## Detailed Description

Link annot object.

## Member Function Documentation

## ◆ getAction()

Link::getAction | ( |  | ) |
| inline

Get link's action.

Returns
  Action - An action object.

## ◆ getHighlightingMode()

Link::getHighlightingMode | ( |  | ) |
| inline

Get link's highlight mode.

Returns
  number - An integer indicating highlight mode. Please refer to Highlight_Mode.

## ◆ removeAction()

Link::removeAction | ( |  | trigger = `-1`,
|  |  | action,
|  |  | isObjectNumber = `false`
| ) |  |
| inline

Remove link's action.

Parameters

  [trigger=-1] | number - The trigger parameter. If `isObjectNumber` is true, represents the object number of action to remove. If `isObjectNumber` is false, represents the trigger event type.
  [action] | Action - The action to be removed. If first parameter is an object number, this parameter is not required.
  [isObjectNumber=false] | boolean - Whether the first parameter is an object number. If true, it will call the base class's removeAction method.

Returns
  Promise<boolean> - A boolean value indicating whether the action was successfully removed.

Deprecated:
  - For removing additional actions purpose, please use AdditionalAction<T>.removeAction instead
  - For removing action purpose, you must pass the `trigger` parameter as an object number and set `isObjectNumber` to true.
    In the future, this method will be simplified to remove actions only, and no additional parameters will be required.

Note
  For historical reasons, since version 11.0.0, this method add a new parameter `isObjectNumber` to determine whether the first parameter is an object number,
  if it is, it will call the Annot.removeAction method to remove the action with the object number,
  otherwise it will remove an additional action with specified trigger and Action instance.
  The `isObjectNumber` parameter is used for API compatibility, it is not used for removing additional actions.
  - To remove an action, you must pass the `trigger` parameter as an object number and set `isObjectNumber` to true.
    The `action` parameter should be omitted (pass null).
    Example:
    // Remove an action with object number 0
    linkAnnot.removeAction(0, null, true);
  - To remove an additional action, you should use AdditionalAction<T>.removeAction method, this method is only used internally.
