Class SimpleData

java.lang.Object

diva.util.xml.AbstractXmlBuilder

diva.sketch.recognition.SimpleData

All Implemented Interfaces:

TypedData, XmlBuilder

public final class SimpleData
extends AbstractXmlBuilder
implements TypedData

An instance of typed data that represents dynamic, user-defined types. If you are writing a low-level recognizer and that recognizes strokes based on a feature vector and knows nothing about the semantics of the recognition, other than a string representation of the type, then this is the class for you (e.g. new SimpleData("scribble")). However, if you have semantic knowledge of the data that is being represented, e.g. the number of sides on the polygon that you just recognized, then you should probably be a statically-typed form of TypedData (e.g. PolygonData).
