Method Details

resolveBindHostAddresses

public InetAddress[] resolveBindHostAddresses(String[] bindHosts)
                                       throws IOException

Resolves bindHosts to a list of internet addresses. The list will not contain duplicate addresses.

Parameters:

bindHosts - list of hosts to bind to. this may contain special pseudo-hostnames such as _local_ (see the documentation). if it is null, it will fall back to _local_

Returns:

unique set of internet addresses

Throws:

IOException

resolvePublishHostAddresses

public InetAddress resolvePublishHostAddresses(String[] publishHosts)
                                        throws IOException

Resolves publishHosts to a single publish address. The fact that it returns only one address is just a current limitation.

If publishHosts resolves to more than one address, then one is selected with magic

Parameters:

publishHosts - list of hosts to publish as. this may contain special pseudo-hostnames such as _local_ (see the documentation). if it is null, it will fall back to _local_

Returns:

single internet address

Throws:

IOException
