Class DefaultMetaForm

java.lang.Object
  org.progeeks.meta.view.DefaultMetaForm

All Implemented Interfaces:

MetaForm

public class DefaultMetaForm
extends java.lang.Object
implements MetaForm

Default implementation of MetaForm that works from a list of PropertyInfo objects. This is primarily to make subclasses easier to write and to provide an "identity" MetaForm implementation. Right now this MetaForm implementation is mutable so that it can be more easily configured. Still up in the air whether or not forms will be mutable in the long run so I'm not making this Fixable.
