      • getTimestamp

        public Date getTimestamp()
        Returns the date and time when the timestamp was generated.
        Returns:
        The timestamp's date and time.

      • getSignerCertPath

        public CertPath getSignerCertPath()
        Returns the certificate path for the Timestamping Authority.
        Returns:
        The TSA's certificate path.

      • equals

        public boolean equals(Object obj)
        Tests for equality between the specified object and this timestamp. Two timestamps are considered equal if the date and time of their timestamp's and their signer's certificate paths are equal.
        Overrides:
        equals in class  Object
        Parameters:
        obj - the object to test for equality with this timestamp.
        Returns:
        true if the timestamp are considered equal, false otherwise.

      • toString

        public String toString()
        Returns a string describing this timestamp.
        Overrides:
        toString in class  Object
        Returns:
        A string comprising the date and time of the timestamp and its signer's certificate.
