Class BindingProxy

java.lang.Object

groovy.lang.GroovyObjectSupport

org.codehaus.groovy.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 bininfs Formerly Known as Model Binding.

Since:

Groovy 1.5

Description copied from interface: BindingUpdatable

Causes the current bindings to be reset. If the binding is not bound, it is a no-op. If the binding is bound, it will be turned off, then turned on against current values.

Specified by:

rebind in interface BindingUpdatable

update

public void update()

Description copied from interface: BindingUpdatable

Causes the values to be propagated from the source to the target
