 org.jgroups.stack.LogicalAddress
| LogicalAddress | | public class LogicalAddress implements Address(Code) | | Logical address that spans the lifetime of a member. Assigned at member (JVM) startup, and
retained until member is shutdown. Note that the address does not change on
disconnect-connect sequences. For example, when a member is shunned and subsequently
readmitted to the group, the member's address (LogicalAddress) remains the same.
An instance of LogicalAddress is generated by the transport protocol. Currently, only
UDP_NIO generates LogicalAddresses.
Note that host, timestamp and id are supposed to make LogicalAddress as unique as possible.
However, there is a remote chance that 2 instances started on the same machine create their
address at exactly the same time, resulting in identical addresses (leading to problems).
In the future, I will try to make this totally unique, by for example using the PID of the current
process (once available though the JDK, or by locking on a common resource (e.g. /dev/random)
to serialize creation. However, as for now, chances are you will never experience this problem.

| additional_data | | byte[] additional_data(Code) | | To tack on some additional data
|
| count | | protected static int count(Code) | | |
| multicast_addr | | protected boolean multicast_addr(Code) | | |
| physical_addrs | | protected ArrayList physical_addrs(Code) | | List of physical addresses
|
| primary_physical_addr | | transient SocketAddress primary_physical_addr(Code) | | Address of the primary physical address. This is set to the sender when a message is received.
If this field is set, we will send unicast messages only to this address, not to all addresses listed
in physical_addrs; this reduces the number of msgs we have to send.
Note that this field is not shipped across the wire.

| timestamp | | protected long timestamp(Code) | | |
| LogicalAddress | | public LogicalAddress()(Code) | | |
| LogicalAddress | | public LogicalAddress(String host_name, List physical_addrs)(Code) | | Use this constructor to create an instance, not the null-constructor
|
| addPhysicalAddress | | public void addPhysicalAddress(SocketAddress addr)(Code) | | For internal use only. Don't use this method!
Parameters:
addr - |
| compare | | public int compare(LogicalAddress other)(Code) | | Establishes an order between 2 addresses. Assumes other contains non-null IpAddress.
Excludes channel_name from comparison.
0 for equality, value less than 0 if smaller, greater than 0 if greater. |
| compareTo | | public int compareTo(Object o)(Code) | | implements the java.lang.Comparable interface
See Also: Comparable
Parameters:
o - - the Object to be compared a negative integer, zero, or a positive integer as this object is less than,equal to, or greater than the specified object.
exception:
ClassCastException - - if the specified object's type prevents itfrom being compared to this Object. |
| getAdditionalData | | public byte[] getAdditionalData()(Code) | | Returns the additional_data.
byte[] |
| getId | | public long getId()(Code) | | |
| getPhysicalAddresses | | public ArrayList getPhysicalAddresses()(Code) | | Returns a copy of the list of physical addresses. Reason for the copy is that the list is not supposed
to be modified (should be immutable).

Parameters:
addr - |
