| * \brief String literal wrapper |
| * |
| * The \c basic_string_literal is a thin wrapper around a constant string literal. |
| * It provides interface similar to STL strings, but because of read-only nature |
| * of string literals, lacks ability to modify string contents. However, |
| * \c basic_string_literal objects can be assigned to and cleared. |
| * |
| * The main advantage of this class comparing to other string classes is that |
| * it doesn't dynamically allocate memory and therefore is fast, thin and exception safe. |
