  org.apache.myfaces.orchestra.dynaForm.metadata.impl.jsf.AbstractJsfExtractor

All Implemented Interfaces:

Extractor

Direct Known Subclasses:

JsfExclusiveExtractor, JsfExtractor

public abstract class AbstractJsfExtractor
extends Object
implements Extractor

Extract metadata from a DynaForm UIComponent.

This looks for child DynaConfig components attached to the DynaForm and merges any overrides they declare with the current values of a MetaData object. This allows basic information about an entity to be determined by other means, then for any components attached to the DynaForm component to override those settings.
