#include <itkDOMReader.h>
Class to read an ITK object from an XML file or a DOM object, using the DOM APIs.
End-users need to derive from this class to implement readers for user objects. In subclasses, users need to provide an implementation for the virtual functions GenerateData(-,-).
This class performs similar functions as the XMLReader - both provide the base for handling object reading from an XML source. The difference is that, readers derived from this class perform object reading using the easy-to-use DOM APIs, while XMLReader-based readers use the more error-prone SAX (Simple API for XML) APIs.
Internally, this class first implicitly creates an intermediate DOM object from the input XML file using the DOMNodeXMLReader, then performs output object generation by pulling information from the DOM object.
Note: Though this class behaves similar to ProcessObject, it is not derived from ProcessObject. This is because many user objects to be read, e.g., registrations, transforms, optimizers, and so on, are not objects of type DataObject, thus this class cannot be connected to an ITK process pipeline.
The following code snippet demonstrates how to use a DOM-based reader that is derived from this class:

|
protectedpure virtual |
Function to be implemented in subclasses. It is called automatically when update functions are performed. It should fill the contents of the output object by pulling information from the intermediate DOM object. Some derived readers may accept an incomplete DOM object during the reading process, in those cases the optional argument 'userdata' can be used to provide the missed information.
