History

Abstract Value Members

abstract def add(edit: NamedEdit): Unit

Add another edit to the history.
Add another edit to the history. Unless merging is blocked, it tries to merge this edit with the most recent edit. Afterwards, the internal merge-block flag is cleared.
abstract def blockMerge(): Unit

Disallow the merging of the next edit to be added.
Disallow the merging of the next edit to be added. This can be used to avoid merging edits if the editor component was temporarily unfocused, for example.
abstract def canRedo: Boolean

Whether there are edits that can be redone, and thus whether redo and redoName may be called.
abstract def canUndo: Boolean

Whether there are undoable edits and thus undo and undoName may be called.
abstract def capture[A](name: String, document: Document, terminal: Terminal)(block: ⇒ A): A

Creates an automatic edit from tracing events on a document and terminal.
Creates an automatic edit from tracing events on a document and terminal. The edit, if not empty, will be added to the history before returning.
name
the name of the resulting edit
document
the document to temporarily trace
terminal
the terminal to temporarily trace
block
an action that produces events as a side effect. These events will make up the edit.
abstract def clear(): Unit

Clears the history, removing all edits.
Clears the history, removing all edits. Afterwards, canUndo and canRedo will return false.
abstract def redo(): Unit

Throws an exception if !canRedo
abstract def redoName: String

Throws an exception if !canRedo
abstract def undo(): Unit

Throws an exception if !canUndo
abstract def undoName: String

Throws an exception if !canUndo
