on_hasattrs(→ Callable[[Any], List[bool]])	Get an object description function that checks whether an instance possesses
on_checks(→ Callable[[Any], List[bool]])	Get an object description function that runs a predefined set of checks (which
on_hasweights(→ Callable[[Any], List[bool]])	Check whether an objects has certain weights above a threshold in its weights
on_contains(→ Callable[[Any], List[bool]])	Check whether an object contains certain contents.

ragraph.analysis.similarity.utils.on_hasattrs(attrs: List[str]) → Callable[[Any], List[bool]]

Get an object description function that checks whether an instance possesses certain attributes. It does not check the values thereof!

Parameters:

attrs – List of attributes to check the existence of.

Returns:

Object description function indicating attribute possession.

ragraph.analysis.similarity.utils.on_checks(checks: List[Callable[[Any], bool]]) → Callable[[Any], List[bool]]

Get an object description function that runs a predefined set of checks (which should be in a fixed order) and returns their boolean results.

Parameters:

checks – Checks to perform.

Returns:

Object description function indicating check passings.

ragraph.analysis.similarity.utils.on_hasweights(weights: List[str], threshold: float = 0.0) → Callable[[Any], List[bool]]

Check whether an objects has certain weights above a threshold in its weights dictionary property.

Parameters:

• weights – Keys to the obj.weights dictionary to check.

• threshold – Threshold to verify against.

Returns:

Object description function indicating weights exceeding a threshold.

ragraph.analysis.similarity.utils.on_contains(contents: List[Any]) → Callable[[Any], List[bool]]

Check whether an object contains certain contents.

Parameters:

contents – Contents to check for with lambda x: x in obj.

Returns:

Object description function indicating content presence.
