  - EnumTypeStateObject
```
public EnumTypeStateObject(StateObject parent)
```
    Creates a new EnumTypeStateObject.
    
    Parameters:
    
    parent - The parent of this state object, which cannot be null
    
    Throws:
    
    NullPointerException - The given parent cannot be null
  - EnumTypeStateObject
```
public EnumTypeStateObject(StateObject parent,
                           Enum<? extends Enum<?>> enumConstant)
```
    Creates a new EnumTypeStateObject.
    
    Parameters:
    
    parent - The parent of this state object, which cannot be null
    
    enumConstant - The fully qualified name of the Enum type following by the constant
    
    Throws:
    
    NullPointerException - The given parent cannot be null
  - EnumTypeStateObject
```
public EnumTypeStateObject(StateObject parent,
                           String enumConstant)
```
    Creates a new EnumTypeStateObject.
    
    Parameters:
    
    parent - The parent of this state object, which cannot be null
    
    enumConstant - The fully qualified name of the Enum constant
    
    Throws:
    
    NullPointerException - The given parent cannot be null

  - accept
```
public void accept(StateObjectVisitor visitor)
```
    Visits this StateObject by the given visitor.
    
    Parameters:
    
    visitor - The visitor to visit this object
  - getExpression
```
public AbstractPathExpression getExpression()
```
    Returns the actual parsed object if this StateObject representation of the JPQL query was created by parsing an existing JPQL query.
    
    Specified by:
    
    getExpression in interface StateObject
    
    Overrides:
    
    getExpression in class AbstractStateObject
    
    Returns:
    
    The parsed object when a JPQL query is parsed and converted into a StateObject or null when the JPQL query is manually created (i.e. not from a string)
  - setExpression
```
public void setExpression(AbstractPathExpression expression)
```
    Keeps a reference of the parsed object object, which should only be done when this object is instantiated during the conversion of a parsed JPQL query into StateObjects.
    
    Parameters:
    
    expression - The parsed object representing the enum type
