      • getEventListeners

        java.util.List<EventListener> getEventListeners​(java.lang.String objectId,
                                                java.lang.Integer depth,
                                                java.lang.Boolean pierce)
        Returns event listeners of the given object.
        Parameters:
        objectId - Identifier of the object to return listeners for.
        depth - The maximum depth at which Node children should be retrieved, defaults to 1. Use -1 for the entire subtree or provide an integer larger than 0.
        pierce - Whether or not iframes and shadow roots should be traversed when returning the subtree (default is false). Reports listeners for all contexts if pierce is enabled.
        Returns:
        Array of relevant listeners.
