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.toString in interface QueryObjectsb - StringBuilder to append the string representation of this object to.public java.lang.StringBuilder toFullString(java.lang.StringBuilder sb)
StringBuilder.
For projection toString() method returns alias only. To get full projection string
one has to call toFullString() method.toFullString in interface Projectionsb - StringBuilder to append the string representation of this object to.public java.lang.String toFullString()
StringBuilder.
For projection toString() method returns alias only. To get full projection string
one has to call toFullString() method.toFullString in interface ProjectionIntalio Inc. (C) 1999-2008. All rights reserved http://www.intalio.com
