Each eventspace has an instance of @scheme[editor-data-class-list<%>],
|
|
obtained with @scheme[(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 @|editordatadiscuss|.

@defmethod[(add [snipclass (is-a?/c editor-data-class%)])

|

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

}

Finds a snip data class from the list with the given name, returning

@scheme[#f] if none can be found.

Returns the @scheme[n]th class in the list (counting from 0), returning

@scheme[#f] if the list has @scheme[n] or less classes.
