com.mysema.query.types.QTuple

QTuple represents a projection of type Tuple

Usage example:

 {@code List result = query.from(employee).list(new QTuple(employee.firstName, employee.lastName));}for (Tuple row : result)  System.out.println("firstName " + row.get(employee.firstName)); System.out.println("lastName " + row.get(employee.lastName)); }}

Since Tuple projection is the default for multi column projections, the above is equivalent to this code

 {@code List result = query.from(employee).list(employee.firstName, employee.lastName);}for (Tuple row : result)  System.out.println("firstName " + row.get(employee.firstName)); System.out.println("lastName " + row.get(employee.lastName)); }}
