  - toString
```
public String toString()
```
    Returns a string in the format specified by Objects.toStringHelper(Object).
    After calling this method, you can keep adding more properties to later call toString() again and get a more complete representation of the same object; but properties cannot be removed, so this only allows limited reuse of the helper instance. The helper allows duplication of properties (multiple name/value pairs with the same name can be added).
    
    Overrides:
    
    toString in class Object
    
    Returns:
    never null
  - addHolder
```
private Objects.ToStringHelper.ValueHolder addHolder()
```
    Links a new Objects.ToStringHelper.ValueHolder to the tail of the values linked list and returns it.
    
    Returns:
    never null, always new instance
  - addHolder
```
private Objects.ToStringHelper addHolder(Object value)
```
    Adds an unnamed value to the formatted output.
    
    Parameters:
    value - value of property
    
    Returns:
    self for method chaining
  - addHolder
```
private Objects.ToStringHelper addHolder(String name,
                               Object value)
```
    Adds an named value to the formatted output.
    
    Parameters:
    name - name of property
    value - value of property
    
    Returns:
    self for method chaining
