Method Detail

addTargetHost

protected boolean addTargetHost(Entity entity)
Adds this host, if it is absent or if its hostname has changed.

For whether to use hostname or ip, see config and attributes AbstractGeoDnsService#USE_HOSTNAMES#USE_HOSTNAMES, Attributes#HOSTNAME#HOSTNAME and Attributes#ADDRESS#ADDRESS (via inferHostname(Entity) and inferIp(Entity). Note that the "hostname" could in fact be an IP address, if inferHostname(Entity) returns an IP!

TODO in a future release, we may change this to explicitly set the sensor(s) to look at on the entity, and be stricter about using them in order.

Returns:
true if host is added or changed
