PEL_PropQueue  [constructor]

PEL_PropQueue(void);

Constructs a propagation queue.

enqueue  [member function]

void enqueue(int fnct_idx);

Enqueue a propagation function index fnct_idx. The propagation function index is related to a propagation function table.

dequeue  [member function]

int dequeue(void);

Returns a propagation function index.

apply  [member function]

pf_return_t apply(PEL_PropFnctTable &pft,  
                  PEL_ParamTable &pt,  
                  PEL_SuspVar * []);

Dequeues an index and applies the corresponding propagation function closure of pft. It returns the value returned by the propagation function.

isEmpty  [member function]

setFailed  [member function]

void setFailed(void);

Sets the queue failed.

isFailed  [member function]

isBasic  [member function]

int isBasic(void);

Tests if all propagation functions registered with the queue have ceased to exist.

incAPF  [member function]

void incAPF(void);

Increments the registration counter by 1.

decAPF  [member function]

void decAPF(void);

Decrements the registration counter by 1.

reset  [member function]

void reset(void);

Resets the queue. (???)

getSize  [member function]

int getSize(void);
