Method	Description
EntryCallback ( object o ) : void	If half of ttl time passed, this event handler is called. AlarmEventHandler calls "DhtClient.Put" command to insert the entry to other nodes. It restarts the timer. If error occurs during ASyncPut, it retries after 30 seconds

If the key,value pair does not exist in _entries, it creates the pair in the list. Otherwise, it updates the ttl. After inserting the entry, this module try to register the key, value pair to neighbor node.
RpcDhtProxy ( IDht dht, Node node ) : System	Initiates a RpcProxyHandler instance. It uses reflection for rpc call. Thus, it does not have to inherit IRpcHanler.This instance keeps Entry to keep track of key, value, and ttl
Unregister ( MemBlock key, MemBlock value ) : bool	Unregister the proxy entry. Removes the entry from Dictionary and set the stop the timer to disable future reference

Method Details

EntryCallback() public method

If half of ttl time passed, this event handler is called. AlarmEventHandler calls "DhtClient.Put" command to insert the entry to other nodes. It restarts the timer. If error occurs during ASyncPut, it retries after 30 seconds

public EntryCallback ( object o ) : void
o	object	Entry which initiates ttl time expire event
return	void

HandleRpc() public method

public HandleRpc ( ISender caller, string method, IList arguments, object request_state ) : void
caller	ISender
method	string
arguments	IList
request_state	object
return	void

ListEntries() public method

Returns all stored values in a list.

public ListEntries ( ) : object
return	object

Register() public method

This is a RpcDhtProxy rpc call entry, which can be called using "RpcDhtProxy.Register" Register the entry to Entry. If the key,value pair does not exist in _entries, it creates the pair in the list. Otherwise, it updates the ttl. After inserting the entry, this module try to register the key, value pair to neighbor node.

public Register ( MemBlock key, MemBlock value, int ttl ) : bool
key	MemBlock	dht entry key to insert
value	MemBlock	dht entry value to insert
ttl	int	dht entry ttl to insert
return	bool

RpcDhtProxy() public method

Initiates a RpcProxyHandler instance. It uses reflection for rpc call. Thus, it does not have to inherit IRpcHanler.This instance keeps Entry to keep track of key, value, and ttl

public RpcDhtProxy ( IDht dht, Node node ) : System
dht	IDht	IDht instance
node	Brunet.Node	node which is currently connected.
return	System

Unregister() public method

Unregister the proxy entry. Removes the entry from Dictionary and set the stop the timer to disable future reference

public Unregister ( MemBlock key, MemBlock value ) : bool
key	MemBlock
value	MemBlock
return	bool
