Method Detail

clone

public java.lang.Object clone()

Description copied from class: DrclObj

Returns a clone of this object. By default, this method creates an object of the same class and calls DrclObj.duplicate(Object) to duplicate the content of this object to the newly-created one.

This method uses getClass().newInstance() to create new instance. Hence, subclasses need to override this method only if the subclass is not declared as public or does not have explicit no-argument constructor. A subclass may override this method for performance reason.

Specified by:

clone in interface ObjectDuplicable

Overrides:

clone in class DrclObj

duplicate

public void duplicate(java.lang.Object source_)

Description copied from class: DrclObj

opies the content of the source_ object to this object. he subclass must implement this method to realize DrclObj.clone().

Specified by:

duplicate in interface ObjectDuplicable

Overrides:

duplicate in class DrclObj

get_hello_interval

protected int get_hello_interval()

get_router_dead_interval

protected int get_router_dead_interval()

set_neighbor_id

protected void set_neighbor_id(java.util.Vector list)

add_neighbor_id

protected void add_neighbor_id(int id)

size

protected int size()

return the packet length of Hello Body (in byte) , which excludes the OSPF header length Network Mask: 4, HelloInterval:2, Options:1, Rtr Pri:1, RouterDeadInterval: 4 Designated Router: 4, Backup: 4, the sum of the above items is assigned to FIX_HELLO_LEN = 20, Neighbor: each 4 byte
