BufferedTransformation& BufferedTransformation::Ref | ( | ) | [inline, inherited] |
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.

void BufferedTransformation::GetWaitObjects | ( | WaitObjectContainer & | container, | |
CallStack const & | callStack | |||

Implements Waitable.

virtual void BufferedTransformation::SetAutoSignalPropagation | ( | int | propagation | ) | [inline, virtual, inherited] |
set propagation of automatically generated and transferred signals
propagation == 0 means do not automaticly generate signals

lword BufferedTransformation::MaxRetrievable | ( | ) | const [virtual, inherited] |
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 ByteQueue::Walker.

bool BufferedTransformation::GetNextMessage | ( | ) | [virtual, inherited] |
start retrieving the next message
Returns false if no more messages exist or this message is not completely retrieved.
Reimplemented in MessageQueue, and Store.

virtual bool BufferedTransformation::Attachable | ( | ) | [inline, virtual, inherited] |
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 in Filter.

bool Waitable::Wait | ( | unsigned long | milliseconds, | |
CallStack const & | callStack | |||
) | [inherited] |
wait on this object
same as creating an empty container, calling GetWaitObjects(), and calling Wait() on the container
