  org.rdfcontext.signing.SignatureReport

public class SignatureReport

extends java.lang.Object

An immutable object representing a piece of signed data. It contains the signature's information. It also can check for validity of the signature and for integrity of signed data. NOTE: SignatureReports can be extracted from an RDF Graph using the RDFSigner utility.

Constructor Summary

SignatureReport(LiveDBinSignature live, java.lang.String data, IURLResolver urlResolver)
Deprecated. This constructor might not been used. The right way to sign data is via RDFSigner.signModel() method.

SignatureReport(java.lang.String data, java.lang.String signatureValue, java.net.URL publicKey, java.lang.String kindOfCertificate, IURLResolver urlresolver)
Build a new signature report from the given data, signature value, certificate URI and the kind of certificate This constructor is used by the RDFSigner object.
