Метод Описание
AddEntry ( Entry entry ) : void

This adds an entry and should only be called if no such entry exists, as it does not look to see if a duplicate entry already exists. This creates a new LinkedList if this is the first entry for the specific key and stores it in the _data hashtable. This increments count.

Because data is stored by non-decreasing end time, we must place this at the correct position, which by starting at the last entry is right after the first entry that has a shorter end time.

CacheEviction ( Object o, EventArgs args ) : void
CacheMiss ( Object o, EventArgs args ) : void
CheckEntries ( ) : void

Deletes any of the expired entries by traversing the entire data store. This is done only once every 24 hours to reduce heavy memory access due to short lived unused entries.
CleanUp ( Object o, EventArgs args ) : void

Called to clean up the disk data left behind by the dht
DeleteExpired ( MemBlock key ) : int

Deletes all expired entries for the specified key. For each entry deleted, count is decremented. This should be called before accessing the data stored in this table.
Dump ( ) : ArrayList

Converts all the entries into Adr compatible types so that they can be sent over BrunetRpc and XmlRpc
GeneratePath ( MemBlock key ) : string

Generates a path given a key.
GeneratePath ( MemBlock key, string &path, string &filename ) : string

Generates a path given a key.
GetEntries ( MemBlock key ) : LinkedList

Retrieves the entries for the specified key.
GetKeys ( ) : LinkedList

Returns the list of keys.
GetKeysBetween ( AHAddress add1, AHAddress add2 ) : LinkedList

Returns a list of keys stored at this node that exist between the two addresses. Such keys returned are the storest path between the two addresses.
RemoveEntry ( MemBlock key, MemBlock value ) : void

This removes an entry from the TableServerData, the current dht does not support deletes, but if the second stage of a put (the remote PutHandler) fails, the entry needs to be deleted from this node.
TableServerData ( ) : System
TableServerData ( Node node ) : System

Creates a new data store for the dht.
TableServerData ( String dir ) : System
UpdateEntry ( MemBlock key, MemBlock value, DateTime end_time ) : void

This should be called if an entry already exists as it will find the entry and update its lease time. If an entry does not exist nothing happens.
