Class RevocationChecker

java.lang.Object

freenet.node.updater.RevocationChecker

All Implemented Interfaces:

ClientBaseCallback, ClientGetCallback, RequestClient

public class RevocationChecker
extends java.lang.Object
implements ClientGetCallback, RequestClient

Fetches the revocation key. Each time it starts, it will try to fetch it until it has 3 DNFs. If it ever finds it, it will be immediately fed to the NodeUpdateManager.

Constructor Detail

RevocationChecker

public RevocationChecker(NodeUpdateManager manager,
                         java.io.File blobFile)

Method Detail

getRevocationDNFCounter

public int getRevocationDNFCounter()

start

public void start(boolean aggressive)

start

public boolean start(boolean aggressive,
                     boolean reset)

Start a fetch.

Parameters:

aggressive - If set to true, then we have just fetched an update, and therefore can increase the priority of the fetch to maximum.

Returns:

True if the checker was already running and the counter was not reset.

onChangeRevocationURI

public void onChangeRevocationURI()

Called when the revocation URI changes.

onSuccess

public void onSuccess(FetchResult result,
                      ClientGetter state)

Description copied from interface: ClientGetCallback

Called on successful fetch. Caller should schedule a job on the Ticker or Executor (on the ClientContext) if it needs to do much work.

Specified by:

onSuccess in interface ClientGetCallback

hasBlown

public boolean hasBlown()

onFailure

public void onFailure(FetchException e,
                      ClientGetter state)

Description copied from interface: ClientGetCallback

Called on failed/canceled fetch. Caller should schedule a job on the Ticker or Executor (on the ClientContext) if it needs to do much work.

Specified by:

onFailure in interface ClientGetCallback

kill

public void kill()

getBlobSize

public long getBlobSize()

getBlobBucket

public RandomAccessBucket getBlobBucket()

getBlobBuffer

public RandomAccessBuffer getBlobBuffer()

persistent

public boolean persistent()

Description copied from interface: RequestClient

Is this request persistent? **Must not change!**

Specified by:

persistent in interface RequestClient

realTimeFlag

public boolean realTimeFlag()

Description copied from interface: RequestClient

Send the request with the real time flag enabled? Real-time requests are given a higher priority in data transfers, but fewer of them are accepted. They are optimised for latency rather than throughput, and are expected to be bursty rather than continual. **Must not change!**

Specified by:

realTimeFlag in interface RequestClient

onResume

public void onResume(ClientContext context)

Description copied from interface: ClientBaseCallback

Called for a persistent request when the node is restarted. Must re-register with whatever infrastructure the request is using, e.g. PersistentRequestRoot, persistent temp buckets etc.

Specified by:

onResume in interface ClientBaseCallback

getRequestClient

public RequestClient getRequestClient()

Description copied from interface: ClientBaseCallback

Get the RequestClient context object used to indicate which requests are related to each other for scheduling purposes.

Specified by:

getRequestClient in interface ClientBaseCallback
