摘要： A system and method is disclosed for routing data of a declarative source expression to a destination. Declarative source expressions are analyzed at compile-time to discover variable properties. As such properties are discovered, a binding object is created and a list of watcher objects is generated associated with the particular variable properties. The watcher object includes a change event notification which is broadcast when a change in the property is detected. When a change event notification is received, a binding object, which is also automatically generated by the compiler, is executed causing the variable property to be read and the declarative source expression to be re-evaluated which propagates the property changes through the application.
