public interface Operator
extends Expression

Interface that represents an operator expression. An operator is associated with operands. For FM-Classic, an operator can be either a unary operator (takes one operand), or a binary operator (takes two operands).

Operators have precedence. Precedence between operators is determined by the getPrecedence() method. This provides a way for ExpressionBuilder to determine what precedence each operator has.
