Method Details

next

public InetSocketAddress next()

Description copied from interface: DnsServerAddressStream

Retrieves the next DNS server address from the stream.

Specified by:

next in interface DnsServerAddressStream

duplicate

public DnsServerAddressStream duplicate()

Description copied from interface: DnsServerAddressStream

Duplicate this object. The result of this should be able to be independently iterated over via DnsServerAddressStream.next().

Note that #clone() isn't used because it may make sense for some implementations to have the following relationship x.duplicate() == x.

Specified by:

duplicate in interface DnsServerAddressStream

Returns:

A duplicate of this object.

size

public int size()

Description copied from interface: DnsServerAddressStream

Get the number of times DnsServerAddressStream.next() will return a distinct element before repeating or terminating.

Specified by:

size in interface DnsServerAddressStream

Returns:

the number of times DnsServerAddressStream.next() will return a distinct element before repeating or terminating.
