calculateBitSetInBytes

public static int calculateBitSetInBytes(int arity)

duplicate

public Serializer<InternalRow> duplicate()

从接口复制的说明: Serializer

Creates a deep copy of this serializer if it is necessary, i.e. if it is stateful. This can return itself if the serializer is not stateful.

We need this because Serializers might be used in several threads. Stateless serializers are inherently thread-safe while stateful serializers might not be thread-safe.

指定者:

duplicate 在接口中 Serializer<InternalRow>

copy

public InternalRow copy(InternalRow from)

从接口复制的说明: Serializer

Creates a deep copy of the given element in a new element.

指定者:

copy 在接口中 Serializer<InternalRow>

参数:

from - The element reuse be copied.

返回:

A deep copy of the element.

serialize

public void serialize(InternalRow record,
                      DataOutputView target)
               throws IOException

从接口复制的说明: Serializer

Serializes the given record to the given target output view.

指定者:

serialize 在接口中 Serializer<InternalRow>

参数:

record - The record to serialize.

target - The output view to write the serialized data to.

抛出:

IOException - Thrown, if the serialization encountered an I/O related error. Typically raised by the output view, which may have an underlying I/O channel to which it delegates.

deserialize

public InternalRow deserialize(DataInputView source)
                        throws IOException

从接口复制的说明: Serializer

De-serializes a record from the given source input view.

指定者:

deserialize 在接口中 Serializer<InternalRow>

参数:

source - The input view from which to read the data.

返回:

The deserialized element.

抛出:

IOException - Thrown, if the de-serialization encountered an I/O related error. Typically raised by the input view, which may have an underlying I/O channel from which it reads.

equals

public boolean equals(Object o)

覆盖:

equals 在类中 Object

hashCode

public int hashCode()

覆盖:

hashCode 在类中 Object

serializeToBytes

public byte[] serializeToBytes(InternalRow record)

deserialize

public InternalRow deserialize(byte[] bytes)
