Definition

JFace Data Binding is a multi-threaded set of abstractions that allow for automated validation and synchronization of values between objects. This is commonly used for, but not limited to, the binding of user interface components to model attributes. The core concepts behind the project are Observables and Bindings. We provide IObservable implementations for SWT, JFace, and JavaBeans but the core is void of references to these in anticipation of implementations for other projects (e.g. EMF, Swing, etc.).
