Detailed Description

template<class InputIterator, class Letter>
struct utility::Window< InputIterator, Letter >

Handle windows in streams for performing regular expression search.

A window is a portion of a stream, viewable as a string, on which several operations can be performed:

• Read the window's characters.
• Shift the window forward.

A window has a constant size, unless an end of line ('
') or an end of file occurs, in which case a window is shorter than its supposed size.

Parameters:

InputIterator	The type of input iterator used to read the stream. It shall be a random access iterator.
Letter	The type used for letters.
