def add(path: String, address: InetSocketAddress): Future[Option[SetDataResponse]]

This has the effect of pushing a new InetSocketAddress or its string representation to be price to the set already in ZooKeeper.
This has the effect of pushing a new InetSocketAddress or its string representation to be price to the set already in ZooKeeper. A read operation is always performed first to avoid maintaining any state of the client side.
If the data is not available in the data that was read, a write operation is carried out. If the data is already there, the write operation is skipped to save time and bandwidth a Future is immediately completed.
path
The ZooKeeper path to add the address to.
address
A Future wrapping an optional operation response. If the address is already in the set no write operation is performed.

def hosts(path: String): Future[Set[InetSocketAddress]]

This method is shorthand syntax for retrieving the entire set of host:port pairs available on a ZooKeeper node.
This method is shorthand syntax for retrieving the entire set of host:port pairs available on a ZooKeeper node. It's used in conjunction with the default parsing convention defined.
path
The ZooKeeper path to read from.
returns
A set of unique host:port combinations represented as a set of InetSocketAddress objects.

def localAddress(port: Int): InetSocketAddress

This is a simple shorthand method allowing users to get a reference to the hostname of the current machine.
This is a simple shorthand method allowing users to get a reference to the hostname of the current machine. The purpose of this is to allow shorthand syntax for things like server.add(localAddress(somePort)){code}, effectively allowing applications to register as active and become discoverable via ZooKeeper.
port
The port to use in conjunction with the hostname of the current machine.
returns
An InetSocketAddress matching the hostname of the current machine and a chosen port.

def parse(data: String): Set[InetSocketAddress]

This method is used to parse the string of data obtained from a ZooKeeper path into a sequence of ports.
This method is used to parse the string of data obtained from a ZooKeeper path into a sequence of ports. It's highly opinionated about the format in which teh data should be and it will only work with our default.
Our format is "host:port*".
data
The data string fetched from ZooKeeper.

def register(path: String, data: String): Future[SetDataResponse]

This is a shorthand method for a UTF-8 based write operation to a ZooKeeper path.
This is a shorthand method for a UTF-8 based write operation to a ZooKeeper path. It will simply overwrite the existing data on a path with the argument provided.
The encoding in use by this method is always UTF 8.
path
The ZooKeeper path to write to.
data
The string of data to write to the ZooKeeper path.
returns
A Future wrapping the response of the write operation.

def register(path: String, address: Set[InetSocketAddress]): Future[SetDataResponse]

Registers a new set of addresses on a ZooKeeper node.
Registers a new set of addresses on a ZooKeeper node. This will overwrite any existing data on the path.
path
The ZooKeeper path to write to.
address
The InetSocketAddress to save as a sequence.
returns
A Future wrapping the response of the write operation.

def register(path: String, address: InetSocketAddress): Future[SetDataResponse]

Registers a address on a ZooKeeper node.
Registers a address on a ZooKeeper node. This will overwrite any existing data on the path.
path
The ZooKeeper path to write to.
address
The InetSocketAddress to save as a sequence.
returns

def remove(path: String, address: InetSocketAddress): Future[Option[SetDataResponse]]

This will remove an address from a ZooKeeper node/path.
This will remove an address from a ZooKeeper node/path. This is useful when a server is going out of service or any other similar situation.
A read operation is always carried out no matter what to avoid maintaining any state of the client side. If the address to be removed is not found in the existing set, no write operation will be carried out.
path
The ZooKeeper path to write to.
address
The InetSocketAddress to remove from the existing set.
returns
A Future wrapping an optional operation response. If the address is not in the set no write operation is performed.
