- Field Detail
  - TYPE_UNDEFINED
```
public static final int TYPE_UNDEFINED
```
    This is used only when constraint is first created. This means that there is no value yet for the constraint.

    Constant Field Values
  - TYPE_LITERAL
```
public static final int TYPE_LITERAL
```
    This may be string, or number, anything really.
    
    See Also:
    
    Constant Field Values
  - TYPE_VARIABLE
```
public static final int TYPE_VARIABLE
```
    This is when it is set to a valid previously bound variable.
    
    See Also:
    
    Constant Field Values
  - TYPE_RET_VALUE
```
public static final int TYPE_RET_VALUE
```
    This is for a "formula" that calculates a value.
    
    See Also:
    
    Constant Field Values

```
public static final int TYPE_ENUM
```
    This is not used yet. ENUMs are not suitable for business rules until we can get data driven non code enums.

    Constant Field Values
  - TYPE_PREDICATE
```
public static final int TYPE_PREDICATE
