Object
- VarInfoAux

All Implemented Interfaces:

Serializable, Cloneable
```
public final class VarInfoAux
extends Object
implements Cloneable, Serializable
```
Represents additional information about a VarInfo that front ends tell Daikon. For example, whether order matters in a collection. This is immutable and interned.

    Constant Field Values
  - IS_PARAM
```
public static final String IS_PARAM
```
    Whether this variable is a parameter to a method, or derived from a parameter to a method. By default, if p is a parameter, then some EXIT invariants related to p aren't printed. However, this does not affect the computation of invariants.
    Frontends are responsible for setting if p is a parameter and if p.a is a parameter. In Java, p.a is not a parameter, whereas in IOA, it is.

    See Also:
    
    Constant Field Values
  - MINIMUM_VALUE
```
public static final String MINIMUM_VALUE

    Indicates the minimum value of the scalar variable or the vector elements, if there's any.
    
    See Also:
    
    Constant Field Values
  - MAXIMUM_VALUE
```
public static final String MAXIMUM_VALUE
```
    Indicates the maximum value of the scalar variable or the vector elements, if there's any.
    
    See Also:
    
    Constant Field Values
  - VALID_VALUES
```
public static final String VALID_VALUES
```
    Indicates the valid values (using string representation) for the elements of the vector, if there's any. Values are enclosed in square brackets, and each element is quoted separately, e.g.: ["a" "b"]. Parsing will be done upon call of the getList() method.

    getList(String), Constant Field Values
  - IS_STRUCT
```
public static final String IS_STRUCT
```
    Whether this variable is an inline structure. By default, a variable is a reference to a structure (class). If it is an inlined structure (or array), it doesn't make sense to look for invariants over its hashcode. Front ends include references to inlined structures as variables because some tools that follow daikon need other information about the variable.
    
    See Also:
    
    Constant Field Values
  - IS_NON_NULL
```
public static final String IS_NON_NULL
```
    Whether this variable is known to be non-null, such as "this" in a Java program.
    
    See Also:
    
    Constant Field Values
  - PACKAGE_NAME
```
public static final String PACKAGE_NAME
```
    Java-specific. The package name of the class that declares this variable, if the variable is a field. If it's not a field of some class, the value of this key is "no_package_name_string".
