CNKProc* getProc(int i);

CNKProc* getProc(const char* name);

int getNumBufs();

CNKBuf* getBuf(int i);

These are methods for adding and removing CNKProc and CNKBuf

objects from a pipeline. At any point, a pipeline contains an ordered

list of

CNKProc objects and an ordered list of CNKBuf objects. The

addProc, removeProc, addBuf, and removeBuf methods add or remove

a given

CNKProc or CNKBuf from the corresponding list. The

getNumProcs() and getNumBufs() methods return the sizes of the two

lists. The

getProc and getBuf methods allow retrieving a CNKProc or

CNKBuf by index in the list (0..N-1), or by the name of the CNKProc or

CNKBuf (according to CNKObj::getName()).

CNKPipeline::

void execute(long max_exec);

int getAnyProcReady();

The CNKPipeline::execute method executes the pipeline by

repeatedly calling the

execute() method of CNKProc objects in the

pipeline. Before calling the

CNKProc::execute method for a CNKProc,

the

CNKProc's isReady and isDone methods are called to check

whether it is ready to execute. If none of the

CNKProc objects are

ready to execute, then this method returns: the pipeline is done.

If the

max_exec argument is 0 or less, then the pipeline is executed

until none of the

CNKProc objects are ready to execute. If max_exec is

greater than

0, then the CNKPipeline::execute method will return

after calling

CNKProc::execute at most max_exec times.

Every time that the

CNKPipeline::execute method calls the

execute() method for a CNKProc, it also calls

CNKProc::incrementExecuteCount(), to update the count of the times

that the

CNKProc has been executed.

The

getAnyProcReady() method returns true (non-zero) if at least one

of the

CNKProc objects in the pipeline is ready to execute.
