Examples of org.apache.tapestry5.plastic.FieldConduit

org.apache.tapestry5.services.ValidationMessagesSource
A {@link FieldConduit} is an object that effectively replaces the field in the instantiated object.All reads and writes of the field are replaced with invocations on the conduit. Once a field's access is replaced with a conduit, the field itself is no longer used. The conduit will even see initializations of the field.
In Aspect Oriented Programming terms, a FieldConduit allows you to advise read and write access to the field.
If a field has both a FieldConduit and a {@link FieldHandle}, then the methods of the FieldHandle will be connected to the methods of the FieldConduit.
