Constructor Detail

DOMTransform

public DOMTransform(javax.xml.crypto.dsig.TransformService spi)

Creates a DOMTransform.

Parameters:

spi - the TransformService

DOMTransform

public DOMTransform(org.w3c.dom.Element transElem,
                    javax.xml.crypto.XMLCryptoContext context,
                    java.security.Provider provider)
             throws javax.xml.crypto.MarshalException

Creates a DOMTransform from an element. This constructor invokes the abstract unmarshalParams method to unmarshal any algorithm-specific input parameters.

Parameters:

transElem - a Transform element

Throws:

javax.xml.crypto.MarshalException

Method Detail

getParameterSpec

public final java.security.spec.AlgorithmParameterSpec getParameterSpec()

Specified by:

getParameterSpec in interface javax.xml.crypto.AlgorithmMethod

Specified by:

getParameterSpec in interface javax.xml.crypto.dsig.Transform

getAlgorithm

public final java.lang.String getAlgorithm()

Specified by:

getAlgorithm in interface javax.xml.crypto.AlgorithmMethod

marshal

public void marshal(org.w3c.dom.Node parent,
                    java.lang.String dsPrefix,
                    javax.xml.crypto.dom.DOMCryptoContext context)
             throws javax.xml.crypto.MarshalException

This method invokes the abstract marshalParams method to marshal any algorithm-specific parameters.

Specified by:

marshal in class DOMStructure

Throws:

javax.xml.crypto.MarshalException

transform

public javax.xml.crypto.Data transform(javax.xml.crypto.Data data,
                                       javax.xml.crypto.XMLCryptoContext xc)
                                throws javax.xml.crypto.dsig.TransformException

Transforms the specified data using the underlying transform algorithm.

Specified by:

transform in interface javax.xml.crypto.dsig.Transform

Parameters:

data - the data to be transformed

xc - the XMLCryptoContext containing additional context (may be null if not applicable)

Returns:

the transformed data

Throws:

java.lang.NullPointerException - if data is null

javax.xml.crypto.dsig.XMLSignatureException - if an unexpected error occurs while executing the transform

javax.xml.crypto.dsig.TransformException

transform
