parse

public static VersionInfo parse(String version)
                         throws NumberFormatException

Returns:

The parsed VersionInfo - or null if empty input

Throws:

NumberFormatException - If failed to parse any of the components

IllegalArgumentException - If any of the parsed components is negative
