Modifier and Type	Method	Description
`protected BigDecimal`	`argToDB(Object arg)`
`Object`	`evaluate(State state)`
`int`	`getNodeType()`	QDL is not strongly typed but Java is, so each node type should have a unique integer and conditionals should use that, not the instanceof operator.
`ExpressionInterface`	`makeCopy()`

    Description copied from interface: ExpressionInterface
    
    QDL is not strongly typed but Java is, so each node type should have a unique integer and conditionals should use that, not the instanceof operator. This allows for efficient programming with switch statements rather than a bevy of conditionals (potentially each of which gets done even if the correct case has been handled).
