Package com.yahoo.net

Class HostName

java.lang.Object

ai.vespa.validation.StringWrapper<T>

ai.vespa.validation.PatternedStringWrapper<HostName>

com.yahoo.net.HostName

All Implemented Interfaces:

Comparable<HostName>

public class HostName
extends PatternedStringWrapper<HostName>

Hostnames match DomainName.domainNamePattern, but are restricted to 64 characters in length. This class also has utilities for getting the hostname of the system running the JVM. Detection of the hostname is now done before starting any Vespa programs and provided in the environment variable VESPA_HOSTNAME; if that variable isn't set a default of "localhost" is always returned.
