getOperator
Get operator of the compound expression.- Returns:
- Operator of the compound expression.
-
addExpression
Add expression to the end of the list.- Parameters:
expression
- Expression to add to end of list.
-
getExpressions
Get list of expressions.- Returns:

toString
Append a string representation of the object to the givenStringBuilder
. 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.- Parameters:
sb
- StringBuilder to append the string representation of this object to.- Returns:
- Same instance of StringBuilder given as parameter.
