Dataset Accessors

PyVista exposes a pandas/xarray-style accessor mechanism so that third-party packages can add namespaced filter methods to dataset classes without monkey-patching or subclassing. Once a plugin module is imported, its accessor becomes available on every instance of the target class as dataset.<namespace>.<method>(...) and chains seamlessly with built-in PyVista filters.

See Extending PyVista for a full guide with a worked example and guidance on typing and autocomplete.

register_dataset_accessor(name, target_cls, *)	Register a custom namespaced accessor on a PyVista dataset class.
