Detailed Description

template<class ContainerType>
class Foam::Circulator< ContainerType >

Walks over a container as if it were circular. The container must have the following members defined:

- value_type

size_type
difference_type
iterator
reference

Examples

face f(identity(5));
// Construct Circulator from the face
Circulator<face> circ(f);
// First check that the Circulator has a size to iterate over.
// Then circulate around the list starting and finishing at the fulcrum.
if (circ.size()) do
{
    circ() += 1;
    Info<< "Iterate forwards over face : " << circ() << endl;
} while (circ.circulate(CirculatorBase::direction::clockwise));
