SingleFileNamingService (I2P Anonymous Network - Java Documentation

java.lang.Object
- net.i2p.client.naming.NamingService
- - net.i2p.client.naming.SingleFileNamingService

```
public class SingleFileNamingService
extends NamingService
```
A naming service based on a single file using the "hosts.txt" format. Supports adds, removes, and listeners. All methods here are case-sensitive. Conversion to lower case is done in HostsTxtNamingService. This does NOT provide .b32.i2p or {b64} resolution. It also does not do any caching. Use from HostsTxtNamingService or chain with another NamingService via MetaNamingService if you need those features.

導入されたバージョン:

0.8.7
