Code

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