java.lang.Object

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

org.apache.flink.api.java.typeutils.WritableTypeInfo<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 WritableTypeInfo<T extends org.apache.hadoop.io.Writable>
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 Hadoop's Writable interface. The Writable interface defines the serialization and deserialization routines for the data type.
