meshed.composition

Specific use of FuncNode and DAG

Functions

func_node_kwargs_trans(func)
func_node_name_trans(name_trans, *[, ...])
get_param(func)	Find the name of the parameter of a function with exactly one parameter.
is_func_node_kwargs_trans(func)	Returns True iff the only required params of func are FuncNode field names.
line_with_dag(*steps)	Emulate a Line object with a DAG
suffix_ids(func_nodes[, renamer, ...])

meshed.composition.func_node_name_trans(name_trans, *, also_apply_to_func_label=False)

Parameters:

• name_trans (Callable[[str], str | None]) – A function taking a str and returning a str, or None (to indicate that no transformation should take place).

• also_apply_to_func_label (bool)

Returns:

meshed.composition.get_param(func)

Find the name of the parameter of a function with exactly one parameter. Raise an error if more or less parameters.

Parameters:

func – callable, the function to inspect

Returns:

str, the name of the single parameter of func

meshed.composition.is_func_node_kwargs_trans(func)

Returns True iff the only required params of func are FuncNode field names. This ensures that the func will be able to be bound to FuncNode fields and therefore used as a func_node (kwargs) transformer.

Return type:

bool

meshed.composition.line_with_dag(*steps)

Emulate a Line object with a DAG

Parameters:

steps – an iterable of callables, the steps of the pipeline. Each step should have exactly one parameter and the output of each step is fed into the next

Returns:

a DAG instance computing the composition of all the functions in steps, in the provided order
