---|---|
void |
cancel(ClientContext context)
Cancel the request.
|
protected ClientBaseCallback |
getCallback() |
FreenetURI |
getURI()
Get the URI for the request or insert.
|
protected void |
innerNotifyClients(ClientContext context)
Notify clients, usually via a SplitfileProgressEvent, of the current progress.
|
void |
innerOnResume(ClientContext context)
Called by onResume() once and only once after restarting.
|
protected void |
innerToNetwork(ClientContext context)
Notify clients that a request has gone to the network, for the first time, i.e.
|
boolean |
isFinished()
Is the request or insert completed (succeeded, failed, or
cancelled, which is a kind of failure)?
|
void |
onBlockSetFinished(ClientGetState state,
ClientContext context)
Called when the ClientGetState knows that it knows about
all the blocks it will need to fetch.
|
void |
onExpectedMIME(ClientMetadata meta,
ClientContext context)
Called when we know the MIME type of the final data.
|
void |
onExpectedSize(long size,
ClientContext context)
Called when we know the size of the final data.
|
void |
onExpectedTopSize(long size,
long compressed,
int blocksReq,
int blocksTotal,
ClientContext context)
Called when we know the size of the final file, and the number of blocks needed etc.
|
void |
onFailure(FetchException e,
ClientGetState state,
ClientContext context) |
void |
onFinalizedMetadata() |
void |
onHashes(HashResult[] hashes,
ClientContext context)
Called when we know the HashResult of the final file.
|
void |
onSplitfileCompatibilityMode(InsertContext.CompatibilityMode min,
InsertContext.CompatibilityMode max,
byte[] splitfileKey,
boolean compressed,
boolean bottomLayer,
boolean definitiveAnyway,
ClientContext context)
Called when we know the settings for the splitfile.
|
void |

java.util.List<? extends Compressor> decompressors,
ClientGetState state,
ClientContext context) |
void |
onTransition(ClientGetState oldState,
ClientGetState newState,
ClientContext context)
Called when the ClientGetState handling the request yields control to another
ClientGetState.

meta
- The MIME type, possibly including parameters, as a String.

min
- The lowest CompatibilityMode that appears to be valid based on what we've fetched so far.max
- The highest CompatibilityMode that appears to be valid based on what we've fetched so far.splitfileKey
- The fixed byte[] encryption key used on insert. On anything recent, we generate a single key, randomly for an SSK,
or based on the content for a CHK, and use it for everything. This saves metadata space and improves security for SSKs.compressed
- Whether the content is compressed. If false, the dontCompress option was used.bottomLayer
- Whether this report originates at the bottom layer of the splitfile pyramid. I.e. the actual file, not the file containing
the metadata to fetch the file (this can recurse for several levels!)definitiveAnyway
- Whether this report is definitive even though it's not from the bottom layer. This is true of recent splitfiles,
where we store all the data in the top key.context

- A set of hashes for the final file content.context
