All Implemented Interfaces:

java.io.Serializable, java.lang.Cloneable, LValue
```
public class Term
extends AbstractLValue
```
An term is a list of LValues connected by operators. For the sake of efficiency, this is not stored as tree. We store the term as a list in the following format: (headValue)(OP value)* ...

Modifier and Type	Method	Description
`void`	`add(InfixOperator operator, LValue operand)`
`java.lang.Object`	`clone()`
`TypeValuePair`	`evaluate()`
`LValue[]`	`getChildValues()`	Returns any dependent lvalues (parameters and operands, mostly).

```
public LValue[] getChildValues()
```
    Returns any dependent lvalues (parameters and operands, mostly).
