RedoCommand (undo)

@ckeditor/ckeditor5-undo/src/redocommand

class

The redo command stores batches that were used to undo a batch by UndoCommand. It is able to redo a previously undone batch by reversing the undoing batches created by UndoCommand. The reversed batch is transformed by all the batches from history that happened after the reversed undo batch.

The redo command also takes care of restoring the document selection.

Properties

inherited
affectsData : boolean

See source
A flag indicating whether a command execution changes the editor data or not.

Commands with affectsData set to false will not be automatically disabled in the read-only mode and other editor modes with restricted user write permissions.

Note: You do not have to set it for your every command. It is true by default.

Parameters

affectsData : boolean
readonly inherited
createdBatches : WeakSet<Batch>

See source
Returns all batches created by this command.
readonly inherited
editor : Editor

See source
The editor on which this command will be used.
inherited observable
isEnabled : boolean

See source
Flag indicating whether a command is enabled or disabled. A disabled command will do nothing when executed.

A given command class should control this value by overriding the refresh() method.

It is possible to disable a command "from outside" using forceDisabled method.
inherited observable
value : unknown

See source
The value of the command. A given command class should define what it represents for it.

For example, the 'bold' command's value indicates whether the selection starts in a bolded text. And the value of the 'link' command may be an object with link details.

It is possible for a command to have no value (e.g. for stateless actions such as 'uploadImage').

A given command class should control this value by overriding the refresh() method.
internal inherited
_createdBatches : WeakSet<Batch>

See source
Stores all batches that were created by this command.
protected inherited
_isEnabledBasedOnSelection : boolean

See source
A flag indicating whether a command's isEnabled state should be changed depending on where the document selection is placed.

By default, it is set to true. If the document selection is placed in a non-editable place (such as non-editable root), the command becomes disabled.

The flag should be changed to false in a concrete command's constructor if the command should not change its isEnabled accordingly to the document selection.
protected inherited
_stack : Array<object>
See source
Stack of items stored by the command. These are pairs of:
- batch saved by the command,
- selection state at the moment of saving the batch.

Methods

inherited
constructor( editor )

See source

Parameters

editor : Editor
inherited
addBatch( batch ) → void

See source
Stores a batch in the command, together with the selection state of the document created by the editor which this command is registered to.

Parameters

batch : Batch

The batch to add.

Returns

bind( bindProperty1, bindProperty2 ) → DualBindChain<K1, RedoCommand[ K1 ], K2, RedoCommand[ K2 ]>
See source
Binds observable properties to other objects implementing the Observable interface.

Read more in the dedicated guide covering the topic of property bindings with some additional examples.

Consider two objects: a button and an associated command (both Observable).

A simple property binding could be as follows:
```
button.bind( 'isEnabled' ).to( command, 'isEnabled' );
```
or even shorter:
```
button.bind( 'isEnabled' ).to( command );
```
which works in the following way:
- button.isEnabled instantly equals command.isEnabled,
- whenever command.isEnabled changes, button.isEnabled will immediately reflect its value.
Note: To release the binding, use unbind.

You can also "rename" the property in the binding by specifying the new name in the to() chain:
```
button.bind( 'isEnabled' ).to( command, 'isWorking' );
```
It is possible to bind more than one property at a time to shorten the code:
```
button.bind( 'isEnabled', 'value' ).to( command );
```
which corresponds to:
```
button.bind( 'isEnabled' ).to( command );
button.bind( 'value' ).to( command );
```
The binding can include more than one observable, combining multiple data sources in a custom callback:
```
button.bind( 'isEnabled' ).to( command, 'isEnabled', ui, 'isVisible',
	( isCommandEnabled, isUIVisible ) => isCommandEnabled && isUIVisible );
```
Using a custom callback allows processing the value before passing it to the target property:
```
button.bind( 'isEnabled' ).to( command, 'value', value => value === 'heading1' );
```
It is also possible to bind to the same property in an array of observables. To bind a button to multiple commands (also Observables) so that each and every one of them must be enabled for the button to become enabled, use the following code:
```
button.bind( 'isEnabled' ).toMany( [ commandA, commandB, commandC ], 'isEnabled',
	( isAEnabled, isBEnabled, isCEnabled ) => isAEnabled && isBEnabled && isCEnabled );
```

Returns

void
inherited
clearStack() → void

See source
Removes all items from the stack.

Returns

void
inherited
decorate( methodName ) → void
See source
Turns the given methods of this object into event-based ones. This means that the new method will fire an event (named after the method) and the original action will be plugged as a listener to that event.

Read more in the dedicated guide covering the topic of decorating methods with some additional examples.

Decorating the method does not change its behavior (it only adds an event), but it allows to modify it later on by listening to the method's event.

For example, to cancel the method execution the event can be stopped:
```
class Foo extends ObservableMixin() {
	constructor() {
		super();
		this.decorate( 'method' );
	}

	method() {
		console.log( 'called!' );
	}
}

const foo = new Foo();
foo.on( 'method', ( evt ) => {
	evt.stop();
}, { priority: 'high' } );

foo.method(); // Nothing is logged.
```
Note: The high priority listener has been used to execute this particular callback before the one which calls the original method (which uses the "normal" priority).

It is also possible to change the returned value:
```
foo.on( 'method', ( evt ) => {
	evt.return = 'Foo!';
} );

foo.method(); // -> 'Foo'
```
Finally, it is possible to access and modify the arguments the method is called with:
```
method( a, b ) {
	console.log( `${ a }, ${ b }`  );
}

// ...

foo.on( 'method', ( evt, args ) => {
	args[ 0 ] = 3;

	console.log( args[ 1 ] ); // -> 2
}, { priority: 'high' } );

foo.method( 1, 2 ); // -> '3, 2'
```
Parameters

methodName : 'off' | 'on' | 'once' | 'listenTo' | 'stopListening' | 'fire' | 'delegate' | 'stopDelegating' | 'set' | 'bind' | 'unbind' | 'decorate' | 'destroy' | 'value' | 'execute' | 'isEnabled' | 'affectsData' | 'refresh' | 'editor' | 'forceDisabled' | 'clearForceDisabled' | '_createdBatches' | 'createdBatches' | 'addBatch' | 'clearStack'

Name of the method to decorate.

Returns

void
inherited
delegate( events ) → EmitterMixinDelegateChain
See source
Delegates selected events to another Emitter. For instance:
```
emitterA.delegate( 'eventX' ).to( emitterB );
emitterA.delegate( 'eventX', 'eventY' ).to( emitterC );
```
then eventX is delegated (fired by) emitterB and emitterC along with data:
```
emitterA.fire( 'eventX', data );
```
and eventY is delegated (fired by) emitterC along with data:
```
emitterA.fire( 'eventY', data );
```
Parameters

events : Array<string>

Event names that will be delegated to another emitter.

Returns

EmitterMixinDelegateChain
inherited
destroy() → void

See source
Destroys the command.

Returns

void
execute() → void
See source
Executes the command. This method reverts the last batch added to the command's stack, applies the reverted and transformed version on the document and removes the batch from the stack. Then, it restores the document selection.

Returns

void

Fires
- execute
inherited
fire( eventOrInfo, args ) → GetEventInfo<TEvent>[ 'return' ]

See source
Fires an event, executing all callbacks registered for it.

The first parameter passed to callbacks is an EventInfo object, followed by the optional args provided in the fire() method call.

Type parameters

TEvent : extends BaseEvent

The type describing the event. See BaseEvent.

Parameters

eventOrInfo : GetNameOrEventInfo<TEvent>

The name of the event or EventInfo object if event is delegated.

args : TEvent[ 'args' ]

Additional arguments to be passed to the callbacks.

Returns

GetEventInfo<TEvent>[ 'return' ]

By default the method returns undefined. However, the return value can be changed by listeners through modification of the evt.return's property (the event info is the first param of every callback).
inherited
forceDisabled( id ) → void
See source
Disables the command.

Command may be disabled by multiple features or algorithms (at once). When disabling a command, unique id should be passed (e.g. the feature name). The same identifier should be used when enabling back the command. The command becomes enabled only after all features enabled it back.

Disabling and enabling a command:
```
command.isEnabled; // -> true
command.forceDisabled( 'MyFeature' );
command.isEnabled; // -> false
command.clearForceDisabled( 'MyFeature' );
command.isEnabled; // -> true
```
Command disabled by multiple features:
```
command.forceDisabled( 'MyFeature' );
command.forceDisabled( 'OtherFeature' );
command.clearForceDisabled( 'MyFeature' );
command.isEnabled; // -> false
command.clearForceDisabled( 'OtherFeature' );
command.isEnabled; // -> true
```
Multiple disabling with the same identifier is redundant:
```
command.forceDisabled( 'MyFeature' );
command.forceDisabled( 'MyFeature' );
command.clearForceDisabled( 'MyFeature' );
command.isEnabled; // -> true
```
Note: some commands or algorithms may have more complex logic when it comes to enabling or disabling certain commands, so the command might be still disabled after clearForceDisabled was used.

Parameters

id : string

Unique identifier for disabling. Use the same id when enabling back the command.

Returns

void
inherited
listenTo( emitter, event, callback, [ options ] ) → void
See source
Registers a callback function to be executed when an event is fired in a specific (emitter) object.

Events can be grouped in namespaces using :. When namespaced event is fired, it additionally fires all callbacks for that namespace.
```
// myEmitter.on( ... ) is a shorthand for myEmitter.listenTo( myEmitter, ... ).
myEmitter.on( 'myGroup', genericCallback );
myEmitter.on( 'myGroup:myEvent', specificCallback );

// genericCallback is fired.
myEmitter.fire( 'myGroup' );
// both genericCallback and specificCallback are fired.
myEmitter.fire( 'myGroup:myEvent' );
// genericCallback is fired even though there are no callbacks for "foo".
myEmitter.fire( 'myGroup:foo' );
```
An event callback can stop the event and set the return value of the fire method.

Type parameters

TEvent : extends BaseEvent

The type describing the event. See BaseEvent.

Parameters

emitter : Emitter

The object that fires the event.

event : TEvent[ 'name' ]

The name of the event.

The function to be called on event.

[ options ] : GetCallbackOptions<TEvent>

Additional options.

Returns

void
inherited
off( event, callback ) → void

See source
Stops executing the callback on the given event. Shorthand for this.stopListening( this, event, callback ).

Parameters

event : string

The name of the event.

callback : Function

The function to stop being called.

Returns

void
inherited
on( event, callback, [ options ] ) → void

See source
Registers a callback function to be executed when an event is fired.

Shorthand for this.listenTo( this, event, callback, options ) (it makes the emitter listen on itself).

Type parameters

TEvent : extends BaseEvent

The type descibing the event. See BaseEvent.

Parameters

event : TEvent[ 'name' ]

The name of the event.

callback : GetCallback<TEvent>

The function to be called on event.

[ options ] : GetCallbackOptions<TEvent>

Additional options.

Returns

void
inherited
once( event, callback, [ options ] ) → void

See source
Registers a callback function to be executed on the next time the event is fired only. This is similar to calling on followed by off in the callback.

Type parameters

TEvent : extends BaseEvent

The type descibing the event. See BaseEvent.

Parameters

event : TEvent[ 'name' ]

The name of the event.

callback : GetCallback<TEvent>

The function to be called on event.

[ options ] : GetCallbackOptions<TEvent>

Additional options.

Returns

void
inherited
refresh() → void

See source
Refreshes the command. The command should update its isEnabled and value properties in this method.

This method is automatically called when any changes are applied to the document.

Returns

void
inherited
set( values ) → void
See source
Creates and sets the value of an observable properties of this object. Such a property becomes a part of the state and is observable.

It accepts a single object literal containing key/value pairs with properties to be set.

This method throws the observable-set-cannot-override error if the observable instance already has a property with the given property name. This prevents from mistakenly overriding existing properties and methods, but means that foo.set( 'bar', 1 ) may be slightly slower than foo.bar = 1.

In TypeScript, those properties should be declared in class using declare keyword. In example:
```
public declare myProp1: number;
public declare myProp2: string;

constructor() {
	this.set( {
		'myProp1: 2,
		'myProp2: 'foo'
	} );
}
```
Parameters

values : object

An object with name=>value pairs.

Returns

void
inherited
set( name, value ) → void
