[jira] [Updated] (FLINK-12412) Allow ListTypeInfo used for
java.util.List and MapTypeInfo used for java.util.Map
[ https://issues.apache.org/jira/browse/FLINK-12412?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]
YangFei updated FLINK-12412:
----------------------------
Description:
public static class UserBehavior
{
public long userId;
public long itemId; public int categoryId; public long timestamp; public List<String> comments; }
public static void main(String[] args) throws Exception
{ PojoTypeInfo<UserBehavior> pojoType = (PojoTypeInfo<UserBehavior>) TypeExtractor.createTypeInfo(UserBehavior.class); }
);
}
The filed `comments` in `UserBehavior` will be extracted by TypeExtractor to `GenericType` .
I think it can be extracted to ListTypeInfo .
This would be a big improvement as in many cases classes including List or Map
