Example 1 with DataSetMetadataBuilder

use of org.talend.dataprep.dataset.DataSetMetadataBuilder in project data-prep by Talend.

the class DataSetService method updateRawDataSet.

/**
 * Updates a data set content and metadata. If no data set exists for given id, data set is silently created.
 *
 * @param dataSetId The id of data set to be updated.
 * @param name The new name for the data set. Empty name (or <code>null</code>) does not update dataset name.
 * @param dataSetContent The new content for the data set. If empty, existing content will <b>not</b> be replaced.
 * For delete operation, look at {@link #delete(String)}.
