Examples of ListTypeInfo

org.apache.hadoop.hive.serde2.typeinfo.ListTypeInfo
A List Type has homogeneous elements. All elements of the List has the same TypeInfo which is returned by getListElementTypeInfo. Always use the TypeInfoFactory to create new TypeInfo objects, instead of directly creating an instance of this class.
