Class FieldMappingEngine

java.lang.Object

ecmwf.common.parser.mapping.FieldMappingEngine

public class FieldMappingEngine
extends Object

FieldMappingEngine is responsible for inferring how raw input fields map to FileEntry attributes.

It supports multiple formats:

• CSV (column-based inference)
• JSON (field/path-based inference)
• STAC (semantic JSON structure)
• XML (node path inference)

This engine does NOT parse data itself; it only analyzes structure and produces a MappingSuggestion.
