Examples of executeInTransaction()

com.graphaware.tx.executor.single.SimpleTransactionExecutor.executeInTransaction()
{@inheritDoc}
com.graphaware.tx.executor.single.TransactionExecutor.executeInTransaction()
Execute work in a single transaction, using {@link RethrowException} as {@link ExceptionHandlingStrategy}. @param callback specifying the work to be executed. @param < T> type of execution result. If no result is expected, this should be {@link com.graphaware.tx.executor.NullItem}. It could also be {@link Void} (but the former is generally preferred). @return result of the execution. @throws RuntimeException if any occurred during the transaction.
com.hp.hpl.jena.graph.TransactionHandler.executeInTransaction()
If transactions are supported, execute the command c within a transaction and return its result. If not, throw an UnsupportedOperationException.
