classmethod _convert_from(mod: GraphModuleBase) → GraphModuleBase

Convert another GraphModule to a GraphModule of this specific subclass

You should override this method in your subclass, to include conversion rules from other graph module classes to your specific subclass.

If you do not provide conversion rules to your specific subclass then it will not be possible to map other GraphModule subclasses to your subclass.

Parameters:: mod (GraphModule) – A GraphModule or GraphModule subclass object to convert to an object of the specific subclass.
Returns:: A converted GraphModule subclass object, of the specific subclass on which this method was called.
Return type:: GraphModule

classmethod _factory(size_in: int, size_out: int, name: str | None = None, computational_module: Any | None = None, *args, **kwargs) → GraphModuleBase

Build a new GraphModule or GraphModule subclass, with new input and output GraphNode s created automatically

Use this factory method to construct a new GraphModule from scratch, which needs new input and output GraphNode s created automatically. This helper method will be inherited by new GraphModule subclasses, and will act as factory methods also for your custom GraphModule subclass.

Parameters:

size_in (int) – The number of input GraphNode s to create and attach
size_out (int) – The number of output GraphNode s to create and attach
name (str, optional) – An arbitrary name to attach to this GraphModule, defaults to None
computational_module (Optional[Module], optional) – A rockpool computational module that forms the “generator” of this graph module, defaults to None

Returns:

The newly constructed GraphModule or GraphModule subclass

Return type:

GraphModuleBase

add_input(node: GraphNode) → None

Parameters:: node (GraphNode) – The node to add as an input source

add_output(node: GraphNode) → None

Add a GraphNode as an output of this module, and connect it

The new node will be appended after the last current output node. The node will be connected with this GraphModule as a source.

Parameters:: node (GraphNode) – The node to add as an output
