Example 1 with Manifest

use of scala.reflect.Manifest in project parquet-mr by apache.

the class ScroogeStructConverter method convertClassToThriftType.

 * In composite types,  such as the type of the key in a map, since we use reflection to get the type class, this method
 * does conversion based on the class provided.
