Method Detail

getIQChildElementBuilder

protected IQ.IQChildElementXmlStringBuilder getIQChildElementBuilder(IQ.IQChildElementXmlStringBuilder xml)

Description copied from class: IQ

This method must be overwritten by IQ subclasses to create their child content. It is important that the builder does not include the final end element. This will be done automatically by IQChildelementXmlStringBuilder after eventual existing stanza(/packet) extensions have been added.

For example to create an IQ with a extra attribute and an additional child element

 
 <iq to='foo@example.org' id='123'>
   <bar xmlns='example:bar' extraAttribute='blaz'>
      <extraElement>elementText</extraElement>
   </bar>
 </iq>
 
 

the body of the getIQChildElementBuilder looks like

 
 // The builder 'xml' will already have the child element and the 'xmlns' attribute added
 // So the current builder state is "<bar xmlns='example:bar'"
 xml.attribute("extraAttribute", "blaz");
 xml.rightAngleBracket();
 xml.element("extraElement", "elementText");
 // Do not close the 'bar' attribute by calling xml.closeElement('bar')
 
 

If your IQ only contains attributes and no child elements, i.e. it can be represented as empty element, then you can mark it as such.

 xml.attribute("myAttribute", "myAttributeValue");
 xml.setEmptyElement();
 

If your IQ does not contain any attributes or child elements (besides stanza(/packet) extensions), consider sub-classing SimpleIQ instead.

Specified by:

getIQChildElementBuilder in class IQ

Parameters:

xml - a pre-created builder which already has the child element and the 'xmlns' attribute set.

Returns:

the build to create the IQ child content.
