Detailed Description

The base class for transforms.

The DSIGTransform class is the base class used to hold <Transform> elements within a document.

It does not in actually perform any transformations - only hold the information about a transform in a <Signature> structure.

Constructor & Destructor Documentation

DSIGTransform::DSIGTransform (  const XSECEnv *  env, XERCES_CPP_NAMESPACE_QUALIFIER DOMNode *  node )  [inline]

Contructor used for existing XML signatures. The Node structure already exists, so this type of Transform constructor will generally read the nodes in. Note: DSIGTransform structures should only ever be created via calls to a DSIGTransformList object. Parameters: env  The environment in which this transform operates node  The DOM node (within doc) that is to be used as the base of the Transform. See also: load

DSIGTransform::DSIGTransform (  const XSECEnv *  env  )  [inline]

Contructor used for new signatures. The Node structure will have to be created by the implementation class Note: DSIGTransform structures should only ever be created via calls to a DSIGTransformList object. Parameters: env  The environment descriptor for the object

virtual DSIGTransform::~DSIGTransform (   )  [inline, virtual]

Destructor. Destroy the DSIGSignature elements. Does not destroy any associated DOM Nodes

Member Function Documentation

virtual void DSIGTransform::appendTransformer (  TXFMChain *  input  )  [pure virtual]

Create the transformer element and append to an existing Chain. Implemented by each Transform class and used by the DSIGSignature to construct a complete Transform chain (TXFMChain). Implemented in DSIGTransformBase64, DSIGTransformC14n, DSIGTransformEnvelope, DSIGTransformXPath, DSIGTransformXPathFilter, and DSIGTransformXSL.

virtual XERCES_CPP_NAMESPACE_QUALIFIER DOMElement* DSIGTransform::createBlankTransform (  XERCES_CPP_NAMESPACE_QUALIFIER DOMDocument *  parentDoc  )  [pure virtual]

Construct a new transform. Instruct the implementation to create the required transform and return the newly constructed DOMNode structure Implemented in DSIGTransformBase64, DSIGTransformC14n, DSIGTransformEnvelope, DSIGTransformXPath, DSIGTransformXPathFilter, and DSIGTransformXSL.

XERCES_CPP_NAMESPACE_QUALIFIER DOMElement* DSIGTransform::createTransformNode (   )  [protected]

Create the basic node structure of a transform.

virtual transformType DSIGTransform::getTransformType (   )  [pure virtual]

Determine the transform type. Used to determine what the type of the transform is. Implemented in DSIGTransformBase64, DSIGTransformC14n, DSIGTransformEnvelope, DSIGTransformXPath, DSIGTransformXPathFilter, and DSIGTransformXSL.

virtual void DSIGTransform::load (  void   )  [pure virtual]

Load a DOM structure. Take the original node and load any sub nodes in the transform (if necessary) Implemented in DSIGTransformBase64, DSIGTransformC14n, DSIGTransformEnvelope, DSIGTransformXPath, DSIGTransformXPathFilter, and DSIGTransformXSL.
