Method Detail

serialize

public void serialize(RowMutation rm,
                      java.io.DataOutput dos,
                      int version)
               throws java.io.IOException

Description copied from interface: IVersionedSerializer

Serialize the specified type into the specified DataOutputStream instance.

Specified by:

serialize in interface IVersionedSerializer<RowMutation>

Parameters:

rm - type that needs to be serialized

dos - DataOutput into which serialization needs to happen.

version - protocol version

Throws:

java.io.IOException

deserialize

public RowMutation deserialize(java.io.DataInput dis,
                               int version,
                               IColumnSerializer.Flag flag)
                        throws java.io.IOException

Throws:

java.io.IOException

deserializeFixingTimestamps

public RowMutation deserializeFixingTimestamps(java.io.DataInput dis,
                                               int version)
                                        throws java.io.IOException

Used only by o.a.c.service.MigrationManager to fix possibly broken System.nanoTime() timestamps of the schema migrations from remote nodes

Parameters:

dis - The source of the data

version - The version of remote node

Returns:

row mutation with fixed internal timestamps

Throws:

java.io.IOException - If data could not be read

Description copied from interface: IVersionedSerializer

Deserialize into the specified DataInputStream instance.

Specified by:

deserialize in interface IVersionedSerializer<RowMutation>

Parameters:

dis - DataInput from which deserialization needs to happen.

version - protocol version

Returns:

the type that was deserialized

Throws:

java.io.IOException
