Detailed Description

Active object class (based on QMsm implementation strategy)

Description
QMActive represents an active object that uses the QMsm style state machine implementation strategy. This strategy requires the use of the QM modeling tool to generate state machine code automatically, but the code is faster than in the QHsm style implementation strategy and needs less run-time support (smaller event-processor).
Note
QMActive is not intended to be instantiated directly, but rather serves as the base class for derivation of active objects in the application.
Traceability
Usage
The following example illustrates how to derive an active object from QMActive. Please note that the QActive member super is defined as the first member of the derived struct (see Object Orientation). Please also note the call to the QMActive_ctor() in the Blinky subclass' constructor.
typedef struct {
QMActive super; // <=== inherit QMActive
QTimeEvt timeEvt; // to timeout the blinking
} Blinky;
. . .
void Blinky_ctor(Blinky * const me) {
// constructor of the superclass <===
QMActive_ctor(&me->super, Q_STATE_CAST(&Blinky_initial));
// constructor(s) of the members
QTimeEvt_ctorX(&me->timeEvt, &me->super, TIMEOUT_SIG, 0U);
}

◆ QMActive_ctor()

void QMActive_ctor ( QMActive *const me,
QStateHandler const initial )
protected

Constructor of QMActive class.

Description
Performs the first step of active object initialization by assigning the virtual pointer and calling the superclass constructor.
Parameters
[in,out]mecurrent instance pointer (see Object Orientation)
[in]initialpointer to the event to be dispatched to the MSM
Note
Must be called only ONCE before QASM_INIT().
