Creates a new FESCriterionGenerator.

Parameters:

criteria - the criteria

unsupportedIsTrue - if the generator encounters a filter expression it could not translate it may generate a criterion that is always true or always false depending on this flag

matchDomainIds - if filter on observation parameters like feature, offering or procedure should match on their respective domain identifiers or on the primary keys in the database

complexParent - if the queries should result in the parent observation and hide the child observations
