- - ### Constructor Detail

    - #### 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 Detail

    - #### 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
