        public static java.lang.String buildPowerOnDataFilter​(org.eclipse.keypop.calypso.crypto.legacysam.sam.LegacySam.ProductType productType,
                                                      java.lang.String serialNumberRegex)
        Create a regular expression to be used as "Power on data" filter in the selection process.

        Two criteria are available:

        • A filter to target SAMs having a specific LegacySam.ProductType.
        • A filter to target SAMs having a serial number matching a specific regular expression.

        Concerning the serial number, the regular expression is based on a hexadecimal representation of the number.

        Example:

        • A filter targeting all SAMs having an 8-byte serial number starting with A0h would be "^A0.{6}$".
        • A filter targeting a SAM having the exact serial number 12345678h would be "12345678".

        Both argument are optional and can be null.

        Parameters:
        productType - The target SAM product type.
        serialNumberRegex - A regular expression matching the SAM serial number.
        Returns:
        A not empty string containing a regular
        Throws:
        java.lang.IllegalArgumentException - If productType is null.
        java.lang.IllegalArgumentException - If serialNumberRegex is null, empty or invalid.
