Class ValueTypeInfo<T extends org.apache.flink.types.Value>

java.lang.Object

org.apache.flink.api.common.typeinfo.TypeInformation<T>

org.apache.flink.api.java.typeutils.ValueTypeInfo<T>

Type Parameters:

T - The type of the class represented by this type information.

All Implemented Interfaces:

Serializable, org.apache.flink.api.common.typeinfo.AtomicType<T>

public class ValueTypeInfo<T extends org.apache.flink.types.Value>
extends org.apache.flink.api.common.typeinfo.TypeInformation<T>
implements org.apache.flink.api.common.typeinfo.AtomicType<T>

Type information for data types that extend the Value interface. The value interface allows types to define their custom serialization and deserialization routines.
