Examples of org.apache.axiom.om.OMDataSourceExt

org.apache.axiom.om.OMDataSourceExt
Interface to a backing object that can can be read and written as XML. To plug an arbitrary object into an OM tree. Follow these steps 1) Provide a class that implements OMDataSourceExt. 2) Use OMFactory.createOMElement(OMDataSource, String, OMNamespace) to build an OMSourcedElement. 3) Add the OMSourcedElement to the OM tree. OMDataSourceExt provides additional methods that are not available on the original OMDataSource. @see OMDataSource @see OMSourceElementImpl
