Method Detail

service

public void service(ServiceManager manager)
             throws ServiceException

Specified by:

service in interface Serviceable

Throws:

ServiceException

getDatatype

public Datatype getDatatype()

setDatatype

public void setDatatype(Datatype datatype)

setSelectionList

public void setSelectionList(SelectionList selectionList)

getSelectionList

public SelectionList getSelectionList()

buildSelectionList

public SelectionList buildSelectionList(String uri)

Builds a dynamic selection list from a source. This is a helper method for widget instances whose selection list source has to be changed dynamically, and it does not modify this definition's selection list, if any.

Parameters:

uri - The URI of the source.

buildSelectionListFromModel

public SelectionList buildSelectionListFromModel(Object model,
                                                 String valuePath,
                                                 String labelPath)

Builds a dynamic selection list from an in-memory collection. This is a helper method for widget instances whose selection list has to be changed dynamically, and it does not modify this definition's selection list, if any.

Parameters:

model - The collection used as a model for the selection list.

valuePath - An XPath expression referring to the attribute used to populate the values of the list's items.

labelPath - An XPath expression referring to the attribute used to populate the labels of the list's items.
