Represents a processor of simulation data.

A processor that never finishes its work producing an emptyStream.

Create a simple processor by the specified handling function that runs the discontinuous process for each input value to get the output.

Accumulator that outputs a value determined by the supplied function.

Create a processor that will use the specified process identifier. It can be useful to refer to the underlying Process computation which can be passivated, interrupted, canceled and so on. See also the processUsingId function for more details.

This is a prefetch processor that requests for one more data item from the input in advance while the latest item is not yet fully processed in the chain of streams, usually by other processors.

You can think of this as the prefetched processor could place its latest data item in some temporary space for later use, which is very useful for modeling a sequence of separate and independent work places.

A processor that delays the input stream by one step using the specified initial value.

Create a buffer processor, where the process from the first argument consumes the input stream but the stream passed in as the second argument and produced usually by some other process is returned as an output. This kind of processor is very useful for modeling the queues.

Like bufferProcessor but allows creating a loop when some items can be processed repeatedly. It is very useful for modeling the processors with queues and loop-backs.

Return a processor with help of which we can model the queue.

Although the function doesn't refer to the queue directly, its main use case is namely a processing of the queue. The first argument should be the enqueueing operation, while the second argument should be the opposite dequeueing operation.

The reason is as follows. There are many possible combinations how the queues can be modeled. There is no sense to enumerate all them creating a separate function for each case. We can just use combinators to define exactly what we need.

So, the queue can lose the input items if the queue is full, or the input process can suspend while the queue is full, or we can use priorities for enqueueing, storing and dequeueing the items in different combinations. There are so many use cases!

There is a hope that this function along with other similar functions from this module is sufficient to cover the most important cases. Even if it is not sufficient then you can use a more generic function bufferProcessor which this function is based on. In case of need, you can even write your own function from scratch. It is quite easy actually.

Like queueProcessor creates a queue processor but with a loop when some items can be processed and then added to the queue again. Also it allows specifying how two input streams of data can be merged.

Like queueProcessorLoopMerging creates a queue processor with a loop when some items can be processed and then added to the queue again. Only it sequentially merges two input streams of data: one stream that come from the external source and another stream of data returned by the loop. The first stream has a priority over the second one.

Like queueProcessorLoopMerging creates a queue processor with a loop when some items can be processed and then added to the queue again. Only it runs two simultaneous processes to enqueue the input streams of data: one stream that come from the external source and another stream of data returned by the loop.

Launches the processors sequentially using the prefetchProcessor between them to model an autonomous work of each of the processors specified.

Launches the processors in parallel consuming the same input stream and producing a combined output stream. This version applies the FCFS strategy both for input and output, which suits the most part of uses cases.

Launches the specified processors in parallel consuming the same input stream and producing a combined output stream.

If you don't know what the enqueue strategies to apply, then you will probably need FCFS for the both parameters, or function processorParallel that does namely this.

Launches the specified processors in parallel using priorities for combining the output.

Launches the specified processors in parallel using priorities for consuming the intput.

Launches the specified processors in parallel using priorities for consuming the input and combining the output.

A processor that adds the information about the time points at which the original stream items were received by demand.

Convert the specified signal transform to a processor.

The processor may return data with delay as the values are requested by demand. Consider using the arrivalSignal function to provide with the information about the time points at which the signal was actually triggered.

The point is that the Stream used in the Processor is requested outside, while the Signal is triggered inside. They are different by nature. The former is passive, while the latter is active.

Cancel the processor's process to unsubscribe from the signals provided.
