GraphProcessor

Overview

The GraphProcessor class is an abstract base class for processing edges in the MultiDiGraph. This class provides a framework for adding new edges of some specified type to the graph. As an abstract base class, GraphProcessor can’t be directly instantiated. It must be subclassed, and its process method must be overwritten.

Method details

The GraphProcessor provides the following method:

process(): An abstract method that subclasses must override. When called, it adds new edges of the specified type to the graph.

Usage Example

Assuming an implementation of the GraphProcessor process method that adds edges defined by the ‘contains’ relationship between nodes, a usage example could be:

from networkx import MultiDiGraph
from automata.symbol.graph._ReferenceProcessor import ReferenceProcessor

graph = MultiDiGraph()
graph_processor = ReferenceProcessor(graph, document)
graph_processor.process()

In this example, _ReferenceProcessor is a concrete class inheriting from GraphProcessor that adds reference relationship edges to the graph.

Limitations

Because the GraphProcessor is an abstract base class, it cannot be used directly to protect the MultiDiGraph. A specific subclass of GraphProcessor must implement the process method to provide practical functionality.
