TransactionDataImpl (IBM FHIR Server)

java.lang.Object
- com.ibm.fhir.persistence.jdbc.dao.impl.TransactionDataImpl<T>

All Implemented Interfaces:

TransactionData
```
public class TransactionDataImpl<T extends TransactionData>
extends Object
implements TransactionData
```
Hold data accumulated during a transaction which we want to persist just prior to commit. Because multiple datasources could be involved in a distributed transaction, we need to hold TransactionData for each. Note that because all of this relates to a single transaction, this also means that it's a single thread, so there are no concurrency issues.
