Interface HTMLFieldRenderer

All Superinterfaces:

HTMLRenderingContext

All Known Implementing Classes:

HTMLFieldRendererImpl

public interface HTMLFieldRenderer

extends HTMLRenderingContext

The HTMLFieldRenderer interface defines the set of functions to be implemented by a field renderer. If you are creating a field renderer for use in the oracle.jbo.html.databeans.EditCurrentRecord Data Web Bean, you can avoid implementing all of the methods by extending your field renderer class from the HTMLFieldRendererImpl class. The only method you need to override is populateForm().
