DynamicFilterParameterSpecification

public class DynamicFilterParameterSpecification extends Object implements ParameterSpecification
A specialized ParameterSpecification impl for dealing with a dynamic filter parameters.

Note: this class is currently not used. The ideal way to deal with dynamic filter parameters for HQL would be to track them just as we do with other parameters in the translator. However, the problem with that is that we currently do not know the filters which actually apply to the query; we know the active/enabled ones, but not the ones that actually "make it into" the resulting query.
