Method Detail

getIpAddress

public final java.net.InetAddress getIpAddress()

getPort

public final int getPort()

isMulticastAddress

public final boolean isMulticastAddress()
Description copied from interface: Address
Checks whether this is an address that represents multiple destinations; e.g., a class D address in the Internet.

Specified by:
isMulticastAddress in interface Address
Returns:
true if this is a multicast address, false if it is a unicast address

getAdditionalData

public final byte[] getAdditionalData()
Returns the additional_data.

Returns:
byte[]

setAdditionalData

public final void setAdditionalData(byte[] additional_data)
Sets the additional_data.

Parameters:
additional_data - The additional_data to set

compare

public final int compare(IpAddress other)
Establishes an order between 2 addresses. Assumes other contains non-null IpAddress. Excludes channel_name from comparison.

Returns:
0 for equality, value less than 0 if smaller, greater than 0 if greater.

compareTo

public final int compareTo(java.lang.Object o)
implements the java.lang.Comparable interface

Specified by:
compareTo in interface java.lang.Comparable
Parameters:
o - - the Object to be compared
Returns:
a negative integer, zero, or a positive integer as this object is less than, equal to, or greater than the specified object.
Throws:
java.lang.ClassCastException - - if the specified object's type prevents it from being compared to this Object.
