Member Function Documentation

QAsm_ctor()

void QAsm_ctor ( QAsm *const me )

protected

Constructor of the QAsm base class.

Details

The constructor initializes the QAsm::vptr and clears the internal attributes. The constructor is "protected" because it is only intended to be invoked from the subclasses of the abstract base class QAsm.

Parameters

[in,out]

me

current instance pointer (see Object Orientation)

Backward Traceability

• QAsm : Abstract State Machine class (state machine interface)

QHsm_top()

QState QHsm_top ( QHsm const *const me, QEvt const *const e )

protected

Definition at line 713 of file qep_hsm.c.

Member Data Documentation

vptr

struct QAsmVtable const* vptr

protected

Virtual pointer inherited by all QAsm subclasses (see also Object Orientation)

Backward Traceability

• QAsm : Abstract State Machine class (state machine interface)

Definition at line 260 of file qp.h.

state

union QAsmAttr state

protected

Current state (pointer to the current state-handler function)

Definition at line 265 of file qp.h.

temp

union QAsmAttr temp

protected

Temporary storage for target/act-table etc.

Backward Traceability

• QAsm : Abstract State Machine class (state machine interface)

Details

The temp data member is used for passing information from the QP Application to the "event processor" of QP. The temp member is also used as the Duplicate Inverse Storage of the state attribute in between transitions (part of QP Functional Safety (FuSa) Subsystem).
