Method Detail

getOutputDefinition

public OutputDefinition getOutputDefinition()

getDatatype

public Datatype getDatatype()

Specified by:

getDatatype in interface DataWidget

getId

public String getId()

Description copied from class: AbstractWidget

Gets the id of this widget.

Specified by:

getId in interface Widget

Overrides:

getId in class AbstractWidget

readFromRequest

public void readFromRequest(FormContext formContext)

Description copied from interface: Widget

Lets this widget read its data from a request. At this point the Widget may try to convert the request parameter to its native datatype (if it is not a string), but it should not yet generate any validation errors.

Specified by:

readFromRequest in interface Widget

validate

public boolean validate(FormContext formContext)

Description copied from interface: Widget

Validates this widget and returns the outcome. Possible error messages are remembered by the widget itself and will be part of the XML produced by this widget in its Widget.generateSaxFragment(ContentHandler, Locale) method.

Specified by:

validate in interface Widget

Overrides:

validate in class AbstractWidget

generateSaxFragment

public void generateSaxFragment(ContentHandler contentHandler,
                                Locale locale)
                         throws SAXException

Description copied from interface: Widget

Generates an XML representation of this widget. The startDocument and endDocument SAX events will not be called. It is assumed that the prefix for the Woody namespace mentioned in Constants.WI_PREFIX is already declared (by the caller or otherwise).

Specified by:

generateSaxFragment in interface Widget

Throws:

SAXException

generateLabel

public void generateLabel(ContentHandler contentHandler)
                   throws SAXException

Description copied from interface: Widget

Generates SAX events for the label of this widget. The label will not be wrapped inside another element.

Specified by:

generateLabel in interface Widget

Overrides:

generateLabel in class AbstractWidget

Throws:

SAXException

getValue

public Object getValue()

Description copied from interface: Widget

Returns the value of the widget. For some widgets (notably ContainerWidgets) this may not make sense, those should then simply return null here.

Specified by:

getValue in interface Widget

Overrides:

getValue in class AbstractWidget

setValue

public void setValue(Object object)

Description copied from interface: Widget

Sets the value of this widget to the given object. Some widgets may not support this method, those should throw an runtime exception if you try to set their value anyway.

Specified by:

setValue in interface Widget

Overrides:

setValue in class AbstractWidget
