CacheTransactionSync (IBM FHIR Server)

java.lang.Object
- com.ibm.fhir.persistence.jdbc.impl.CacheTransactionSync

All Implemented Interfaces:

javax.transaction.Synchronization
```
public class CacheTransactionSync
extends java.lang.Object
implements javax.transaction.Synchronization
```
Adapter to synchronize the thread-local caches with the shared caches when the transaction commits. It's important that we don't share ids created inside a transaction with other threads until the data is committed - those ids are not visible to other threads/transactions (the 'I' in ACID).
