Detailed Description

template<class ContainerType>
class Foam::ConstCirculator< ContainerType >

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

- value_type

  • size_type
  • difference_type
  • const_iterator
  • const_reference

Examples:

face f(identity(5));
// Construct circulator from the face
ConstCirculator<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
{
Info<< "Iterate forwards over face : " << circ() << endl;
} while (circ.circulate(CirculatorBase::direction::clockwise));
face f(identity(5));
ConstCirculator<face> circClockwise(f);
ConstCirculator<face> circAnticlockwise(f);
if (circClockwise.size() && circAnticlockwise.size()) do
{
Info<< "Iterate forward over face :" << circClockwise() << endl;
Info<< "Iterate backward over face:" << circAnticlockwise() << endl;
}
while
(
circClockwise.circulate(CirculatorBase::direction::clockwise),
circAnticlockwise.circulate
(
)
);
