Services.CorrelationsView.ScriptGeneration.Converter

public class Converter
extends Object

Handles the conversion of HAR files into JMeter JMX scripts using the BlazeMeter Converter public API.

The conversion workflow is:

1. Upload a HAR files
2. Trigger the conversion process
3. Poll conversion status until finished
4. Download the generated JMX file
5. Save it locally

This class acts as an HTTP client wrapper and orchestrator for the full conversion lifecycle.
