Description copied from interface: IdentifiedDataSerializable

Returns DataSerializableFactory factory ID for this class.

Returns:

factory ID

getId

public int getId()

Description copied from interface: IdentifiedDataSerializable

Returns type identifier for this class. It should be unique per DataSerializableFactory.

Returns:

type ID
