Detailed Description

AST Abstract Operator Node.

This class is the abstract base class in the Abstract Syntax Tree for all operators. An Operator is an instruction to the virtual machine to take some action. Operators form the content of a Block. As this is the base class of all operators, the Operator class only provides the functionality that is common to all operators: getting the number of operands (getNumOperands), getting the Value of an operand (getOperand), and setting the Value of an operand (setOperand). Since Operand is a Value, this implies two things: (1) Operators can be the operand of other operators and (2) eery Operator has a type.
