## Development Workflow

### Build Commands

```bash
mvn clean install              # Build all

        NdrHyper decoded = new NdrHyper(0);
        decoded.decode(buf);
        assertEquals(original, decoded.value, "Decoded value should match encoded value");

## Language Detection and Selection

### User Interface Language

Fess determines the UI language in this order:

- **SMB 3.0.2**: Windows 8.1/Server 2012R2 (0x0302) - Enhanced encryption
- **SMB 3.1.1**: Windows 10/Server 2016+ (0x0311) - AES-128-GCM + Pre-Auth Integrity

**Protocol Selection:**
- Default Range: SMB1 to SMB 3.1.1
- Automatic Negotiation: Client offers all supported dialects, server selects highest common version
- Configurable: Min/max versions can be set via configuration properties

 * This class implements AutoCloseable to properly handle resource cleanup.

 * <p>The factory maintains a map of regular expression patterns to crawler clients,
 * allowing for URL-based client selection. Clients can be added with specific patterns
 * and optionally at specific positions in the processing order.</p>
 *
 * <p>This factory is typically initialized through dependency injection and can be

 * for configuring the extraction parameters and handling the underlying complexities of content processing,
 * such as MIME type detection, extractor selection, and content length validation.
