Type aliases & semi-public classes¶
There are internally used classes and type aliases that can be of interest for re-use in applications and extensions.
Filter functions are defined as:
- delb.typing.Filter¶
alias of Callable[[NodeBase], bool]
Loaders are defined as:
- delb.typing.Loader¶
alias of Callable[[Any, SimpleNamespace], LoaderResult]
The order of loaders is defined with help of (read:
Loader | Iterable[Loader] | None):
- delb.typing.LoaderConstraint¶
alias of Loader | Iterable[Loader] | None
Loaders may return a string that explains why it wouldn’t successfully process the given input to the user:
- delb.typing.LoaderResult¶
alias of etree._ElementTree | str
Namespace to prefix mappings are formalized as:
- delb.typing.NamespaceDeclarations¶
alias of Mapping[str | None, str]
All node classes inherit from a common class:
- class delb.NodeBase¶
Methods that add nodes to a tree take a variety of input data:
- delb.typing.NodeSource¶
alias of str | NodeBase | _TagDefinition
Definitions that are used for convenient tree building are held in:
- class _delb.nodes._TagDefinition(local_name: str, attributes: dict[AttributeAccessor, str] | None = None, children: tuple[NodeSource, ...] = ())[source]¶
Instances of this class describe tag nodes that are constructed from the context they are used in (commonly additions to a tree) and the properties that this description holds. For the sake of slick code they are not instantiated directly, but with the
delb.tag()function.
