```
public AdditionExpressionStateObject(StateObject parent)
```
    Creates a new AdditionExpressionStateObject.
    
    Parameters:
    
    parent - The parent of this state object, which cannot be null
    
    Throws:
    
    NullPointerException - The given parent cannot be null
  - AdditionExpressionStateObject
```
public AdditionExpressionStateObject(StateObject parent,
                                     StateObject leftStateObject,
                                     StateObject rightStateObject)
```
    Creates a new AdditionExpressionStateObject.
    
    Parameters:
    
    parent - The parent of this state object, which cannot be null
    
    leftStateObject - The StateObject representing the left expression
    
    rightStateObject - The StateObject representing the right expression
    
    Throws:
    
    NullPointerException - The given parent cannot be null
  - AdditionExpressionStateObject
```
public AdditionExpressionStateObject(StateObject parent,
                                     String leftJpqlFragment,
                                     String rightJpqlFragment)
```
    Creates a new AdditionExpressionStateObject.
    
    Parameters:
    
    parent - The parent of this state object, which cannot be null
    
    leftJpqlFragment - The string representation of the left expression to parse and to convert into a StateObject
    
    rightJpqlFragment - The string representation of the right expression to parse and to convert into a StateObject
    
    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 AdditionExpression 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 ArithmeticExpressionStateObject
    
    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)
  - getIdentifier
```
public String getIdentifier()
```
    Returns the identifier joining the two StateObjects.
    
    Specified by:
    
    getIdentifier in class CompoundExpressionStateObject
    
    Returns:
    
    The JPQL identifier join two expressions
  - setExpression
```
public void setExpression(AdditionExpression 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 an addition expression
