RestateRandom (sdk-api 0.7.0 API)

java.lang.Object
- java.util.Random
- - dev.restate.sdk.RestateRandom

All Implemented Interfaces:

java.io.Serializable
```
public class RestateRandom
extends java.util.Random
```
Subclass of Random inherently predictable, seeded on the InvocationId, which is not secret.
This instance is useful to generate identifiers, idempotency keys, and for uniform sampling from a set of options. If a cryptographically secure value is needed, please generate that externally using RestateContext.sideEffect(Serde, ThrowingSupplier).
You MUST NOT use this object inside a RestateContext.sideEffect(Serde, ThrowingSupplier).
