template < 
   class Elem,  
   class Tr = char_traits<Elem>,  
   class Alloc = allocator<Elem>  
> 
   class basic_istringstream : public basic_istream<Elem, Tr>

Parameters

  • Alloc
    The allocator class.

  • Elem
    The type of the basic element of the string.

  • Tr
    The character traits specialized on the basic element of the string.

Remarks

The object stores an object of class basic_stringbuf<Elem, Tr, Alloc>.

Typedefs

allocator_type

The type is a synonym for the template parameter Alloc.
