Constructor Details

StaticHostProvider

public StaticHostProvider(Collection<InetSocketAddress> serverAddresses)

Constructs a SimpleHostSet.

Parameters:

serverAddresses - possibly unresolved ZooKeeper server addresses

Throws:

IllegalArgumentException - if serverAddresses is empty or resolves to an empty list

StaticHostProvider

public StaticHostProvider(Collection<InetSocketAddress> serverAddresses,
 StaticHostProvider.Resolver resolver)

Introduced for testing purposes. getAllByName() is a static method of InetAddress, therefore cannot be easily mocked. By abstraction of Resolver interface we can easily inject a mocked implementation in tests.

Parameters:

serverAddresses - possibly unresolved ZooKeeper server addresses

resolver - custom resolver implementation

Throws:

IllegalArgumentException - if serverAddresses is empty or resolves to an empty list
