interface editor-data-class-list<%> : interface?

Each eventspace has an instance of editor-data-class-list<%>, obtained with (get-the-editor-data-class-list). New instances cannot be created directly. This list keeps a list of editor data classes; this list is needed for loading snips from a file. See also Editor Data.

> name : string?

Finds a snip data class from the list with the given name, returning #f if none can be found.

> → exact-nonnegative-integer?
> class : (is-a?/c editor-data-class%)

Returns an index into the list for the specified class.

> method (send an-editor-data-class-list nth n)
> → (or/c (is-a?/c editor-data-class%) #f)
