Runtime Objects¶

The main objects provided are shown below in their default configuration.

In each object only some key members / properties are shown, the role of these and their scope is explained below:

• A Config object holds the set of current options alongside a ThebeEvents instance. A configuration culd be provided per application or per page.
  • ThebeEvents is an object that provided jquery-like events interface trigger, on, one, off, all objects that receive the `configc instance will use the same events object.
• A ThebeServer holds the SessionManager (ServiceManager in the case of JupyterLite)
  • it provides member function to establish a connecton
  • it provides functions to start a new or connect to an existing session/kernel
• A ThebeSession holds a kernel connection and is used to interact with the kernel
  • The session also creates an instance of a WidgetManager that is shared between all RendermimeRegistryies in notebooks or cells that attach to it
• A ThebeNotebook holds a list of cells and provides funcitons to load source code into cells and execute them
  • A notebook holds a RendermimeRegistry that is shared with aii it's cells
• A ThebeCell holds source code and can be executed in a session.
  • ThebeCell inherits from PassiveThebeCell which is only concerned with attaching to the DOM and rendering an OutputArea
  • If created independently of a ThebeNotebook it will hold it's own instance of a RendermimeRegistry
