This class is a `metaclass`_ for |Model| that is responsible for automatically cataloging all Bokeh models that get defined, so that the serialization machinery between Bokeh and BokehJS can function properly. .. note:: It is worth pointing out explicitly that this relies on the rules for Metaclass inheritance in Python. Bokeh works by replicating Python model objects (e.g. plots, ranges, data sources, which are all |HasProps| subclasses) into BokehJS. In the case of using a Bokeh server, the Bokeh model objects can also be synchronized bidirectionally. This is accomplished by serializing the models to and from a JSON format, that includes the name of the model type as part of the payload, as well as a unique ID, and all the attributes: .. code-block:: javascript { type: "Plot", id: 100032, attributes: { ... } } Typically the type name is inferred automatically from the Python class name, and is set as the ``__view_model__`` class attribute on the Model class that is create. But it is also possible to override this value explicitly: .. code-block:: python class Foo(Model): pass class Bar(Model): __view_model__ == "Quux" This metaclass will raise an error if two Bokeh models are created that attempt to have the same view model name. The only exception made is if one of the models has a custom ``__implementation__`` in its class definition. This metaclass also handles subtype relationships between Bokeh models. Occasionally it may be necessary for multiple class types on the Python side to resolve to the same type on the BokehJS side. This is called subtyping, and is expressed through a ``__subtype__`` class attribute on a model: .. code-block:: python class Foo(Model): pass class Bar(Foo): __view_model__ = "Foo" __subtype__ = "Bar" In this case, python instances of ``Foo`` and ``Bar`` will both resolve to ``Foo`` models in BokehJS. In the context of a Bokeh server application, the original python types will be faithfully round-tripped. (Without the ``__subtype__`` specified, the above code would raise an error due to duplicate view model names.) .. _metaclass: https://docs.python.org/3/reference/datamodel.html#metaclasses cC`s£d|kr||d (function() { var expanded = false; var ellipsis = document.getElementById("%(ellipsis_id)s"); ellipsis.addEventListener("click", function() { var rows = document.getElementsByClassName("%(cls_name)s"); for (var i = 0; i < rows.length; i++) { var el = rows[i]; el.style.display = expanded ?
