Interface RawValueData<T>

Type Parameters:

T - originating class for the raw value

All Known Implementing Classes:

BinaryRawValueData

@PublicEvolving
public interface RawValueData<T>

An internal data structure representing data of RawType.

This data structure is immutable.

Method Summary

Modifier and Type	Method and Description
static <T> RawValueData<T>	fromBytes(byte[] bytes) Creates an instance of RawValueData from the given byte array.
static <T> RawValueData<T>	fromObject(T javaObject) Creates an instance of RawValueData from a Java object.
byte[]	toBytes(org.apache.flink.api.common.typeutils.TypeSerializer<T> serializer) Converts this RawValueData into a byte array.
T	toObject(org.apache.flink.api.common.typeutils.TypeSerializer<T> serializer) Converts this RawValueData into a Java object.

Method Detail

toObject

T toObject(org.apache.flink.api.common.typeutils.TypeSerializer<T> serializer)

Converts this RawValueData into a Java object.

The given serializer is required because the "raw value" might be represented in a binary format and needs to be deserialized first.

Note: The returned Java object may be reused.

toBytes

byte[] toBytes(org.apache.flink.api.common.typeutils.TypeSerializer<T> serializer)

Converts this RawValueData into a byte array.

The given serializer is required because the "raw value" might be still be a Java object and needs to be serialized first.

Note: The returned byte array may be reused.

fromObject

static <T> RawValueData<T> fromObject(T javaObject)

Creates an instance of RawValueData from a Java object.

fromBytes

static <T> RawValueData<T> fromBytes(byte[] bytes)

Creates an instance of RawValueData from the given byte array.
