Detailed Description

template<typename TInput>
class itk::DOMWriter< TInput >

Class to write an ITK object to an XML file or a DOM object, using the DOM APIs.

End-users need to derive from this class to implement writers for user objects. In subclasses, users need to provide an implementation for the virtual function GenerateData(-,-).

This class performs similar functions as the XMLWriterBase - both provide the base for handling object writing to an XML destination. The difference is that, writers derived from this class perform object writing using the easy-to-use DOM APIs, while XMLWriterBase-based writers directly generate textual XML documents, which is tedious and more error prone.

Internally, this class first generates an intermediate DOM object from the input object, then the DOM object is implicitly written to the output XML file using the DOMNodeXMLWriter.

Note: Though this class behaves similar to ProcessObject, it is not derived from ProcessObject. This is because many user objects to be written, 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 writer that is derived from this class:

itk::MyObjectType::Pointer input_object = ...
const char* output_xml_file_name = ...
auto writer = itk::MyObjectDOMWriter::New();
writer->SetInput( input_object );
writer->SetFileName( output_xml_file_name );
writer->Update();
