Detailed Description

Class to read a DOM object from an XML file or an input stream.

This class produces a DOM object, which can be subsequently used to create a corresponding user object.

We do not recommend to directly use this class for user object reading, because the user has to handle both DOM object generation from the input XML file and user object generation from the intermediate DOM object. Users should derive from the DOMReader, because it performs the former step automatically and lets the users concentrate on the latter step, thus implementation of such a reader is simplified.

Note: Though this class behaves similar to ProcessObject, it is not derived from ProcessObject. This is because the output of this class, i.e. a DOMNode object, is not a DataObject, thus this class cannot be connected to an ITK process pipeline.

The following code snippet demonstrates how to read a DOM object from an XML file:

itk::DOMNode::Pointer output_dom_object;
const char* input_xml_file_name = ...
itk::DOMNodeXMLReader::Pointer reader = itk::DOMNodeXMLReader::New();
reader->SetFileName( input_xml_file_name );
reader->Update();
output_dom_object = reader->GetOutput();

Member Function Documentation

virtual void itk::DOMNodeXMLReader::CharacterDataHandler ( const char *  text, int  len  )

virtual

Callback function – called from XML parser with the character data for an XML element.

virtual::itk::LightObject::Pointer itk::DOMNodeXMLReader::CreateAnother ( void  ) const

virtual

Create an object from an instance, potentially deferring to a factory. This method allows you to create an instance of an object that is exactly the same type as the referring object. This is useful in cases where an object has been cast back to a base class.

Reimplemented from itk::Object.

virtual void itk::DOMNodeXMLReader::EndElement ( const char *  name )

virtual

Callback function – called from XML parser when ending tag encountered.

virtual const char* itk::DOMNodeXMLReader::GetFileName ( ) const

virtual

Get the input XML filename.

virtual const char* itk::DOMNodeXMLReader::GetNameOfClass ( ) const

virtual

Run-time type information (and related methods).

Reimplemented from itk::Object.

virtual OutputType* itk::DOMNodeXMLReader::GetOutput ( )

virtual

Get the output DOM object for full access.

virtual const OutputType* itk::DOMNodeXMLReader::GetOutput ( )

virtual

Get the output DOM object for read-only access.

static Pointer itk::DOMNodeXMLReader::New ( )

static

Method for creation through the object factory.

Referenced by operator>>().

void itk::DOMNodeXMLReader::operator= ( const Self &  )

private

virtual void itk::DOMNodeXMLReader::SetFileName ( const char *  _arg )

virtual

Set the input XML filename.

virtual void itk::DOMNodeXMLReader::SetOutput ( OutputType *  _arg )

virtual

The output DOM object will be created automatically, but the user can appoint a user DOM object as the output by calling this function.

virtual void itk::DOMNodeXMLReader::StartElement ( const char *  name, const char **  atts  )

virtual

Callback function – called from XML parser with start-of-element information.

void itk::DOMNodeXMLReader::Update

(

std::istream &

is

)

Function called by Update() or end-users to generate the output DOM object from an input stream such as file, string, etc.

virtual void itk::DOMNodeXMLReader::Update ( )

virtual

Function called by end-users to generate the output DOM object from the input XML file.

Member Data Documentation

OutputType* itk::DOMNodeXMLReader::m_Context

private

Variable to keep the current context during XML parsing.
