Name
EmptyFieldIterator —
Iterate over a Field with no components
C++ Synopsis
#include "engine/fieldindex.h"
class EmptyFieldIterator: , publicComponentIterator{EmptyFieldIterator();
}
Description
EmptyFieldIterator is the
ComponentIterator for EmptyFieldComponents.
It is used when iterating over the nonexistent components of
nonexistent Fields, such as the out-of-plane part of an
in-plane Field. A loop using an
EmptyFieldIterator does nothing.
Dereferencing the iterator produces a null pointer.
This isn't as silly as it seems. It's used in generic code
where the type of Field isn't known.
EmptyFieldIterators are created by the
begin() and end()
methods of EmptyFieldComponents,
and are not directly accessible in Python.
