Method Detail

serialize

public void serialize(RowPosition pos,
                      DataOutputPlus out,
                      int version)
               throws java.io.IOException

Description copied from interface: IPartitionerDependentSerializer

Serialize the specified type into the specified DataOutputStream instance.

Specified by:

serialize in interface IPartitionerDependentSerializer<RowPosition>

Parameters:

pos - 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

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

Description copied from interface: IPartitionerDependentSerializer

Deserialize into the specified DataInputStream instance.

Specified by:

deserialize in interface IPartitionerDependentSerializer<RowPosition>

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

public long serializedSize(RowPosition pos,
                           int version)

Description copied from interface: IPartitionerDependentSerializer

Calculate serialized size of object without actually serializing.

Specified by:

serializedSize in interface IPartitionerDependentSerializer<RowPosition>

Parameters:

pos - object to calculate serialized size

version - protocol version

Returns:

serialized size of object t
