cutcutcodec.core.compilation.tree_to_graph

Create the graph from an cutcutcodec.core.classes.node.Node.

Functions

`new_node`(graph, node)	Compiles a node in an existing assembly graph context.
`tree_to_graph`(container_out)	Create the graph from an implicit dynamic tree.

Details

cutcutcodec.core.compilation.tree_to_graph.new_node(graph: MultiDiGraph, node: Node) → tuple[str, dict[str]][source]

Compiles a node in an existing assembly graph context.

Parameters

graphnetworkx.MultiDiGraph: The graph on which we add the node.
nodecutcutcodec.core.classes.node.Node: The node that we want to name and extract properties.

Returns

namestr: The name of the node, this name is not already present in the graph.
attrsdict[str]: The attributes, the state of the node allowing to complete the graph.

Notes

The graph remains unchanged, it is only used for analysis.

cutcutcodec.core.compilation.tree_to_graph.tree_to_graph(container_out: Node) → MultiDiGraph[source]

Create the graph from an implicit dynamic tree.

The generated assembly graph abstracts and simplifies the modification of the pipeline. Gives a representation of the assembly tree in the form of a manipulable graph.

Parameters

container_outcutcutcodec.core.classes.node.Node: The output of the dynamic graph.

Returns

assembly_graphnetworkx.MultiDiGraph: The strictly equivalent assembly graph.
