UlidFactory (polaris-toolkit 3.2.53 API)

java.lang.Object
- io.polaris.core.ulid.UlidFactory

```
public final class UlidFactory
extends Object
```
A class that actually generates ULIDs.
This class is used by UlidCreator.
You can use this class if you need to use a specific random generator strategy. However, most people just need UlidCreator.
Instances of this class can behave in one of two ways: monotonic or non-monotonic (default).
If the factory is monotonic, the random component is incremented by 1 If more than one ULID is generated within the same millisecond.
The maximum ULIDs that can be generated per millisecond is 2^80.
