Class ClassPathExplorer

java.lang.Object

in.virit.vwscdn.ClassPathExplorer

public class ClassPathExplorer
extends Object

Utility class to collect widgetset related information from classpath. Utility will seek all directories from classpaths, and jar files having "Vaadin-Widgetsets" key in their manifest file.

Used by WidgetMapGenerator and ide tools to implement some monkey coding for you.

Developer notice: If you end up reading this comment, I guess you have faced a sluggish performance of widget compilation or unreliable detection of components in your classpaths. The thing you might be able to do is to use annotation processing tool like apt to generate the needed information. Then either use that information in WidgetMapGenerator or create the appropriate monkey code for gwt directly in annotation processor and get rid of WidgetMapGenerator. Using annotation processor might be a good idea when dropping Java 1.5 support (integrated to javac in 6).
