示例1: generate

/**
* Kicks off DAL generation.
* @param tables the cassandra table meta data
* @throws IOException if write to file fails
*/

// if there is only 1 key or there's just the partition key without clustering keys
if (isSingleValueKeyedTable(table)) {
accessorBuilder.addMethod(generateAll(table, entityTable));
