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.

AddEntry() 공개 메소드

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.

public AddEntry ( Entry entry ) : void
entry	Entry	The data to store.
리턴	void

CacheEviction() 공개 메소드

public CacheEviction ( Object o, EventArgs args ) : void
o	Object
args	System.EventArgs
리턴	void

CacheMiss() 공개 메소드

public CacheMiss ( Object o, EventArgs args ) : void
o	Object
args	System.EventArgs
리턴	void

CheckEntries() 공개 메소드

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.

public CheckEntries ( ) : void
리턴	void

CleanUp() 공개 메소드

Called to clean up the disk data left behind by the dht

public CleanUp ( Object o, EventArgs args ) : void
o	Object	Unused.
args	System.EventArgs	Unused.
리턴	void

DeleteExpired() 공개 메소드

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.

public DeleteExpired ( MemBlock key ) : int
key	Brunet.Util.MemBlock	The index to check for expired entries.
리턴	int

Dump() 공개 메소드

Converts all the entries into Adr compatible types so that they can be sent over BrunetRpc and XmlRpc

public Dump ( ) : ArrayList
리턴	System.Collections.ArrayList

GeneratePath() 공개 메소드

Generates a path given a key.

public GeneratePath ( MemBlock key ) : string
key	MemBlock	The key to generate a path for.
리턴	string

GeneratePath() 공개 메소드

Generates a path given a key.

public GeneratePath ( MemBlock key, string &path, string &filename ) : string
key	MemBlock	The key to generate a path for.
path	string	Returns the directory portion of the path.

GetKeys() 공개 메소드

Returns the list of keys.

public GetKeys ( ) : LinkedList
리턴	LinkedList

GetKeysBetween() 공개 메소드

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.

public GetKeysBetween ( AHAddress add1, AHAddress add2 ) : LinkedList
add1	AHAddress	One of the address end points.
add2	AHAddress	Another of the address end points.
리턴	LinkedList

RemoveEntry() 공개 메소드

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.
