Template:ImportingClasses

This template is for use by the scripting language documentation, to explain that Java classes must be imported in order to use them in the script.

Example

{{ImportingClasses | lang = JavaScript}}

To reference Java classes from JavaScript you will need to import them.

Unlike ImageJ 1.x, ImageJ2 (and therefore Fiji) does not automatically import any classes. Consequently, scripts written for ImageJ 1.x will not run in ImageJ2 without adding the proper imports. The rationale is that the auto-import feature is not safe. What if two classes of the same name live in two different packages? Or if a new class is introduced that makes formerly unique names ambiguous? All of a sudden, all of the scripts that reference the original class no longer work. In short: auto-imports are dangerously imprecise.
