In general, the toString method for query objects appends a string that textually
represents this object. The result should be a query string that complies to EJB QL
specification as long as the query object represents a syntay element of it. It is
required that all subclasses override this method.
The toString method defined at class Object is overwritten and calls this method.toString
in interface QueryObject
sb
- StringBuilder to append the string representation of this object to.public java.lang.StringBuilder toFullString(java.lang.StringBuilder sb)

.
For projection toString() method returns alias only. To get full projection string
one has to call toFullString() method.toFullString
in interface Projection
