Class BindingProxy

java.lang.Object
groovy.lang.GroovyObjectSupport
org.apache.groovy.swing.binding.BindingProxy
All Implemented Interfaces:
GroovyObject, BindingUpdatable
public class BindingProxy extends GroovyObjectSupport implements BindingUpdatable
This class returns half bound FullBindings on the source half to the model object for every property reference (and I do mean every, valid or not, queried before or not). These returned half bindings are stored strongly in a list when generated. Changing the model will keep all existing bindings but change the source on all of the bindings. Formerly Known as Model Binding.
Since:
Groovy 1.5
