Constructor Detail

NodeId

public NodeId(int port,
              InetAddress addr)

Construct a new NodeId.

Parameters:

port - The network port; must be between 0 and 65535 inclusive.

addr - The IP address

NodeId

public NodeId(String peer)
       throws NodeId.BadFormat,
              UnknownHostException

Read this NodeId in from a string of the same format as produced by toString (), below.

NodeId

public NodeId()

NodeId

public NodeId(InputBuffer buffer)
       throws QSException

Method Detail

serialize

public void serialize(OutputBuffer buffer)

Description copied from interface: QuickSerializable

Add the object to the buffer.

Specified by:

serialize in interface QuickSerializable

Parameters:

buffer - the output buffer to add the object to

address

public InetAddress address()

Return the InetAddress associated with this NodeId; does not work under the simulator.

JUST TO MAKE THAT CLEAR, THIS FUNCTION WILL NOT WORK IN THE OCEANSTORE SIMULATOR. YOU HAVE BEEN WARNED.

port

public int port()

toString

public String toString()

Overrides:

toString in class Object

compareTo

public int compareTo(Object other)

Specified by the Comparable interface.

Specified by:

compareTo in interface Comparable

equals

public boolean equals(Object other)

Overrides:

equals in class Object

less_than

public boolean less_than(NodeId other)

a.less_than (b) returns true iff a is less than b. Used for sorting NodeIds.

hashCode

public int hashCode()

Overrides:

hashCode in class Object

clone

public Object clone()
             throws CloneNotSupportedException

Create an exact copy of this NodeId

Overrides:

clone in class Object

Returns:

new NodeId identical in value to this one

Throws:

CloneNotSupportedException - if clone() is not supported
