Constructor Detail

CipherValueImpl

public CipherValueImpl(DOMCryptoContext context,
                       Node node)
                throws MarshalException

Creates a new instance of this CipherValueImpl 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

CipherValueImpl

public CipherValueImpl()

Creates a new instance of this CipherValueImpl.

CipherValueImpl

public CipherValueImpl(InputStream cipherValueStream)

Creates a new instance of this CipherValueImpl with the specified input stream providing the cipher value.

Parameters:

cipherValueStream - the input stream providing the cipher value

Throws:

NullPointerException - if cipherValueStream is null

IllegalArgumentException - if cipherValueStream cannot be read from

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()

getValue

public byte[] getValue()

Description copied from interface: javax.xml.crypto.enc.CipherValue

Returns the encrypted data. Each invocation of this method returns a clone of the data, to protect against subsequent modification.

Specified by:

getValue in interface CipherValue

Returns:

the encrypted data

See Also:

CipherValue.getValue()

setValue

public void setValue(byte[] value)

Sets the value of this CipherValue.

Parameters:

value - the cipher value

getValueStream

public InputStream getValueStream()

Returns the raw value as InputStream.

Returns:

the raw value as InputStream, or null if no value is present.

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)

unmarshalElement

protected void unmarshalElement(DOMCryptoContext context,
                                Element element)
                         throws MarshalException

Description copied from class: DOMStructure

Unmarshals the given element.

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

A subclass has to overwrite this method to perform any special unmarshaling required.

Overrides:

unmarshalElement in class DOMStructure

Parameters:

context - the marshal context

element - the element to be unmarshal

Throws:

MarshalException - if an exception occurs during unmarshaling

See Also:

DOMStructure.unmarshalElement(javax.xml.crypto.dom.DOMCryptoContext, org.w3c.dom.Element)

appendValue

public void appendValue(DOMCryptoContext context,
                        byte[] value)
                 throws MarshalException

Appends the given cipher value.

Parameters:

context - the context

value - the raw cipher value

Throws:

MarshalException - if an exception occurs during marshaling
