Method Detail

createKeyInfoData

public static KeyInfoData createKeyInfoData(org.w3c.dom.Element element)

Creates a new instance of the implementation class for the given Element, and uses it to wrap the Element. The namespace and tag name are taken from the given Element.

Parameters:

element - The element to be wrapped.

Returns:

An instance of a subclass of KeyInfoData; a GenericKeyInfo is returned if a corresponding implementation class cannot be identified.

createKeyInfoData

public static KeyInfoData createKeyInfoData(org.w3c.dom.Element element,
                                            java.lang.String systemId)

Creates a new instance of the implementation class for the given Element, and uses it to wrap the Element. The namespace and tag name are taken from the given Element.

Parameters:

element - The element to be wrapped.

systemId - The URI string system ID of the KeyInfoData.

Returns:

An instance of a subclass of KeyInfoData; a GenericKeyInfo is returned if a corresponding implementation class cannot be identified.

Since:

2.0
