Package org.linuxforhealth.fhir.persistence.jdbc.connection

Class FHIRTestTransactionAdapter

java.lang.Object

org.linuxforhealth.fhir.persistence.jdbc.connection.FHIRTestTransactionAdapter

All Implemented Interfaces:

FHIRPersistenceTransaction

public class FHIRTestTransactionAdapter
extends java.lang.Object
implements FHIRPersistenceTransaction

Hides the logic behind obtaining a JDBC Connection from the DAO code. Use by unit tests or other scenarios where connections are obtained using an IConnectionProvider implementation, outside the scope of a JEE container. Transactions are managed with the help of the SimpleTransactionProvider and wrapped by this class, meaning we have a uniform interface for handling transactions across JEE and unit-test scenarios.
