interface snip-class-list<%> : interface?

Each eventspace has its own instance of snip-class-list<%>, obtained with (get-the-snip-class-list). New instances cannot be created directly. Each instance keeps a list of snip classes. This list is needed for loading snips from a file. See also Snip Classes.

> snipclass : (is-a?/c snip-class%)

Adds a snip class to the list. If a class with the same name already exists in the list, this one will not be added.

> → (or/c (is-a?/c snip-class%) #f)
> name : string?

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

> method (send a-snip-class-list find-position class)
> → exact-nonnegative-integer?
> class : (is-a?/c snip-class%)

Returns an index into the list for the specified class.

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