FAQ for the FRB Transition

How do I observe a path from my object for changes after they've happened?

Before

myObject.addPropertyChangeListener("path", handler)

When the path changes myObject.handleChange(notification) will be called

After

myObject.addPathChangeListener("path", handler)

When the path changes the handler function is called using the following strategy: When handler is a:

• function: function is called
• object: myObject.handlePathChange is called
• methodName: ```myObject[methodName] is called

and is passed the newValue, affectedPath, sourceObject

How do I observe a path from my object for changes before they happen?

Before

myObject.addPropertyChangeListener("path", handler, true)

After

myObject.addPathChangeListener("path", handler, "handleMethodName", true)

How do I bind a property of my object to a property of another object such that they are always the same?

Before

Object.defineBinding(myObject, "myProperty", {
    boundObject: anotherObject,
    boundObjectPropertyPath: "foo.bar"
});

After

myObject.defineBinding("myProperty", {"<->": "foo.bar", source: anotherObject});

How do I bind a property of my object to a property of another object such that changes to myProperty do not affect the otherObject's property?

Before

Object.defineBinding(myObject, "myProperty", {
    boundObject: anotherObject,
    boundObjectPropertyPath: "foo.bar",
    oneway: true
});

After

myObject.defineBinding("myProperty", {"<-": "foo.bar", source: anotherObject});
