Class PropertyLink

java.lang.Object
  org.progeeks.meta.util.PropertyLink

public class PropertyLink
extends java.lang.Object

Synchronizes a property on one object with a property on another. Objects are denoted as primary and secondary but the link works in both directions. The primary designation is used to define the initial value that should be pushed to the secondary. The secondary object is passive during initialization.

This object supports linking both meta-objects and beans. It will also auto-create links to beans created by a BeanConfigurator if the secondary of the link is a BeanConfigurator.

One example use for this class would be linking a user preferences object to factory created user interface components. In that case, the primary object would be the preferences object (potentially persisted or backed by Java preferences) and would be automatically linked to the UI beans created by the BeanConfigurator set as the secondary object.
