    Addresses are 42 characters hexadecimal strings. They begin with "c8" followed by 40 lowercase hexadecimal characters (0-9a-f).
    Addresses are calculated using a SHA-1 of the components of the construct path.
    To enable refactorings of construct trees, constructs with the ID Default will be excluded from the calculation. In those cases constructs in the same tree may have the same addreess.
    Example:
    
    c83a2846e506bcc5f10682b564084bca2d275709ee

```
    The full, absolute path of this construct in the tree.
    Components are separated by '/'.

@NotNull
public List<IConstruct> getScopes()
```
    All parent scopes of this construct.

    Includes all components of the tree.
  - getScope
```
@Stability(Stable)
@Nullable
public IConstruct getScope()
```
    Returns the scope in which this construct is defined.
    The value is undefined at the root of the construct scope tree.
  - getDefaultChild
```
@Stability(Stable)
@Nullable
public IConstruct getDefaultChild()
```
    Returns the child construct that has the id `Default` or `Resource"`.
    This is usually the construct that provides the bulk of the underlying functionality. Useful for modifications of the underlying construct that are not available at the higher levels. Override the defaultChild property.
    This should only be used in the cases where the correct default child is not named 'Resource' or 'Default' as it should be.
    If you set this to undefined, the default behavior of finding the child named 'Resource' or 'Default' will be used.
    
    Returns:
    
    a construct or undefined if there is no default child
  - setDefaultChild
```
@Stability(Stable)
public void setDefaultChild(@Nullable
                            IConstruct value)
```
    Returns the child construct that has the id `Default` or `Resource"`.
    This is usually the construct that provides the bulk of the underlying functionality. Useful for modifications of the underlying construct that are not available at the higher levels. Override the defaultChild property.
    This should only be used in the cases where the correct default child is not named 'Resource' or 'Default' as it should be.
    If you set this to undefined, the default behavior of finding the child named 'Resource' or 'Default' will be used.
