csp::common Namespace Reference

Detailed Description

A namespace containing all the commonly used simple processes, such as Id.

These processes are commonly used to plumb/plug/glue together your network.

Many of the processes seem to do similar things to each other, and in fact certain combinations of processes are equivalent to other arrangements:

• N Id processes joined by unbuffered channels are equivalent to a buffered channel using a FIFOBuffer of size N. The FIFOBuffer is far more efficient.
• N ExtId processes joined by unbuffered channels are equivalent to one ExtId process. Naturally, using only one process is more efficient. In fact, one ExtId process is effectively equivalent to having no process at all -- but it is useful for joining two channels that cannot easily be turned into one channel.
• An ExtMerger process with unbuffered channels is equivalent to using an Any2OneChannel.

Putting an ExtId process to connect two channels has no effect on the synchronization. This can be used to your advantage. For example, you may find yourself wanting to use a Merger on two channels, but the input channels to it are One2AnyChannel, which do not support alting. If you connect each One2AnyChannel to an ExtId process, and connect the ExtId processes to the Merger process using One2OneChannel, your problem will be solved.

Classes
class	BarrierSyncer
	This process syncs on a barrier a specified number of times, then finishes. More...
class	BucketFlusher
	This process flushes a given bucket every time it is sent "true" on its channel, and quits when it is sent "false". More...
class	ChannelPoisoner
	Poisons the end of a channel and then exits. More...
class	EvaluateFunction
	Evaluates a function and sends out the output. More...
class	ExtId
	A process that forever performs an extended input from a channel, sending the data out on another channel as its extended action. More...
class	ExtMerger
	Merges the data from multiple channels into one, using extended input to prevent buffering. More...
class	ExtSyncId
	A process that forever performs an extended input from a channel, and for its extended action: syncs on a barrier and then sends the data out on another channel. More...
class	FunctionProcess
	This process acts like an Id process, but applies a transformation to the data before sending it on. More...
class	Id
	A process that forever forwards an item of data to another channel. More...
class	Merger
	Merges the data from multiple channels into one. More...
class	NotifySender
	A process that behaves like Id -- continually reading values and then sending them on -- but with acknowledgements when the message has been sent on. More...
class	Prefix
	A process that forwards an item of data to another channel, but starts by sending a supplied initial value. More...
class	ReaderProcess
	Reads values from a channel a specified number of times. More...
class	ReadOnceProcess
	Reads a single value from a channel into a given (by pointer) location. More...
class	SeqDelta
	A process that forever forwards an item of data to two other channels -- in sequence. More...
class	SkipProcess
	A process that does nothing. More...
class	SleepForProcess
	A process that sleeps for a specified amount of time. More...
class	SleepUntilProcess
	A process that sleeps until a specified time. More...
class	Successor
	A process that reads a value from its input channel, increments it, and writes it to the process's output channel. More...
class	WriteOnceProcess
	Writes a given value (passed by pointer) to a channel once. More...
class	WriterProcess
	Writes a given value to a channel a specified number of times. More...
