Public Functions Documentation🔗

function MethodCallback🔗

MethodCallback() =default

function MethodCallback🔗

MethodCallback(
    const MethodCallback & rhs
) =default

function operator=🔗

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

function ~MethodCallback🔗

~MethodCallback() =default

function MethodCallback🔗

template <typename ClassType >
MethodCallback(
    ClassType & objectRef,
    MethodPointer< ClassType > methodPtr
)

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

Parameters:

objectRef object reference
methodPtr pointer to a method

function MethodCallback🔗

MethodCallback(
    MethodCallback && rhs
)

Move constructor.

Parameters:

rhs move origin

function operator=🔗

MethodCallback & operator=(
    MethodCallback && rhs
)

Move assignment operator.

Parameters:

rhs move origin

Return: reference to this

function operator()🔗

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

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

Parameters:

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

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

function operator==🔗

bool operator==(
    const MethodCallback & rhs
) const

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

function operator!=🔗

bool operator!=(
    const MethodCallback & rhs
) const

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

function operator bool🔗

explicit operator bool() const

Verifies if the MethodCallback is valid.

Return: true if objectRef != nullptr otherwise false

function isValid🔗

bool isValid() const

Verifies if the MethodCallback is valid.

Return: true if objectRef != nullptr otherwise false

function setCallback🔗

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

Sets a new callback.

Parameters:

objectRef const reference to the object
methodPtr pointer to the method

function getObjectPointer🔗

template <typename ClassType >
ClassType * getObjectPointer() const

Returns objectRef.

function getMethodPointer🔗

template <typename ClassType >
auto getMethodPointer() const

Returns cond method pointer.
