}

Constructs a CodeSigner object.

Parameters:

signerCertPath - The signer's certificate path. It must not be null.

timestamp - A signature timestamp. If null then no timestamp was generated for the signature.

Throws:

NullPointerException - if signerCertPath is null.

        if (obj == null || (!(obj instanceof CodeSigner))) {
            return false;

            }
        }
        return signerCertPath.equals(that.getSignerCertPath());
}

Tests for equality between the specified object and this code signer. Two code signers are considered equal if their signer certificate paths are equal and if their timestamps are equal, if present in both.

 public CertPath getSignerCertPath() 
{
        return signerCertPath;
}

Returns the signer's certificate path.

 public Timestamp getTimestamp() 
{
        return timestamp;
}

Returns the signature timestamp.

 public int hashCode() 
{
        if (myhash == -1) {
            if (timestamp == null) {
                myhash = signerCertPath.hashCode();
            } else {
                myhash = signerCertPath.hashCode() + timestamp.hashCode();
            }
        }
        return myhash;
}

Returns the hash code value for this code signer. The hash code is generated using the signer's certificate path and the timestamp, if present.

 public String toString() 
{
        StringBuffer sb = new StringBuffer();
        sb.append("(");
        sb.append("Signer: " + signerCertPath.getCertificates().get(0));
        if (timestamp != null) {
            sb.append("timestamp: " + timestamp);
        }
        sb.append(")");
        return sb.toString();
}

Returns a string describing this code signer.
