ewokscore.ppftasks.PpfMethodExecutorTask#

class ewokscore.ppftasks.PpfMethodExecutorTask(inputs=None, varinfo=None, node_id=None, node_attrs=None, execinfo=None, profile_directory=None)[source]#

Bases: Task

Ppf workflows pass one dictionary around between tasks and this dictionary gets updates by each task. This dictionary is unpacked into the unexpected arguments and passed to the method.

Parameters:

inputs (Optional[Mapping])
varinfo (Optional[dict])
node_id (Union[str, int, tuple, None])
node_attrs (Optional[dict])
execinfo (Optional[dict])
profile_directory (Optional[dict])
