

The latest version of this topic can be found at queue::queue (STL/CLR).

Constructs a container adapter object.

Syntax

queue();  
queue(queue<Value, Container>% right);  
queue(queue<Value, Container>^ right);  
explicit queue(container_type% wrapped);  

Parameters

right
Object to copy.

wrapped
Wrapped container to use.

Remarks

The constructor:

queue();

creates an empty wrapped container. You use it to specify an empty initial controlled sequence.

The constructor:

queue(queue<Value, Container>% right);

creates a wrapped container that is a copy of right.get_container(). You use it to specify an initial controlled sequence that is a copy of the sequence controlled by the queue object right.

The constructor:

queue(queue<Value, Container>^ right);

creates a wrapped container that is a copy of right->get_container(). You use it to specify an initial controlled sequence that is a copy of the sequence controlled by the queue object *right.

The constructor:

explicit queue(container_type wrapped);

uses the existing container wrapped as the wrapped container. You use it to construct a queue from an existing container.

Example

// cliext_queue_construct.cpp   
// compile with: /clr   
#include <cliext/queue>   
#include <cliext/list>   
  
typedef cliext::queue<wchar_t> Myqueue;   
typedef cliext::list<wchar_t> Mylist;   
typedef cliext::queue<wchar_t, Mylist> Myqueue_list;   
int main()   
    {   
// construct an empty container   
    Myqueue c1;   
    System::Console::WriteLine("size() = {0}", c1.size());   
  
// construct from an underlying container   
    Mylist v2(5, L'x');   
    Myqueue_list c2(v2);       
    for each (wchar_t elem in c2.get_container())   
        System::Console::Write(" {0}", elem);   
    System::Console::WriteLine();   
  
// construct by copying another container   
    Myqueue_list c3(c2);   
    for each (wchar_t elem in c3.get_container())   
        System::Console::Write(" {0}", elem);   
    System::Console::WriteLine();   
  
// construct by copying another container through handle   
    Myqueue_list c4(%c2);   
    for each (wchar_t elem in c4.get_container())   
        System::Console::Write(" {0}", elem);   
    System::Console::WriteLine();   
    return (0);   
    }
