public abstract class Data

extends java.lang.Object

implements java.io.Serializable

Contains a single piece of data. Used to wrap data for use in the PTK. All Data objects have an id field. This is set by the creator of the Data and indentifies it. It is typically some string that describes the data, such as "sound" or "temperature". Some data ids are already specified in PTKConstants.
