Constructor Detail

CipherDataImpl

public CipherDataImpl(DOMCryptoContext context,
                      Node node)
               throws MarshalException

Creates a new instance of this CipherDataImpl 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

CipherDataImpl

public CipherDataImpl(CipherReferenceImpl cipherReference)

Creates a new instance of this CipherDataImpl with the specified cipher reference.

Parameters:

cipherReference - the cipher reference

Throws:

NullPointerException - if cipherData is null

CipherDataImpl

public CipherDataImpl(CipherValueImpl cipherValue)

Creates a new instance of this CipherDataImpl with the specified cipher data.

Parameters:

cipherValue - the cipher data

Throws:

NullPointerException - if cipherData 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()

getCipherData

public CipherData getCipherData()

Returns the cipher data.

Returns:

the cipher data

getCipherText

public InputStream getCipherText()

Returns the encrypted data if this CipherData stores the encrypted data as CipherReference.

Returns:

the encrypted data if this CipherData has CipherReference as CipherData

Throws:

IllegalStateException - if a CipherData is not a CipherReference; or this method is called on a unmarshalled EncryptedType.

setCipherText

public void setCipherText(byte[] value)

Sets the cipher value of this CipherData.

Parameters:

value - the cipher value

getCipherData

public InputStream getCipherData(XMLDecryptContext context)
                          throws XMLEncryptionException

Gets the cipher data form this CipherData.

Parameters:

context - the context

Returns:

the cipher value input stream

Throws:

XMLEncryptionException - if an unexpected exception occurs during dereferencing the CipherReference

getChildStructures

protected List getChildStructures()

Description copied from class: DOMStructure

Returns the list of child structures of this DOMStructure.

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

A subclass has to overwrite this method to return a list of DOMStrucutres represented by this subclass.

Overrides:

getChildStructures in class DOMStructure

Returns:

a list of DOMStructures (may be empty, but never null)

See Also:

DOMStructure.getChildStructures()

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

See Also:

DOMStructure.putChildStructure(iaik.xml.crypto.dom.DOMStructure)
