Returns the algorithm-specific input parameters associated with this Transform.

The returned parameters can be typecast to a TransformParameterSpec object.

Implements abstract javax.xml.crypto.dsig.TransformService.marshalParams.

Doc from javax.xml.crypto.dsig.TransformService.marshalParams.

Marshals the algorithm-specific parameters. If there are no parameters to be marshalled, this method returns without throwing an exception.

Annotations
@Override
Exceptions
MarshalException:

transformback to summary
public Data transform(Data data, XMLCryptoContext xc, OutputStream os) throws TransformException

Implements javax.xml.crypto.dsig.Transform.transform.

Doc from javax.xml.crypto.dsig.Transform.transform.

Transforms the specified data using the underlying transform algorithm. If the output of this transform is an OctetStreamData, then this method returns null and the bytes are written to the specified OutputStream. Otherwise, the OutputStream is ignored and the method behaves as if transform(Data, XMLCryptoContext) were invoked.

Annotations
@Override
Exceptions
TransformException:
if an error occurs while executing the transform
