Class ASTTrue

  • All Implemented Interfaces:
    Serializable, Node, XMLSerializable

    public class ASTTrue
    extends ConditionNode
    Boolean true expression element Notice that there is one ASTTrue and one ASTFalse instead of a ASTBoolean with a Boolean value. The main reason for doing this is that a common ASTBoolean will have operand count of 1 and that will default to a prepared statmenet like " where ? and (...)", but we only need " where true and (...)".

        public void appendAsEJBQL​(List<Object> parameterAccumulator,
                                  Appendable out,

                           throws IOException
        Description copied from class: Expression
        Stores 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.
