guessAliases

public static List<Subquery.Alias> guessAliases(String prefix,
 String objectAlias)

Given a prefix and an object alias, guess a reasonable sequence of aliases to use in a query.

FIXME: the prefix is not always a valid association path

If the prefix is something like: 'experimentalDesign.experimentalFactors.factorValues.' with the 'fv' alias, it is converted into:

join experimentalDesign as alias1 join alias1.experimentalFactors as alias2 join alias2.factorValues as fv

Parameters:

prefix - prefix under which the supplied object alias is accessible

objectAlias - ultimate alias to declare
