DigiComp.Sequence

This is a very simple and stupid tool, helping in generation of gapless sequences. For this task it relies on key integrity of the database of your choice.

Usage is quite simple also:

/**
 * @param \DigiComp\Sequence\Service\SequenceNumberGenerator $sequenceNumberGenerator
 */
public function __construct(SequenceNumberGenerator $sequenceNumberGenerator) 
{
	$this->orderId = $sequenceNumberGenerator->getNextNumberFor($this);		
}

getNextNumberFor allows you to give an object which will be resolved to its FQCN or a custom sequence name.

The CommandController helps you to advance the current sequence number, in case of migrations or similar.

See ./flow help sequence:advance if interested.
