Interface Target

public interface Target
Supports additional targets discovery and allows to attach to them.

  • Method Details

    • activateTarget

      void activateTarget(String targetId)
      Activates (focuses) the target.

    • attachToBrowserTarget

      String attachToTarget(String targetId, Boolean flatten)
      Attaches to the target with given id.
      Parameters:

    • autoAttachRelated

      void autoAttachRelated(String targetId, Boolean waitForDebuggerOnStart)
      Adds the specified target to the list of targets that will be monitored for any related target creation (such as child frames, child workers and new versions of service worker) and reported through attachedToTarget.
