> Add helper methods for all built-in Flink types to Types
> --------------------------------------------------------
>
> Key: FLINK-7452
> URL: https://issues.apache.org/jira/browse/FLINK-7452
> Project: Flink
> Issue Type: Improvement
> Components: Type Serialization System
> Reporter: Timo Walther
> Assignee: Timo Walther
> Fix For: 1.5.0
>
>
> Sometimes it is very difficult to provide `TypeInformation` manually, in case
> some extraction fails or is not available. {{TypeHint}}s should be the
> preferred way but this methods can ensure correct types.
> I propose to add all built-in Flink types to the {{Types}}. Such as:
> {code}
> Types.POJO(MyPojo.class)
> Types.POJO(Map<String, TypeInformation>)
> Types.GENERIC(Object.class)
> Types.TUPLE(TypeInformation, ...)
> Types.MAP(TypeInformation, TypeInformation)
> {code}
> The methods should validate that the returned type is exactly the requested
> type. And especially in case of POJO should help creating {{PojoTypeInfo}}.
> Once this is in place, we can deprecate the {{TypeInfoParser}}.
