Class RDFSigner

java.lang.Object
  org.rdfcontext.signing.RDFSigner

public class RDFSigner

extends java.lang.Object

This object manipulate a given signed (or not signed) RDF/XML. It build a signature report list, it can add or delete a report in the list. Moreover it can paste the valid signature on the graph

Constructor Summary

RDFSigner(com.hp.hpl.jena.rdf.model.Model originalModel)
Deprecated. This constructor create a signr given a generic Model. The signature process works only on MSGs!

RDFSigner(com.hp.hpl.jena.rdf.model.Model originalModel, IURLResolver customURLResolver)
Deprecated. This constructor create a signr given a generic Model. The signature process works only on MSGs!

RDFSigner(MSG msgToBeSigned)
Default constructor.

RDFSigner(MSG msgToBeSigned, IURLResolver customURLResolver)

Method Summary

void	addSignatureReport(SignatureReport sr) Add a SignatureReport to the signatureList
com.hp.hpl.jena.rdf.model.Model	getSignedModel() Returns the signed version of the model (=cleanmodel + signatures in the current report) The Signature
boolean	isAllValid() return true if all the signature in the signatureList has valid
java.util.ArrayList	listSignatureReports()
boolean	signModel(LiveDBinSignature liveSign) Signs a model using the given LiveSignature and the DefaultURLResolver to check the availability of the certificate.
boolean	signModel(LiveDBinSignature liveSign, IURLResolver resolver) Sign the current model (passed by Constructor) using the specified LiveDBinSignature.

Parameters:

originalModel -

RDFSigner

public RDFSigner(MSG msgToBeSigned)

Default constructor. This class signs an MSG reifing a random triple containded in it, it is not ment to sing a generic graph, ony MSG will be correctly signed. Certificate availability will be checked using the DefaultURLResolver.

RDFSigner

public RDFSigner(MSG msgToBeSigned,

Parameters:

msgToBeSigned - - the MSG to be signed

customURLResolver - - the URL resolver to be used to verify the availability of the online certificate.
