public interface ModelData

Primary interface for GXT model objects without support events. Models support a form of "introspection" as property names and values can be retrieved at runtime.

For models with event support see Model.

For a default implementation see BaseModelData.

java.util.Collection<java.lang.String>	getPropertyNames() Returns an collection of the model's property names.
<X> X	remove(java.lang.String property) Removes the named property from this model instance.
<X> X	set(java.lang.String property, X value) Sets a property.
