object-with-elements

In the DRM, the generics element and element-setter are specified to operate on instances of <collection>.

In the Open Dylan C-FFI, <C-statically-typed-pointer> would be much more useful if element and element-setter could be used with it, especially via the sugar syntax using [], but they needn’t support any other collection operations such as do or map.

To accommodate this, Open Dylan provides 2 additional classes in the hierarchy provided by the standard library:

• <object-with-elements>

• <mutable-object-with-elements>

<object-with-elements> Open Abstract Class

An invented superclass of collections and any other object to which element is applicable.

Superclasses:

<object>

Operations:

• element

See also:

• <mutable-object-with-elements>

<mutable-object-with-elements> Open Abstract Class

An invented superclass of mutable collections and any other object to which element-setter is applicable.

Superclasses:

<object-with-elements>

Operations:

• element-setter
