Method Detail

getTransforms

public java.util.List getTransforms()

Description copied from interface: RetrievalMethod

Returns an unmodifiable list of Transforms of this RetrievalMethod.

Specified by:

getTransforms in interface RetrievalMethod

Returns:

an unmodifiable list of Transform objects (may be empty but never null).

dereference

public Data dereference(XMLCryptoContext context)
                 throws URIReferenceException

Description copied from interface: RetrievalMethod

Dereferences the KeyInfo information referenced by this RetrievalMethod and applies the specified Transforms.

Specified by:

dereference in interface RetrievalMethod

Parameters:

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

Returns:

a Data 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.

Throws:

URIReferenceException - if there is an error while dereferencing
