Constructor Detail

CanonicalizationAlgorithmImplCanonicalXML

public CanonicalizationAlgorithmImplCanonicalXML()

Standard constructor. Sets the default value for the algorithm URI to http://www.w3.org/TR/2001/REC-xml-c14n-20010315.

Method Detail

toElement

public org.w3c.dom.Element toElement(org.w3c.dom.Document signatureDOMDoc)
                              throws AlgorithmException

Returns the DOM element representation of the algorithm.

Specified by:

toElement in class Algorithm

Parameters:

signatureDOMDoc - The DOM document which should be used to create necessary DOM nodes.

Returns:

the DOM element representation of the algorithm.

Throws:

AlgorithmException - if no identifying URI has been specified for this algorithm.

canonicalize

public java.io.InputStream canonicalize()
                                 throws AlgorithmException

Creates a canonical physical representation of the specified XPath node set input according to the standard mentioned in the description of this class.

Specified by:

canonicalize in class CanonicalizationAlgorithm

Returns:

the canonical physical representation of this algorithm's input.

Throws:

AlgorithmException - if no input has been set previously, or if computing the canonical physical representation fails for any reason.
