public class OperatorBetween
extends Operator

Represents the between operator. The left operand to between must be a single value and the right operand must be a list - this operator returns true if the left operand is between (using the registered comparator) the two elements in the list. The definition of between being inclusive follows the SQL BETWEEN definition.
