Method Detail

engineCanonicalizeXPathNodeSet

public byte[] engineCanonicalizeXPathNodeSet(Set<Node> xpathNodeSet,
                                             String inclusiveNamespaces)
                                      throws CanonicalizationException

Always throws a CanonicalizationException because this is inclusive c14n.

Specified by:

engineCanonicalizeXPathNodeSet in class CanonicalizerSpi

Parameters:

xpathNodeSet -

inclusiveNamespaces -

Returns:

none it always fails

Throws:

CanonicalizationException - always

engineCanonicalizeSubTree

public byte[] engineCanonicalizeSubTree(Node rootNode,
                                        String inclusiveNamespaces)
                                 throws CanonicalizationException

Always throws a CanonicalizationException because this is inclusive c14n.

Specified by:

engineCanonicalizeSubTree in class CanonicalizerSpi

Parameters:

rootNode -

inclusiveNamespaces -

Returns:

none it always fails

Throws:

CanonicalizationException

engineCanonicalizeSubTree

public byte[] engineCanonicalizeSubTree(Node rootNode,
                                        String inclusiveNamespaces,
                                        boolean propagateDefaultNamespace)
                                 throws CanonicalizationException

Always throws a CanonicalizationException because this is inclusive c14n.

Specified by:

engineCanonicalizeSubTree in class CanonicalizerSpi

Parameters:

rootNode -

inclusiveNamespaces -

propagateDefaultNamespace - If true the default namespace will be propagated to the c14n-ized root element

Returns:

none it always fails

Throws:

CanonicalizationException

handleAttributesSubtree

protected Iterator<Attr> handleAttributesSubtree(Element element,
                                                 NameSpaceSymbTable ns)
                                          throws CanonicalizationException

Returns the Attr[]s to be output for the given element.
The code of this method is a copy of handleAttributes(Element, NameSpaceSymbTable), whereas it takes into account that subtree-c14n is -- well -- subtree-based. So if the element in question isRoot of c14n, it's parent is not in the node set, as well as all other ancestors.

Parameters:

element -

ns -

Returns:

the Attr[]s to be output

Throws:

CanonicalizationException

handleAttributes

protected Iterator<Attr> handleAttributes(Element element,
                                          NameSpaceSymbTable ns)
                                   throws CanonicalizationException

Returns the Attr[]s to be output for the given element.
IMPORTANT: This method expects to work on a modified DOM tree, i.e. a DOM which has been prepared using XMLUtils.circumventBug2650( org.w3c.dom.Document).

Parameters:

element -

ns -

Returns:

the Attr[]s to be output

Throws:

CanonicalizationException

circumventBugIfNeeded

protected void circumventBugIfNeeded(XMLSignatureInput input)
                              throws CanonicalizationException,
                                     ParserConfigurationException,
                                     IOException,
                                     SAXException

Throws:

CanonicalizationException

ParserConfigurationException

IOException

SAXException

handleParent

protected void handleParent(Element e,
                            NameSpaceSymbTable ns)

Overrides:

handleParent in class CanonicalizerBase
