Package org.apache.flink.table.data.binary

Class BinaryRawValueData<T>

java.lang.Object

org.apache.flink.table.data.binary.LazyBinaryFormat<T>

org.apache.flink.table.data.binary.BinaryRawValueData<T>

Type Parameters:

T - the java type of the raw value.

All Implemented Interfaces:

BinaryFormat, RawValueData<T>

@Internal
public final class BinaryRawValueData<T>
extends LazyBinaryFormat<T>
implements RawValueData<T>

A lazily binary implementation of RawValueData which is backed by MemorySegments and generic Object.

Either MemorySegments or Object must be provided when constructing BinaryRawValueData. The other representation will be materialized when needed.

Method Detail

toObject

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

Description copied from interface: RawValueData

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.

Specified by:

toObject in interface RawValueData<T>

toBytes

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

Description copied from interface: RawValueData

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.

Specified by:

toBytes in interface RawValueData<T>

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object

toString

public String toString()

Overrides:

toString in class Object

materialize

protected BinarySection materialize(org.apache.flink.api.common.typeutils.TypeSerializer<T> serializer)

Description copied from class: LazyBinaryFormat

Materialize java object to binary format. Inherited classes need to hold the information they need. (For example, RawValueData needs javaObjectSerializer).

Specified by:

materialize in class LazyBinaryFormat<T>

fromObject

public static <T> BinaryRawValueData<T> fromObject(T javaObject)

Creates a BinaryRawValueData instance from the given Java object.

fromBytes

public static <T> BinaryRawValueData<T> fromBytes(byte[] bytes)

Creates a BinaryStringData instance from the given bytes.

fromBytes

public static <T> BinaryRawValueData<T> fromBytes(byte[] bytes,
                                                  int offset,
                                                  int numBytes)

Creates a BinaryStringData instance from the given bytes with offset and number of bytes.
