* get a callable which will be able to transform the results into

* viewable and understable string.
|

*
|
|
* The callable will have only one argument: the `value` to translate.
|
|
*
|
|
* The callable should also be able to return a key `_header`, which
|
|
* will contains the header of the column.
|
|
*
|
|
* The string returned **must** be already translated if necessary,
|
|
* **with an exception** for the string returned for `_header`.
|
|
*
|
|
* Example :
|
|
*
|
|
* ```
|
|
* protected $translator;
|
|
*
|
|
* public function getLabels($key, array $values, $data)
|
|
* {
|
|
* return function($value) {
|
|
* case $value

* {
|
|
* case '_header' :

|
* return 'my header not translated';
|
|
* case true:
|
|
* return $this->translator->trans('true');
|
|
* case false:
|
|
* return $this->translator->trans('false');

* default:

* // this should not happens !
|
|
* throw new \LogicException();
|
|
* }
|
|
* }
|
|
* ```
|
|
*
|
|
* **Note:** Why each string must be translated with an exception for
|
|
* the `_header` ? For performance reasons: most of the value will be number
|
|
* which do not need to be translated, or value already translated in
|
|
* database. But the header must be, in every case, translated.
|
|
*
|
|
* @param string $key The column key, as added in the query
|
|
* @param mixed[] $values The values from the result. if there are duplicates, those might be given twice. Example: array('FR', 'BE', 'CZ', 'FR', 'BE', 'FR')
|
|
*
|
|
* @return callable(mixed $value): (string|int|\DateTimeInterface|TranslatableInterface) where the first argument is the value, and the function should return the label to show in the formatted file. Example : `function($countryCode) use ($countries) { return $countries[$countryCode]->getName(); }`
