Constructor Detail

UDPAddress

public UDPAddress()

Default constructor

UDPAddress

public UDPAddress(java.net.InetAddress addr,
                  int port)

Full constructor

Parameters:

addr - The InetAddress to use for this address.

port - The port to use for this address.

Method Detail

equals

public boolean equals(java.lang.Object other)

Compares two instances and returns true if they should be considered "equal". We require this function so that UDPAddresses hash correctly.

Parameters:

other - The Object to which we are being compared.

Returns:

Returns true if both objects are UDPAddresses with the same hostAddr and hostPort. Returns false otherwise.

Overrides:

equals in class java.lang.Object

hashCode

public int hashCode()

Returns the hashCode for this instace. We require this function so that UDPAddresses hash properly.

Overrides:

hashCode in class java.lang.Object

toString

public java.lang.String toString()

The canoncial toString method.

Overrides:

toString in class java.lang.Object

writeExternal

public void writeExternal(java.io.ObjectOutput out)
                   throws java.io.IOException

Serialize the contents of this class to the output stream.

Specified by:

writeExternal in interface java.io.Externalizable

Parameters:

out - The OutputStream to which we should write this instance.

readExternal

public void readExternal(java.io.ObjectInput in)
                  throws java.io.IOException,
                         java.lang.ClassNotFoundException

Deserialize into a new instnace of UDPAddress by reading from the given input stream.

Specified by:

readExternal in interface java.io.Externalizable

Parameters:

in - The InputStream from which we should deserialize this instance.

Throws:

java.io.IOException - Thrown if an I/O error is encountered while reading the input stream.

java.lang.ClassNotFoundException - Thrown if a class being deserialized from the input stream cannot be found by the class loader.

java.lang.ClassCastException - Thrown if a class deserialized from the input stream had an unexpected type.
