Interface IPartitionerDependentSerializer<T>

All Known Implementing Classes:

AbstractBounds.AbstractBoundsSerializer, RowPosition.RowPositionSerializer, Token.TokenSerializer

public interface IPartitionerDependentSerializer<T>

Versioned serializer where the serialization depends on partitioner. On serialization the partitioner is given by the entity being serialized. To deserialize the partitioner used must be known to the calling method.

Method Summary

Methods

Modifier and Type	Method and Description
T	deserialize(java.io.DataInput in, IPartitioner p, int version) Deserialize into the specified DataInputStream instance.
void	serialize(T t, DataOutputPlus out, int version) Serialize the specified type into the specified DataOutputStream instance.
long	serializedSize(T t, int version) Calculate serialized size of object without actually serializing.

Method Detail

serialize

void serialize(T t,
             DataOutputPlus out,
             int version)
               throws java.io.IOException

Serialize the specified type into the specified DataOutputStream instance.

Parameters:

t - type that needs to be serialized

out - DataOutput into which serialization needs to happen.

version - protocol version

Throws:

java.io.IOException - if serialization fails

deserialize

T deserialize(java.io.DataInput in,
            IPartitioner p,
            int version)
              throws java.io.IOException

Deserialize into the specified DataInputStream instance.

Parameters:

in - DataInput from which deserialization needs to happen.

p - Partitioner that will be used to construct tokens. Needs to match the partitioner that was used to serialize the token.

version - protocol version

Returns:

the type that was deserialized

Throws:

java.io.IOException - if deserialization fails

serializedSize

long serializedSize(T t,
                  int version)

Calculate serialized size of object without actually serializing.

Parameters:

t - object to calculate serialized size

version - protocol version

Returns:

serialized size of object t
