Details

note

This method is defined in the undo extension, so you need to enable the undo plugin. Read the details in the Undo/Redo Functionality article.

The returned stack is an array of the redo user actions. Each user action contains a set of commands. A command is an object with the following attributes:

• type - (string) the type of a command: "add/remove/update"
• entity - (string) the type of the object which was changed: "task" or "link"
• value - (object) the changed task/link object
• oldValue - (object) the task/link object before changes

Have a look at the example below:

The getRedoStack() method returns a stack with 3 redo user actions. The first and second actions contain 1 command each, while the third one has 3 commands.
