public interface RetrievalMethod extends URIReference, XMLStructure
RetrievalMethod
element as defined in the W3C Recommendation for XML-Signature Syntax and Processing. A RetrievalMethod
object is used to convey a reference to KeyInfo
information that is stored at another location. The XML schema definition is defined as: <element name="RetrievalMethod" type="ds:RetrievalMethodType"/> <complexType name="RetrievalMethodType"> <sequence> <element name="Transforms" type="ds:TransformsType" minOccurs="0"/> </sequence> <attribute name="URI" type="anyURI"/> <attribute name="Type" type="anyURI" use="optional"/> </complexType>A
RetrievalMethod
instance may be created by invoking one of the newRetrievalMethod
methods of the KeyInfoFactory
class, and passing it the URI identifying the location of the KeyInfo, an optional type URI identifying the type of KeyInfo, and an optional list of Transform
s; for example: KeyInfoFactory factory = KeyInfoFactory.getInstance("DOM"); RetrievalMethod rm = factory.newRetrievalMethod ("#KeyValue-1", KeyValue.DSA_TYPE, Collections.singletonList(Transform.BASE64));

and applies the specified Transform
s.context
- an XMLCryptoContext
that may contain additional useful information for dereferencing the URI. The context's baseURI
and dereferencer
parameters (if specified) are used to resolve and dereference this RetrievalMethod

object representing the raw contents of the KeyInfo
information referenced by this RetrievalMethod
. It is the caller's responsibility to convert the returned data to an appropriate KeyInfo
object.NullPointerException

is null
