# API Reference Generated Javadoc for the public Java API lives at api/index.html. The reference covers the `org.apache.datafusion` package, including `SessionContext`, `SessionContextBuilder`, `DataFrame`, `CsvReadOptions`, `ParquetReadOptions`, and `NativeLibraryLoader`, plus the `org.apache.datafusion.proto` helpers. Auto-generated protobuf classes are intentionally excluded from the Javadoc — they are an implementation detail.
