collection_adapter::difference_type (STL/CLR)
The types of a signed distance between two elements.
typedef int difference_type;
Remarks
The type describes a signed element count.
Example
// cliext_collection_adapter_difference_type.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();
// compute positive difference
Mycoll::difference_type diff = 0;
Mycoll::iterator it = c1.begin();
for (; it != c1.end(); ++it)
++diff;
System::Console::WriteLine("end()-begin() = {0}", diff);
return (0);
}
a b c end()-begin() = 3
