~CallBackSpy()

virtual glo::CallBackSpy::~CallBackSpy ( )

protectedvirtual

The destructor is not available. An DebugClassSpy object may only be removed from memory with CallBackSpy::destroy().

CallBackSpy() [2/2]

Member Function Documentation

create()

static void glo::CallBackSpy::create ( CallBackSpy *& prInstance )

static

Instantiation function. Since CallBackSpy is a singleton class, this method instantiates it once and then only returns the pointer to the instance.

Parameters

[in,out]

prInstance

The only instance of this class.

Attention

The delivered instance must be removed from memory with CallBackSpy::destroy().

destroy()

static int glo::CallBackSpy::destroy ( )

static

If the calling instance is the last one with a reference to the only instance of CallBackSpy, this instance is removed from memory.

Returns

Return is the number of still-references to this instance.

getCallBack() [1/2]

CallBack * glo::CallBackSpy::getCallBack

(

EnSeekMode

eMode

)

Returns a CallBack object from the list of CallBack objects related to eMode

Parameters

[in]

eMode

The seek mode.

Parameter examples:

• glo::START = returns first element
• glo::NEXT = returns next element
• glo::CURRENT = returns current element
• glo::END = no effect
• glo::PREVIOUS = no effect

Returns

If found, the CallBack object, otherwise nullptr.

Attention

The calling instance must not remove the supplied object from memory.

getCallBack() [2/2]

CallBack * glo::CallBackSpy::getCallBack

(

NUM_PTR

ipAddress

)

Returns a pointer to a CallBack object from the list of CallBack objects, which has the passed address in memory.

Parameters

[in]

ipAddress

The memory address.

Returns

The pointer to the CallBack object if found; otherwise nullptr.

Attention

The calling instance must not remove the supplied object from memory.

insertCallBack()

int glo::CallBackSpy::insertCallBack ( const CallBack * pCallBack )

protected

Inserts a CallBack object into the list of CallBack objects.

Parameters

[in]

pCallBack

The CallBack object to be inserted.

Returns

A return < 0 indicates an error.

operator=()

CallBackSpy & glo::CallBackSpy::operator= ( const CallBackSpy & )

private

m_List

std::unordered_map< NUM_PTR, CallBack * > glo::CallBackSpy::m_List

private

The list of CallBack objects. The index is the address, cast to NUM_PTR, of the individual objects.

m_ListIterator

std::unordered_map<NUM_PTR,CallBack*>::iterator glo::CallBackSpy::m_ListIterator

private

An internal iterator to the CallBack object list.

ms_iReferenceCounter

int glo::CallBackSpy::ms_iReferenceCounter

staticprotected

The reference counter to the only instance of this class.

ms_pInstance
