Class VisualStyle

java.lang.Object

edu.internet2.middleware.grouper.app.visualization.VisualStyle

public class VisualStyle
extends Object

A visual style containing a set of properties as defined in grouper.properties. The property names are strings that map to a string value. The values can be null (since GrouperConfig doesn't easily read in blank values), so callers should query properties using the optional default if non-null properties are required. If the style has a property for "inherit", retrieval will look into its inherited style hierarchy, recursively, until it finds a non-null value.
