      edu.umd.cfar.lamp.apploader.propertysheets.ForClassPropertyDescriptor

All Implemented Interfaces:

InstancePropertyDescriptor

public class ForClassPropertyDescriptor

extends ExplicitPropertyDescriptor

An object for manipulating a field on a property sheet. It includes methods for setting and getting the values of the field, as well as displaying it and editing it. It uses the AppLoader preferences model to get information about how to edit the property.

For example, given the RDF description of a property below:

	[	lal:propertyName "AttrName" ;
		props:interfacer :setAttrName ;
		props:renderer :attrConfigNameEditor ;
		props:editor :attrConfigNameEditor ;
		rdfs:label "Name"@en , "Nom"@fr ]
 

Then there must exist a bean with a property given the text description "Name" (in english) that has the java name "AttrName". The preferences may also define an interfacer, as a java bean (see the apploader information) with the uri :setAttrName and the same bean for the renderer and editor with the uri :setConfigNameEditor. Without an interfacer, it uses the java name to find the javabeans methods 'getJname' and 'setJname'.

 :setAttrName
 		a lal:Bean ;
		rdfs:label "Function Object to Set an Attribute Name"@en ;
		lal:className "edu.umd.cfar.lamp.viper.gui.config.SetAttrName" .
 :attrConfigNameEditor
		a props:Editor ;
		lal:className "edu.umd.cfar.lamp.viper.gui.config.AttrNameEditor" ;
		lal:setProperty [ 
			lal:propertyName "Text" ] .
 

The setAttrName is a PropertyInterfacer, impelemnted by the class specified by lal:className. The label isn't used currently.
