the DigestMethod

getMGF

public String getMGF()

Returns the MGF.

Returns:

the MGF

getMGFDigestMethod

public DigestMethod getMGFDigestMethod()

Returns the DigestMethod used for the MGF.

marshalElement

protected Element marshalElement(DOMCryptoContext context,
                                 Node parent,
                                 Node nextSibling)
                          throws MarshalException

Description copied from class: DOMStructure

Marshals the XML representation of the Element represented by this DOMStructure and returns it.

This method is called by DOMStructure.marshal(DOMCryptoContext, Node, Node).

Overrides:

marshalElement in class DOMStructure

Parameters:

context - the marshal context

parent - where to place the marshalled element

nextSibling - before which to place the marshalled node

Returns:

the marshaled Element

Throws:

MarshalException - if an exception occurs during marshaling

See Also:

DOMStructure.marshalElement(DOMCryptoContext, Node, Node)

putChildStructure

protected void putChildStructure(DOMStructure childStructure)
                          throws MarshalException

Description copied from class: DOMStructure

Put an unmarshalled child structure.

This method is called by DOMStructure.unmarshalStructures(NodeList, DOMCryptoContext) for every unmarshalled child structure.

A subclass has to overwrite this method to store the given child structure in its the corresponding field.

Overrides:

putChildStructure in class DOMStructure

Parameters:

childStructure - the unmarshalled child structure

Throws:

MarshalException

unmarshalStructures

protected void unmarshalStructures(NodeList nodes,
                                   DOMCryptoContext context)
                            throws MarshalException

Description copied from class: DOMStructure

Unmarshals DOMStructures from the given nodes.

This method is called by DOMStructure.unmarshal(DOMCryptoContext).

This method calls DOMStructure.getInstance(Node, DOMCryptoContext) for every Element in the list of nodes. If DOMStructure.getInstance(Node, DOMCryptoContext) returns a DOMStructure DOMStructure.putChildStructure(DOMStructure) is called with the returned DOMStructure as parameter.

Overrides:

unmarshalStructures in class DOMStructure

Parameters:

nodes - the nodes to unmarshal from

context - the marshal context

Throws:

MarshalException - if an exception occurs during marshaling
