Method Detail

resolveBindHostAddresses

public java.net.InetAddress[] resolveBindHostAddresses(java.lang.String[] bindHosts)
                                                throws java.io.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 be populated based on global default settings.

Returns:

unique set of internet addresses

Throws:

java.io.IOException

resolvePublishHostAddresses

public java.net.InetAddress resolvePublishHostAddresses(java.lang.String[] publishHosts)
                                                 throws java.io.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 be populated based on global default settings.

Returns:

single internet address

Throws:

java.io.IOException
