Node Base Classes

class mh_en_exec.nodes.NodeBase(id_, name='Node Base')

The NodeBase class is the base class for the nodes To create external node, need to inherit this class and implement perform function

perform(*args, **kwargs) → tuple

This function is called when a node is executed on the Machine Heads side.

Input port values will be set as arguments of this function.

Output port values need to be set as a return values of this function.

Return type:

In case of data node: tuple[{output port values}]

In case of action node: bool, tuple[{output port values}]

first value of the action node return values is a bool value. If `True` `out_on_success` port will be called, if `False` `out_on_failure` port will be called

Raises

NotImplementedError – In case of function is not overrode
