Expand description

Manages browsing state (e.g. LocalStorage, cookies, etc) associated with a set of [Frame].

Variants§

§

CreateFrame

Fields

§frame: ServerEnd<FrameMarker>
§control_handle: ContextControlHandle

Creates a new [Frame] under this [Context]. Destruction of a [Context] triggers the destruction of all of its associated [Frame]. [Frame] can be transferred to another component but cannot be shared across multiple components.

  • frame: An interface request that will be bound to the created [Frame].
§

CreateFrameWithParams

Fields

§frame: ServerEnd<FrameMarker>
§control_handle: ContextControlHandle

Similar to [Context.CreateFrame], with extra parameters.

  • params: The configuration used to create the [Frame]. This method will fail with ZX_ERR_INVALID_ARGS if the table is not clonable.
  • frame: An interface request that will be bound to the created [Frame].
§

GetCookieManager

Fields

§manager: ServerEnd<CookieManagerMarker>
§control_handle: ContextControlHandle

Used to observe cookies for sites hosted under this Context.

§

GetRemoteDebuggingPort

Waits until debugging is available on one or more Frames, and returns the DevTools port number. Multiple calls may be queued to received the port number.

If an error occurred, the ContextError will be set to this value:

  • REMOTE_DEBUGGING_PORT_NOT_OPENED: remote_debugging_port was not set in CreateContextParams or the remote debugging service failed to start.
