      extended by org.xmpp.forms.DataForm

public class DataForm
extends PacketExtension

Represents a form that could be use for gathering data as well as for reporting data returned from a search.

The form could be of the following types:

In case the form represents a search, the report will be structured in columns and rows. Use addReportedField(String,String,FormField.Type) to set the columns of the report whilst the report's rows can be configured using addItemFields(Map).
