[in]	methodPtr	pointer to a method

MethodCallback() [2/2]

template<typename ReturnValue , typename... Args>

iox::cxx::MethodCallback< ReturnValue, Args >::MethodCallback ( MethodCallback< ReturnValue, Args > &&  rhs )

noexcept

Parameters

[in]

rhs

move origin

Member Function Documentation

isValid()

template<typename ReturnValue , typename... Args>

bool iox::cxx::MethodCallback< ReturnValue, Args >::isValid ( ) const

noexcept

Verifies if the MethodCallback is valid.

Returns

true if objectRef != nullptr otherwise false

operator bool()

template<typename ReturnValue , typename... Args>

iox::cxx::MethodCallback< ReturnValue, Args >::operator bool ( ) const

explicitnoexcept

Verifies if the MethodCallback is valid.

Returns

true if objectRef != nullptr otherwise false

operator()()

template<typename ReturnValue , typename... Args>

template<typename... MethodArguments>

expected< ReturnValue, MethodCallbackError > iox::cxx::MethodCallback< ReturnValue, Args >::operator() ( MethodArguments &&...  args )

noexcept

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

Parameters

[in]

args...

arguments which will be perfectly forwarded to the method

Returns

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

operator=()

template<typename ReturnValue , typename... Args>

MethodCallback & iox::cxx::MethodCallback< ReturnValue, Args >::operator= ( MethodCallback< ReturnValue, Args > &&  rhs )

noexcept

Move assignment operator.

Parameters

[in]

rhs

move origin

Returns

reference to this

setCallback()

template<typename ReturnValue , typename... Args>

template<typename ClassType >

void iox::cxx::MethodCallback< ReturnValue, Args >::setCallback ( ClassType &  objectRef, MethodPointer< ClassType >  methodPtr  )

noexcept

Sets a new callback.

Parameters

[in]	objectRef	const reference to the object
[in]	methodPtr	pointer to the method
