Constructor Detail

C14NTransform

public C14NTransform()

Creates a new C14NTransform instance.

C14NTransform

public C14NTransform(XSAlgorithmIdentifier trans)

Creates a new C14NTransform instance.

Parameters:

trans - A XSAlgorithmIdentifier object containing no parameter element.

Throws:

java.lang.IllegalArgumentException - If the XSAlgorithmIdentifier is not a valid XML-C14N Transform.

Method Detail

getAlgorithmURI

public java.lang.String getAlgorithmURI()

Description copied from class: XSTransformer

Returns the URI string identifying the Transform algorithm.

Specified by:

getAlgorithmURI in class XSTransformer

Returns:

This Transform's URI string.

transform

public XMLContainer transform(XMLContainer source)
                       throws TransformationException

Applies the Canonical XML transformation to the given XMLContainer and returns the octet stream result a new XMLContainer.

Specified by:

transform in class XSTransformer

Parameters:

source - A XMLContainer on which the transform will operate.

Returns:

A XMLContainer containing the transform octet stream result.

Throws:

TransformationException - if an error occurs during the transformation process.

transformToStream

public java.io.InputStream transformToStream(NodeReader source)
                                      throws TransformationException

Description copied from interface: NodeToStreamTransform

transform method that does not actually do the transform, but only sets up things. The actual transform should be done when somebody reads from the InputStream

Specified by:

transformToStream in interface NodeToStreamTransform

Returns:

Throws:

TransformationException
