\ccDefinition
|
|
\cgal\ defines input operators for classes that are derived
|
|
from the class \ccStyle{istream}. This allows to read from istreams
|
|
as \ccStyle{cin}, as well as from strstreams and fstreams.
|
|
The input operator is defined for all classes in the \cgal\ kernel.
|
|
|
|
|
|
\ccFunction{istream& operator>>(istream& is, Class c);}
|
|
{Extracts object \ccStyle{c} from the stream \ccc{is}. Returns \ccc{is}.}
