appendAsEJBQLpublic void appendAsEJBQL(List<Object> parameterAccumulator, Appendable out, String rootId) throws IOException Description copied from class:ExpressionStores a String representation of Expression as EJBQL using a provided PrintWriter. DB path expressions produce non-standard EJBQL path expressions. If the parameterAccumulator is supplied then as the EJBQL is output, it may load parameters into this list. In this case, the EJBQL output will contain reference to positional parameters. If no parameterAccumulator is supplied and a scalar type is encountered for which there is no EJBQL literal representation (such as dates) then this method will throw a runtime exception to indicate that it was not possible to generate a string-only representation of the Expression in EJBQL.- Overrides:
- appendAsEJBQLin class- ASTScalar
- Throws:
- IOException

- 4.0
