All classes in the CGAL kernel provide input and output operators for I/O streams. The basic task of such an operator is to produce a representation of an object that can be written as a sequence of characters on devices as a console, a file, or a pipe. In CGAL we distinguish between a raw ASCII, a raw binary and a pretty printing format.

All classes in the CGAL kernel provide input and output operators for I/O streams. CGAL provides three different printing mode, defined in the enum IO::Mode , as well as different functions to set and get the printing mode.

Classes
class	CGAL::IO::Color
	An object of the class `Color` is a color available for drawing operations in many CGAL output streams. More...

class	CGAL::Output_rep< T, F >
	The purpose of `Output_rep` is to provide a way to control output formatting that works independently of the object's stream output operator. More...

class	CGAL::Input_rep< T >
	The definition of `Input_rep` is completely symmetric to `Output_rep`. More...

class	CGAL::Istream_iterator< T, Stream >
	The class `Istream_iterator` is an input iterator adaptor for the input stream class `Stream` and value type `T`. More...

class	CGAL::Ostream_iterator< T, Stream >
	The class `Ostream_iterator` is an output iterator adaptor for the output stream class `Stream` and value type `T`. More...

class	CGAL::Verbose_ostream
	The class `Verbose_ostream` can be used as an output stream. More...
