public class OSnLNodeVariable
extends OSnLNode

The OSnLNodeVariable class represents a variable node in an expression tree. The variable can be treated as a unary operator with its index as a subscript operand of the "variable operator". If the variable index is a number, there is no operand node. The number is treated as the variables attribute. If the variable index is an integer-valued function or a look up from some data source, it is treated no different from a unary operator. It extends the abstract OSnLNode class and implements its abstract methods such as calculateFunction(double[]).
