      org.rhq.enterprise.communications.util.prefs.LocalInetHostnameSetupInstruction

public class LocalInetHostnameSetupInstruction
extends SetupInstruction

This setup instruction is used to define a preference whose value is a fully qualified hostname that is to be bound to the local host, but by default not the loopback device. This is used to allow a user to default the hostname to something other than the loopback device (localhost or 127.0.0.1) in order for clients external to this local box to connect to it.

                                  throws IllegalArgumentException

Creates a new LocalInetHostnameSetupInstruction object. This constructor is to allow an instruction to define a custom hostname whose default is the current preference's value. The default will not be the platform's actual FQDN.

Parameters:

preference_name -

prompt_message -

help_message -

validity_checker -

Throws:

IllegalArgumentException

Method Detail

preProcess

public void preProcess()

Sets the default as a hostname for this local host. We try not to set it to a loopback device, but if we have no choice, we do. We'll fallback to the current preference value if the default is GET_PREF_DEFAULT_MARKER.

Overrides:
