Methods

`Abstract`apply

apply(editor: Editor): void | Promise<void>
Parameters
- editor: Editor
Returns void | Promise<void>
Inherited from Command.apply
- Defined in js-draw/src/commands/Command.ts:10

`Abstract`description

description(editor: Editor, localizationTable: EditorLocalization): string
Parameters
- editor: Editor
- localizationTable: EditorLocalization
Returns string
Inherited from Command.description
- Defined in js-draw/src/commands/Command.ts:16

onDrop

onDrop(_editor: Editor): void
Called when the command is being deleted
Parameters
- _editor: Editor
Returns void

serialize

serialize(): Record<string | symbol, any>

Do not rely on the stability of the optupt of this function — it can change form without a major version increase.

Returns Record<string | symbol, any>
- Defined in js-draw/src/commands/SerializableCommand.ts:38

`Protected` `Abstract`serializeToJSON

serializeToJSON(): string | any[] | Record<string, any>
Returns string | any[] | Record<string, any>

Parameters
- editor: Editor
Returns void | Promise<void>
Inherited from Command.unapply
- Defined in js-draw/src/commands/Command.ts:11

`Static`deserialize

deserialize(
data: string | Record<string, any>,
editor: Editor,
): SerializableCommand
Convert a string containing JSON data (or the output of JSON.parse) into a Command.

Implementations should assume that data is untrusted.
Parameters
- data: string | Record<string, any>
- editor: Editor
Returns SerializableCommand
- Defined in js-draw/src/commands/SerializableCommand.ts:49

`Static`register

register(commandTypeId: string, deserialize: DeserializationCallback): void
Register a deserialization callback. This must be called at least once for every subclass of SerializableCommand.
Parameters
- commandTypeId: string
- deserialize: DeserializationCallback
Returns void
- Defined in js-draw/src/commands/SerializableCommand.ts:65

`Static`union

union(a: Command, b: Command): Command
Parameters
- a: Command
- b: Command
Returns Command
