postInstantiate

protected void postInstantiate()

Description copied from class: Loader

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).
