queue::queue (STL/CLR)

 

Constructs a container adapter object.

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

right

Object to copy.

wrapped

Wrapped container to use.

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); 
    } 

size() = 0
