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 will be called

After

myObject.addPathChangeListener("path", handler)

When the path changes myObject.handlePathChange will be called

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?

    boundObject: anotherObject,
    boundObjectPropertyPath: "foo.bar",
    oneway: true
});

After

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