Class Transform

java.lang.Object

weblogic.xml.security.transforms.Transform

All Implemented Interfaces:

DSIGConstants

public abstract class Transform
extends Object
implements DSIGConstants

Represents a transformation to be applied to data before applying a cryptographic operation such as digesting. A Transform consists of an Algorithm attribute and a set of parameters, if any, appropriate for the given algorithm.

Method Detail

getTransform

public static Transform getTransform(String uri)
                              throws TransformException

Throws:

TransformException

getURI

public abstract String getURI()

Returns:

The URI for the Transform

setParameter

public void setParameter(String name,
                         String value)
                  throws TransformException

Sets a parameter for the Transform. For example, this may be used to set the XPath expression for an XPath Transform

Throws:

TransformException

setNamespaces

public abstract void setNamespaces(Map namespaceMap)

setNamespaces allows the caller to pass in a set of namespaces in the scope of but not declared in the node/data being transformed. This allows the c14n algorith to fill in the missing pieces.

Parameters:

namespaceMap - a Map value

getXMLOutputStream

public abstract XMLOutputStream getXMLOutputStream()
                                            throws XMLStreamException

Throws:

XMLStreamException

setDest

public final void setDest(Transform dest)
                   throws IncompatibleTransformException

Allows Transforms to be chained.

Throws:

IncompatibleTransformException

toXML

public void toXML(XMLOutputStream xos,
                  String ns,
                  int indent)
           throws XMLStreamException

Throws:

XMLStreamException

toXMLInternal

protected void toXMLInternal(XMLOutputStream xos,
                             String ns,
                             int indent)
                      throws XMLStreamException

Throws:

XMLStreamException

fromXMLInternal

protected void fromXMLInternal(XMLInputStream xin,
                               String ns)
                        throws XMLStreamException

Throws:

XMLStreamException

main

public static void main(String[] args)
                 throws Exception

Throws:

Exception
