Detailed Description

Base class for computational nodes with inputs and outputs.

CodeNode represents any computational operation in the dataflow graph. It provides:

• Named input and output connectors
• Methods to query and modify connectors
• Detection of constant inputs
• Abstract cloning interface for graph transformations

Derived classes must implement:

• validate(): Validate the node's configuration
• clone(): Create a copy of the node
