Constructor Detail

DHKeyValueImpl

public DHKeyValueImpl(DOMCryptoContext context,
                      Node node)
               throws MarshalException

Creates a new instance of this DHKeyValueImpl with the specified context and node to unmarshal from.

Parameters:

context - the context

node - the node to unmarshal from

Throws:

MarshalException - if an exception occurs during unmarshaling

DHKeyValueImpl

public DHKeyValueImpl(DHPublicKey dhPublicKey)

Creates a new instance of this DHKeyValueImpl with the specified DH public key.

Parameters:

dhPublicKey - the DH public key

Throws:

NullPointerException - if dhPublicKey is null

Method Detail

getLocalName

public String getLocalName()

Description copied from class: DOMStructure

Returns the local name of the represented XML element.

Specified by:

getLocalName in class DOMStructure

Returns:

the local name of the represented XML element

See Also:

DOMStructure.getLocalName()

marshal

public Node marshal(DOMCryptoContext context,
                    Node parent,
                    Node nextSibling)
             throws MarshalException

Description copied from class: DOMStructure

Marshal the DOM node representation of this DOMStructure and all its child DOMStructures.
This method calls

• DOMStructure.marshalElement(DOMCryptoContext, Node, Node)
• DOMStructure.marshalAttributes(DOMCryptoContext, Element)
• DOMStructure.marshalIDAttribute(DOMCryptoContext, Element)
• and DOMStructure.marshal(DOMCryptoContext, Node, Node) for every DOMStructure returned by DOMStructure.getChildStructures().

Overrides:

marshal in class DOMStructure

Parameters:

context - the DOMMarshalContext holding context information about the marshaling of this DOMStructure

parent - where to place the marshalled node

nextSibling - before wich to place the marshalled node

Returns:

the DOM node representation of this DOMStrucuture and all its child DOMStructurues

Throws:

MarshalException - if the marshaling fails for any reason

See Also:

DOMStructure.marshal(DOMCryptoContext, Node, Node)

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

See Also:

DOMStructure.unmarshalStructures(org.w3c.dom.NodeList, DOMCryptoContext)

getGenerator

public BigInteger getGenerator()

Returns:

Returns the generator.

getPGenCounter

public int getPGenCounter()

Returns:

Returns the pGenCounter.

getPrimeP

public BigInteger getPrimeP()

Returns:

Returns the primeP.

getPrimeQ

public BigInteger getPrimeQ()

Returns:

Returns the primeQ.

getPublicValue

public BigInteger getPublicValue()

Returns:

Returns the publicValue.

getSeed

public byte[] getSeed()

Returns:

Returns the seed.
