# DigiComp.Sequence
|
|
|
|
This is a very simple 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:
|
|
```php
|
|
/**
|
|
* @param 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 `SequenceCommandController` helps you to advance the current sequence number, in case of migrations or similar. See
|
|
`./flow help sequence:advance` if interested.
