# Class UiBinding.Binding

java.lang.Object
com.codename1.properties.UiBinding.Binding

Enclosing class:
  `UiBinding`

public abstract class UiBinding.Binding extends Object

Binding allows us to have commit/auto-commit mode. This allows changes to properties to reflect immediately or only when committed, e.g. if a `Form` has "OK" & "Cancel" buttons you might want to do a commit on OK. We also provide a "rollback" method to reset to the original property values.

`UiBinding` has a boolean auto commit flag that can be toggled to set the default for new bindings.

Binding also provides the ability to disengage a "binding" between a property and a UI component
