Class ValidateElement

java.lang.Object

org.jivesoftware.smackx.xdatavalidation.packet.ValidateElement

All Implemented Interfaces:

Element, FullyQualifiedElement, NamedElement, XmlLangElement, FormFieldChildElement

Direct Known Subclasses:

ValidateElement.BasicValidateElement, ValidateElement.OpenValidateElement, ValidateElement.RangeValidateElement, ValidateElement.RegexValidateElement

public abstract class ValidateElement
extends java.lang.Object
implements FormFieldChildElement

DataValidation Extension according to XEP-0122: Data Forms Validation. This specification defines a backwards-compatible extension to the XMPP Data Forms protocol that enables applications to specify additional validation guidelines related to a FormField in a DataForm, such as validation of standard XML datatypes, application-specific datatypes, value ranges, and regular expressions.

Nested Class Summary

Nested Classes

Modifier and Type	Class	Description
static class	ValidateElement.BasicValidateElement	Validation only against the datatype itself.
static class	ValidateElement.ListRange	This element indicates for "list-multi", that a minimum and maximum number of options should be selected and/or entered.
static class	ValidateElement.OpenValidateElement	For "list-single" or "list-multi", indicates that the user may enter a custom value (matching the datatype constraints) or choose from the predefined values.
static class	ValidateElement.RangeValidateElement	Indicate that the value should fall within a certain range.
static class	ValidateElement.RegexValidateElement	Indicates that the value should be restricted to a regular expression.
