UserDefinedType (Flink : Table : Common 2.1.0 API)

java.lang.Object
- org.apache.flink.table.types.logical.LogicalType
- - org.apache.flink.table.types.logical.UserDefinedType

All Implemented Interfaces:

Serializable

Direct Known Subclasses:

DistinctType, StructuredType
```
@PublicEvolving
public abstract class UserDefinedType
extends LogicalType
```
Logical type of a user-defined representation for one or more built-in types. A user-defined type is either a distinct type or a structured type.
A UserDefinedType instance is the result of a catalog lookup or an inline definition (for structured types only).
NOTE: Compared to the SQL standard, this class and subclasses have extensions and are incomplete. We might add new features such as method declarations in the future.
