| [section:intro Introduction] |
| |
| The Boost type-traits library contains a |
| set of very specific traits classes, each of which encapsulate a single trait |
| from the C++ type system; for example, is a type a pointer or a reference type? |
| Or does a type have a trivial constructor, or a const-qualifier? |
| |
| The type-traits classes share a unified design: each class inherits from |
| the type __true_type if the type has the specified property and inherits from |
| __false_type otherwise. |
| |
| The type-traits library also contains a set of classes that perform a |
| specific transformation on a type; for example, they can remove a |
| top-level const or volatile qualifier from a type. Each class that |
| performs a transformation defines a single typedef-member `type` |
| that is the result of the transformation. |
