generateSuffixes

public static String[] generateSuffixes(int length)
Utility method that generates 0_, 1_ suffixes. Subclasses don't necessarily need to use this algorithm, but it is intended that they will in most cases.

Parameters:
length - The number of suffixes to generate
Returns:
The array of generated suffixes (with length=length).
