global items used by CAccountant:
member variables of CAccountant:
EBool
crashed_: the crash status of the module.
default and reset value: False
double
probCrash_: probability of crashing.
default and reset value: 0
double
probRecover_: probability of recovering.
default and reset value: 0
member functions of CAccountant:
CCrashingModule
(): Calls Reset() to set all members to their default values.
virtual
void Crash (): Sets crashed to True and calls ReportCrashChange().
EBool
Crashed () const: Returns the value of member crashed.
virtual
EBool ExecuteCommand (const SCommand& command): Returns True if
the command is supported. Supported commands:
All other commands are not supported and False is returned.
double
GetProbability (EBool probCrash) const: If probCrash is True,
the value of member probCrash is returned, else the value of member
probRecover is returned.
virtual
EBool ModifyCrashStatus (): May change the crash status of the module
(according to the current crash status and the appropriate probability
for leaving that state). The status is changed through a call to function
Crash() or Recover(), whatever is appropriate. The function
returns True if the status was changed.
virtual
void Recover (): Sets crashed to False and calls ReportCrashChange().
virtual
void ReportCrashChange(): Empty.
Derived modules should send an event with the type CrashStatusChange
to the evaluation.
void
Reset (): Sets or restores the initial state.
EBool
SetProbability (EBool probCrash, double prob): If prob is
not in [0,1], the function returns False and has no effect. Otherwise,
if probCrash is True, member probCrash is set to prob,
else member probRecover is set to prob. In any case,
the function returns True if the member was set.
