from their granularity and orthogonality. Boost has probably diluted the

distinction in the <a href="../libs/utility/iterator_adaptors.htm">Iterator

Adaptors</a> library, where we transmit all of an adapted iterator's

behavior in a single policies class.

|
+ <p>An <i>adaptor</i> is a class template which builds on another type or
|
|
|
+ types to provide a new interface or behavioral variant. Examples of
|
|
|
+ standard adaptors are <a href=
|
|
|
+ "http://www.sgi.com/tech/stl/ReverseIterator.html">std::reverse_iterator</a>,
|
|
|
+ which adapts an iterator type by reversing its motion upon
|
|
|
+ increment/decrement, and <a href=
|
|
|
+ "http://www.sgi.com/tech/stl/stack.html">std::stack</a>, which adapts a
|
|
|
+ container to provide a simple stack interface.
