Class StreamData

java.lang.Object
  wt.fc.WTObject
      wt.content.StreamData

All Implemented Interfaces:

DisplayIdentification, Externalizable, NetFactor, ObjectMappable, Persistable, Revaultable, Serializable, Streamed, UniquelyIdentifiedContent

public class StreamData

extends WTObject

implements Streamed, Externalizable

This is where the class where the bulk data is actually stored. It is referenced as an ObjectReference from the ApplicationData class.

Use the newStreamData static factory method(s), not the StreamData constructor, to construct instances of this class. Instances must be constructed using the static factory(s), in order to ensure proper initialization of the instance.

Supported API: false

Extendable: false
