Example:

You may create a data binding expression via Binding { ??? } block annotation.

         val bindingInt: Binding[Int] = Binding { 100 }

A data binding expression may depend on other binding expressions via bind method:

         val bindingString: Binding[String] = Binding { bindingInt.bind.toString }

Attributes

Note:: This method is recursive, which means that the dependencies of this Binding will be unwatched as well.

Enable automatic recalculation.

You may invoke this method more than once. Then, when you want to disable automatic recalculation, you must invoke unwatch same times as the number of calls to this method.

Attributes

Note:: This method is recursive, which means that the dependencies of this Binding will be watched as well.

Inherited methods

Extension method from Binding

Returns the current value of this Binding and marks the current @dom method depend on this Binding.

Each time the value changes, in the current @dom method, all code after the current bind expression will be re-evaluated if the current @dom method is watching. However, code in current @dom method and before the current bind expression will not be re-evaluated. The above rule is not applied to DOM nodes created by XHTML literal. A bind expression under a DOM node does not affect siblings and parents of that node.

Attributes

Note:: This method must be invoked inside a @dom method body or a Binding { ... } block..
