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

org.geotools.data.Transaction.commit()
Makes all transactions made since the previous commit/rollback permanent.
FeatureSources will need to issue any changes notifications using a FeatureEvent.FEATURES_CHANGED to all FeatureSources with the same typeName and a different Transaction. FeatureSources with the same Transaction will of been notified of changes as the FeaureWriter made them.
@throws DataSourceException if there are any datasource errors. @see #setAutoCommit(boolean)
