Parameters:

query - The CQL Query to translate into HQL

eliminateSubclasses - A flag indicating that the query should be formulated to avoid returning subclass instances of the targeted class.

caseInsensitive - A flag indicating that the query should be made case insensitive by converting all values to lowercase.

Returns:

An HQL query

Throws:

QueryProcessingException
