public static String buildPowerOnDataFilter(org.eclipse.keypop.calypso.crypto.legacysam.sam.LegacySam.ProductType productType,
 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:

IllegalArgumentException - If productType is null.

IllegalArgumentException - If serialNumberRegex is null, empty or invalid.
