function SequenceDataDefinition::getOrderBy

Gets the description of how the sequence should be sorted.

Only the top level of the array should be sorted. Top-level keys should be discarded when using 'value' sorting. If the sequence is an associative array 'key' sorting is recommended, if not 'value' sorting is recommended.

Return value

string|null May be 'key' (to sort by key), 'value' (to sort by value, discarding keys), or NULL (if the schema does not describe how the sequence should be sorted).
