org.odpi.openmetadata.openconnectors.governancedaemonconnectors.openlineageconnectors.janusconnector.graph.LineageGraphTransactionManager

public class LineageGraphTransactionManager
extends Object

Utility class responsible with transaction commits for operations done on the graph. Wraps incoming functional interfaces in a try/catch block, calls their specific method and commits the transaction.
