org.eclipse.persistence.jpa.jpql.model.query.CaseExpressionStateObject
A CASE predicate is used to calculate a condition and when it's true, its THEN expression will be executed.
BNF: general_case_expression ::= CASE when_clause {when_clause}* ELSE scalar_expression END or
BNF: simple_case_expression ::= CASE case_operand simple_when_clause {simple_when_clause}* ELSE scalar_expression END
