CGAL::operator>>
Definition
CGAL defines input operators for classes that are derived
from the class istream. This allows to read from istreams
as cin, as well as from strstreams and fstreams.
The input operator is defined for all classes in the CGAL kernel.

istream&
|
istream& is
>>
Class c
|
Extracts object c from the stream is. Returns is.
