类 BinaryRawValueData<T>

java.lang.Object

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

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

类型参数:

T - the java type of the raw value.

所有已实现的接口:

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.

方法详细资料

toObject

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

从接口复制的说明: 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.

指定者:

toObject 在接口中 RawValueData<T>

toBytes

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

从接口复制的说明: 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.

指定者:

toBytes 在接口中 RawValueData<T>

equals

public boolean equals(Object o)

覆盖:

equals 在类中 Object

hashCode

public int hashCode()

覆盖:

hashCode 在类中 Object

toString

public String toString()

覆盖:

toString 在类中 Object

materialize

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

从类复制的说明: LazyBinaryFormat

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

指定者:

materialize 在类中 LazyBinaryFormat<T>

fromObject

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

Creates a BinaryRawValueData instance from the given Java object.

指定者:

fromObject 在接口中 RawValueData<T>

fromBytes

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

Creates a BinaryStringData instance from the given bytes.

指定者:

fromBytes 在接口中 RawValueData<T>

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.
