Class PropertyValue

java.lang.Object
  de.ralfebert.rcputils.properties.PropertyValue

All Implemented Interfaces:

IValue

public class PropertyValue
extends java.lang.Object
implements IValue

PropertyValue: Resolves nested property Strings like "company.country.name". Use like this:

 PropertyValue prop = new PropertyValue("country.name");
 Object countryName = prop.getValue(someObject);
 

This class allows to use JFace Data Binding property support to get and set nested property values without observing them. Please note that this class is not prepared for a case where the classes of the objects change on the path to the property. For example, if you use "country.name" on a "Company" object once, it expects a "Company" object you use it the next time. WARNING: This uses internal data binding classes. This enhancement described in https://bugs.eclipse.org/bugs/show_bug.cgi?id=285307 would allow to use official API instead of this class.
