pump up to maxSize bytes using at most maxTime milliseconds If checkDelimiter is true, pump up to delimiter, which itself is not extracted or pumped. Implements NonblockingSource. Definition at line 57 of file network.cpp. References Filter::AttachedTransformation(), TimerBase::ElapsedTime(), NetworkReceiver::EofReceived(), NetworkReceiver::GetReceiveResult(), INFINITE_TIME, NetworkReceiver::MustWaitForResult(), NetworkReceiver::MustWaitToReceive(), NetworkReceiver::Receive(), SecBlock< T, A >::size(), and Waitable::Wait(). |

Reimplemented from BufferedTransformation. |
|
Implements BufferedTransformation. |
|
returns whether this object allows attachment Some BufferedTransformation objects (e.g. Filter objects) allow other BufferedTransformation objects to be attached. When this is done, the first object instead of buffering its output, sents that output to the attached object as input. The entire attachment chain is deleted when the anchor object is destructed. Reimplemented from BufferedTransformation. |
|
flush buffered input and/or output
Reimplemented from BufferedTransformation.
Reimplemented in SecretSharing, and InformationDispersal. Definition at line 68 of file filters.cpp. |
|
mark end of a series of messages There should be a MessageEnd immediately before MessageSeriesEnd. Reimplemented from BufferedTransformation. Definition at line 82 of file filters.cpp. |
|
return a reference to this object This function is useful for passing a temporary BufferedTransformation object to a function that takes a non-const reference. Definition at line 711 of file cryptlib.h. |
|
request space which can be written into by the caller, and then used as input to Put()
Reimplemented in MeterFilter, HashFilter, Redirector, ArraySink, ArrayXorSink, and ByteQueue. Definition at line 730 of file cryptlib.h. Referenced by ArrayXorSink::CreatePutSpace(). |
|
input multiple bytes that may be modified by callee for blocking or non-blocking processing
Reimplemented in MeterFilter, and FilterWithBufferedInput. Definition at line 748 of file cryptlib.h. |
|
returns number of bytes that is currently ready for retrieval All retrieval functions return the actual number of bytes retrieved, which is the lesser of the request number and MaxRetrievable(). Reimplemented in FileStore, RandomNumberStore, NullStore, MessageQueue, ByteQueue, and RandomPool. Definition at line 247 of file cryptlib.cpp. References BufferedTransformation::AttachedTransformation(), and BufferedTransformation::CopyTo(). Referenced by RandomNumberStore::AnyRetrievable(), and Integer::BERDecode(). |
|
start retrieving the next message Returns false if no more messages exist or this message is not completely retrieved. Reimplemented in MessageQueue, and Store. Definition at line 336 of file cryptlib.cpp. References BufferedTransformation::AnyMessages(), and BufferedTransformation::AttachedTransformation(). |
