Method Details

workflow

public StateGraph<ImageToDiagram.State> workflow()
                                          throws Exception

Generates a workflow graph using the StateGraph framework with specific nodes and conditional edges.

Returns:

A configured StateGraph instance representing the workflow.

Throws:

Exception - if an error occurs during the configuration of the graph.

workflowWithCorrection

public StateGraph<ImageToDiagram.State> workflowWithCorrection()
                                                        throws Exception

This method orchestrates a workflow for processing diagrams. It initializes a state graph and adds nodes and subgraphs to represent different stages of diagram correction and translation. The method also sets up conditional edges based on the type of diagram being translated.

Returns:

A StateGraph object representing the complete workflow diagram.

Throws:

Exception - if any errors occur during the setup of the workflow.

execute

public org.bsc.async.AsyncGenerator<NodeOutput<ImageToDiagram.State>> execute(@NonNull
 @NonNull ImageToDiagramProcess.ImageUrlOrData imageData)
                                                                       throws Exception

Executes the workflow using the provided image data and returns a stream of NodeOutput objects.

Parameters:

imageData - The image data to be processed, which must not be null.

Returns:

A stream of NodeOutput objects generated by the workflow.

Throws:

Exception - if an error occurs during execution.

executeWithCorrection

public org.bsc.async.AsyncGenerator<NodeOutput<ImageToDiagram.State>> executeWithCorrection(@NonNull
 @NonNull ImageToDiagramProcess.ImageUrlOrData imageData)
                                                                                     throws Exception

Executes the workflow with correction for the given image data.

Parameters:

imageData - The image data to process, cannot be null.

Returns:

An asynchronous generator of node outputs.

Throws:

Exception - If an error occurs during execution.
