Constructor Details

KeyDerivationMethodImpl

public KeyDerivationMethodImpl(Document doc)

Constructor KeyDerivationMethodImpl creates a new KeyDerivationMethodImpl instance.

Parameters:

doc - the Document in which to create the DOM tree

KeyDerivationMethodImpl

public KeyDerivationMethodImpl(Element element,
 String baseURI)
                        throws XMLSecurityException

Constructor KeyDerivationMethodImpl from existing XML element.

Parameters:

element - the element to use as source

baseURI - the URI of the resource where the XML instance was stored

Throws:

XMLSecurityException - if a parsing error occurs

Method Details

setAlgorithm

public void setAlgorithm(String algorithm)

Sets the Algorithm attribute.

Parameters:

algorithm - URI

getAlgorithm

public String getAlgorithm()

Description copied from interface: KeyDerivationMethod

Returns the algorithm URI of this KeyDerivationMethod.

Specified by:

getAlgorithm in interface KeyDerivationMethod

Returns:

the algorithm URI string

getKDFParams

public KDFParams getKDFParams()
                       throws XMLSecurityException

Method returns the KDFParams object of this KeyDerivationMethod Element. If the KDFParams object is not set/cached, it tries to parse it (and cache it) from the KeyDerivationMethod Element. If the KDFParams cannot be parsed/or the Key derivation function URI is not supported, an XMLSecurityException is thrown.

Specified by:

getKDFParams in interface KeyDerivationMethod

Returns:

the Key derivation function parameters.

Throws:

XMLSecurityException - if the KDFParams cannot be created or the KDF URI is not supported.

setKDFParams

public void setKDFParams(KDFParams kdfParams)

getBaseLocalName

public String getBaseLocalName()

Description copied from class: ElementProxy

Returns the localname of the Elements of the sub-class.

Specified by:

getBaseLocalName in class ElementProxy

Returns:

the localname of the Elements of the sub-class.

toString

public String toString()

Overrides:

toString in class Object
