TransactionId (OpenAM Server Only 7.2.2 Documentation)

java.lang.Object
- org.forgerock.services.TransactionId

```
public final class TransactionId
extends Object
```
TransactionId value should be unique per request coming from an external agent so that all events occurring in response to the same external stimulus can be tied together. Calls to external systems should propagate the value returned by createSubTransactionId() so that Audit events reported by the external system can also be tied back to the original stimulus. Due to the fact that each TransactionId instance creates a sequence of sub-transaction IDs, the same TransactionId object should be used while fulfilling a given request; it is not appropriate to create multiple instances of TransactionId with the same value as this would lead to duplicate sub-transaction ID values. As such, two instances of TransactionId with the same value are not considered equal. This class is thread-safe.
