  - ### SetProperty

    protected SetProperty(String name, Expression expression, Class<V> entityType)
    Constructs a new property with the given name and expression
    Parameters:
      `name` - of the property (will be used as alias for the expression)
      `expression` - expression for property
      `entityType` - type of related entity

- ## Method Details

  - ### alias

    public SetProperty<V> alias(String alias)
    Creates alias with different name for this property
    Overrides:
      `alias` in class `BaseProperty<Set<V extends Persistent>>`

  - ### outer

    public SetProperty<V> outer()
    Returns a version of this property that represents an OUTER join. It is up to caller to ensure that the property corresponds to a relationship, as "outer" attributes make no sense.

  - ### enclosing

    public SetProperty<V> enclosing()
    Overrides:
      `enclosing` in class `BaseProperty<Set<V extends Persistent>>`
    Returns:
      property that will be translated relative to parent query
