collection_adapter::begin (STL/CLR)

Designates the beginning of the controlled sequence.

    iterator begin();

Remarks

The member function returns an input iterator that designates the first element of the controlled sequence, or just beyond the end of an empty sequence.

Example

// cliext_collection_adapter_begin.cpp 
// compile with: /clr 
#include <cliext/adapter> 
#include <cliext/deque> 
 
typedef cliext::collection_adapter< 
    System::Collections::ICollection> Mycoll; 
int main() 
    { 
    cliext::deque<wchar_t> d1; 
    d1.push_back(L'a'); 
    d1.push_back(L'b'); 
    d1.push_back(L'c'); 
    Mycoll c1(%d1); 
 
// display initial contents " a b c" 
    for each (wchar_t elem in c1) 
        System::Console::Write(" {0}", elem); 
    System::Console::WriteLine(); 
 
// inspect first two items 
    Mycoll::iterator it = c1.begin(); 
    System::Console::WriteLine("*begin() = {0}", *it); 
    System::Console::WriteLine("*++begin() = {0}", *++it); 
    return (0); 
    } 
 

a b c *begin() = a *++begin() = b
