public function getColumns() {
$schema = $this->getSchema();
// A typical use case for the method is to iterate on the columns, while
// some other use cases rely on identifying the first column with the key()
// function. Since the schema is persisted in the Field object, we take care
// of resetting the array pointer so that the former does not interfere with
// the latter.
