StringBuilder
.
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.
sb
- StringBuilder to append the string representation of this object to.
