Method Details

serialize

public void serialize(Mutation mutation,
 DataOutputPlus out,
 int version)
               throws IOException

Description copied from interface: IVersionedAsymmetricSerializer

Serialize the specified type into the specified DataOutputStream instance.

Specified by:

serialize in interface IVersionedAsymmetricSerializer<Mutation,Mutation>

Parameters:

mutation - type that needs to be serialized

out - DataOutput into which serialization needs to happen.

version - protocol version

Throws:

IOException - if serialization fails

prepareSerializedBuffer

public void prepareSerializedBuffer(Mutation mutation,
 int version)

Called early during request processing to prevent that serialization(Mutation, int) is called concurrently. See org.apache.cassandra.service.StorageProxy#sendToHintedReplicas(Mutation, ReplicaPlan.ForWrite, AbstractWriteResponseHandler, String, Stage)

deserialize

public Mutation deserialize(DataInputPlus in,
 int version,
 DeserializationHelper.Flag flag)
                     throws IOException

Throws:

IOException

deserialize

public Mutation deserialize(DataInputPlus in,
 int version)
                     throws IOException

Description copied from interface: IVersionedAsymmetricSerializer

Deserialize into the specified DataInputStream instance.

Specified by:

deserialize in interface IVersionedAsymmetricSerializer<Mutation,Mutation>

Parameters:

in - DataInput from which deserialization needs to happen.

version - protocol version

Returns:

the type that was deserialized

Throws:

IOException - if deserialization fails

serializedSize

public long serializedSize(Mutation mutation,
 int version)

Description copied from interface: IVersionedAsymmetricSerializer

Calculate serialized size of object without actually serializing.

Specified by:

serializedSize in interface IVersionedAsymmetricSerializer<Mutation,Mutation>

Parameters:

mutation - object to calculate serialized size

version - protocol version

Returns:

serialized size of object t
