@FunctionalInterface
public interface FileEditorState

This object is used to store/restore editor state between restarts. For example, text editor can store caret position, scroll position, information about folded regions, etc.

Undo subsystem expects a sensible implementation of Object.equals(Object) method of state instances. In particular, state1 and state2 in the following situation

   FileEditorState state1 = fileEditor.getState(FileEditorStateLevel.UNDO);
   ...
   fileEditor.setState(state1);
   FileEditorState state2 = fileEditor.getState(FileEditorStateLevel.UNDO);
 

are expected to be 'equal'.
