input multiple bytes for blocking or non-blocking processing
Implements BufferedTransformation. Definition at line 286 of file zinflate.cpp. References Inflator::m_inQueue, and Filter::Output(). |
|
Reimplemented from 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, InformationDispersal, Unflushable< Filter >, Unflushable< Multichannel< Filter > >, and Multichannel< Filter >. Definition at line 68 of file filters.cpp. References Filter::m_continueAt, and Filter::OutputFlush(). |
|
mark end of a series of messages There should be a MessageEnd immediately before MessageSeriesEnd. Reimplemented from BufferedTransformation. Reimplemented in Multichannel< Filter >. Definition at line 82 of file filters.cpp. References BufferedTransformation::IsolatedMessageSeriesEnd(), Filter::m_continueAt, Filter::OutputMessageSeriesEnd(), and Filter::ShouldPropagateMessageSeriesEnd(). |
|
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 716 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, OutputProxy, ArraySink, ArrayXorSink, ByteQueue, Multichannel< Filter >, and Multichannel< Sink >. Definition at line 735 of file cryptlib.h. Referenced by BufferedTransformation::ChannelCreatePutSpace(), and ArrayXorSink::CreatePutSpace(). |
|
input multiple bytes that may be modified by callee for blocking or non-blocking processing
Reimplemented in MeterFilter, FilterWithBufferedInput, OutputProxy, Multichannel< Filter >, and Multichannel< Sink >. Definition at line 753 of file cryptlib.h. Referenced by BufferedTransformation::ChannelPutModifiable2(), NetworkSource::GeneralPump2(), and Filter::OutputModifiable(). |
|
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, ByteQueue::Walker, and RandomPool. Definition at line 247 of file cryptlib.cpp. References BufferedTransformation::AttachedTransformation(), BufferedTransformation::CopyTo(), and BufferedTransformation::MaxRetrievable(). Referenced by RandomNumberStore::AnyRetrievable(), Integer::BERDecode(), Integer::Decode(), DL_GroupParameters_EC< EC >::Initialize(), BufferedTransformation::MaxRetrievable(), EcRecommendedParameters< ECP >::NewEC(), EcRecommendedParameters< EC2N >::NewEC(), Integer::OpenPGPDecode(), and BufferedTransformation::TotalBytesRetrievable(). |
|
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(), BufferedTransformation::AttachedTransformation(), and BufferedTransformation::GetNextMessage(). Referenced by BufferedTransformation::GetNextMessage(), and BufferedTransformation::TransferMessagesTo2(). |
|
wait on this object same as creating an empty container, calling GetWaitObjects(), and calling Wait() on the container Definition at line 321 of file wait.cpp. References Waitable::GetWaitObjects(), and WaitObjectContainer::Wait(). Referenced by NetworkSource::GeneralPump2(), and NetworkSink::TimedFlush(). |
