function ConstMethodCallback🔗

ConstMethodCallback() =default

function ConstMethodCallback🔗

ConstMethodCallback(
    const ConstMethodCallback & rhs
) =default

function operator=🔗

ConstMethodCallback & operator=(
    const ConstMethodCallback & rhs
) =default

function ~ConstMethodCallback🔗

~ConstMethodCallback() =default

function ConstMethodCallback🔗

template <typename ClassType >
ConstMethodCallback(
    const ClassType & objectRef,
    ConstMethodPointer< ClassType > const methodPtr
)

Constructs a ConstMethodCallback from a pointer to a specific object and a pointer to a method of that class.

Parameters:

objectRef const object reference
methodPtr pointer to a const method

function ConstMethodCallback🔗

ConstMethodCallback(
    ConstMethodCallback && rhs
)

Move constructor.

Parameters:

rhs move origin

function operator=🔗

ConstMethodCallback & operator=(
    ConstMethodCallback && rhs
)

Move assignment operator.

Parameters:

rhs move origin

Return: reference to this

function operator()🔗

template <typename... MethodArguments>
expected< ReturnValue, MethodCallbackError > operator()(
    MethodArguments &&... args
) const

Calls the method if the ConstMethodCallback is valid, otherwise it will return MethodCallbackError::UNINITIALIZED_CALLBACK.

Parameters:

args... arguments which will be perfectly forwarded to the method

Return: If ConstMethodCallback is valid the return value of the method, otherwise an error.

function operator==🔗

bool operator==(
    const ConstMethodCallback & rhs
) const

Comparison operator. Two ConstMethodCallbacks are equal if they have the same object pointer and method pointer.

function operator!=🔗

bool operator!=(
    const ConstMethodCallback & rhs
) const

Inequality operator. Two ConstMethodCallback are not equal if they have different object or method pointer.

function operator bool🔗

explicit operator bool() const

Verifies if the ConstMethodCallback is valid.

Return: true if objectRef != nullptr otherwise false

function isValid🔗

bool isValid() const

Verifies if the ConstMethodCallback is valid.

Return: true if objectRef != nullptr otherwise false

function setCallback🔗

template <typename ClassType >
void setCallback(
    const ClassType & objectRef,
    ConstMethodPointer< ClassType > methodPtr
)

Sets a new callback.

Parameters:

objectRef const reference to the object
methodPtr pointer to the method

function getObjectPointer🔗

template <typename ClassType >
const ClassType * getObjectPointer() const

Returns object pointer.

function getMethodPointer🔗

template <typename ClassType >
auto getMethodPointer() const

Returns cond method pointer.
