Constructor Detail

DOMKeyInfo

public DOMKeyInfo(List<? extends XMLStructure> content,
                  String id)

Creates a DOMKeyInfo.

Parameters:

content - a list of one or more XMLStructures representing key information types. The list is defensively copied to protect against subsequent modification.

id - an ID attribute

Throws:

NullPointerException - if content is null

IllegalArgumentException - if content is empty

ClassCastException - if content contains any entries that are not of type XMLStructure

DOMKeyInfo

public DOMKeyInfo(Element kiElem,
                  XMLCryptoContext context,
                  Provider provider)
           throws MarshalException

Creates a DOMKeyInfo from XML.

Parameters:

kiElem - KeyInfo element

Throws:

MarshalException

Method Detail

getId

public String getId()

Description copied from interface: KeyInfo

Return the optional Id attribute of this KeyInfo, which may be useful for referencing this KeyInfo from other XML structures.

Specified by:

getId in interface KeyInfo

Returns:

the Id attribute of this KeyInfo (may be null if not specified)

getContent

public List getContent()

Description copied from interface: KeyInfo

Returns an unmodifiable list containing the key information. Each entry of the list is an XMLStructure.

If there is a public subclass representing the type of XMLStructure, it is returned as an instance of that class (ex: an X509Data element would be returned as an instance of X509Data).

Specified by:

getContent in interface KeyInfo

Returns:

an unmodifiable list of one or more XMLStructures in this KeyInfo. Never returns null or an empty list.

marshal

public void marshal(XMLStructure parent,
                    XMLCryptoContext context)
             throws MarshalException

Description copied from interface: KeyInfo

Marshals the key info to XML.

Specified by:

marshal in interface KeyInfo

Parameters:

parent - a mechanism-specific structure containing the parent node that the marshalled key info will be appended to

context - the XMLCryptoContext containing additional context (may be null if not applicable)

Throws:

MarshalException - if the key info cannot be marshalled

marshal

public void marshal(Node parent,
                    String dsPrefix,
                    DOMCryptoContext context)
             throws MarshalException

Specified by:

marshal in class DOMStructure

Throws:

MarshalException

marshal

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

Throws:

MarshalException

equals

public boolean equals(Object o)

Overrides:

equals in class Object

hashCode

public int hashCode()

Overrides:

hashCode in class Object
