Examples of org.geotools.data.Transaction.rollback()

org.geotools.data.Transaction.rollback()
Undoes all transactions made since the last commit or rollback.
FeatureSources will need to issue any changes notifications using a FeatureEvent.FEATURES_CHANGED. This will need to be issued to all FeatureSources with the same typeName and Transaction.
@throws DataSourceException if there are problems with the datasource. @throws UnsupportedOperationException if the rollback method is notsupported by this datasource. @see #setAutoCommit(boolean)

  @Override
  protected void doRollback(DefaultTransactionStatus status) {
    GeoToolsTransactionObject txObject = (GeoToolsTransactionObject) status.getTransaction();
    Transaction tx = txObject.getTransactionHolder().getTransaction();
    try {
      tx.rollback();
    } catch (IOException e) {
      log.warn(e.getMessage(), e);
