Method Detail

init

public void init(TransformParameterSpec params)
          throws InvalidAlgorithmParameterException

Description copied from class: TransformService

Initializes this TransformService with the specified parameters.

If the parameters exist in XML form, the TransformService.init(XMLStructure, XMLCryptoContext) method should be used to initialize the TransformService.

Specified by:

init in class TransformService

Parameters:

params - the algorithm parameters (may be null if not required or optional)

Throws:

InvalidAlgorithmParameterException - if the specified parameters are invalid for this algorithm

init

public void init(XMLStructure parent,
                 XMLCryptoContext context)
          throws InvalidAlgorithmParameterException

Description copied from class: TransformService

Initializes this TransformService with the specified parameters and document context.

Overrides:

init in class ApacheTransform

Parameters:

parent - a mechanism-specific structure containing the parent structure

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

Throws:

InvalidAlgorithmParameterException - if the specified parameters are invalid for this algorithm

marshalParams

public void marshalParams(XMLStructure parent,
                          XMLCryptoContext context)
                   throws MarshalException

Description copied from class: TransformService

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

Overrides:

marshalParams in class ApacheTransform

Parameters:

parent - a mechanism-specific structure containing the parent node that the marshalled parameters should be appended to

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

Throws:

MarshalException - if the parameters cannot be marshalled
