Member Function Documentation

◆ call_if() [1/2]

template<typename TReturn , typename... TParams>
template<typename TRet = TReturn>
ETL_CONSTEXPR14 etl::enable_if_t< etl::is_same< TRet, void >::value, bool > etl::delegate< TReturn(TParams...)>::call_if ( TParams...  args) const
inline

Execute the delegate if valid. 'void' return.

◆ call_if() [2/2]

template<typename TReturn , typename... TParams>
template<typename TRet = TReturn>
ETL_CONSTEXPR14 etl::enable_if_t<!etl::is_same< TRet, void >::value, etl::optional< TReturn > > etl::delegate< TReturn(TParams...)>::call_if ( TParams...  args) const
inline

Execute the delegate if valid. Non 'void' return.

◆ call_or() [1/2]

template<typename TReturn , typename... TParams>
template<typename TAlternative >
TReturn etl::delegate< TReturn(TParams...)>::call_or ( TAlternative  alternative,
TParams...  args 
) const
inline

Execute the delegate if valid or call alternative. Run time alternative.

◆ call_or() [2/2]

template<typename TReturn , typename... TParams>
template<TReturn(*)(TParams...) Method>
TReturn etl::delegate< TReturn(TParams...)>::call_or ( TParams...  args) const
inline

Execute the delegate if valid or call alternative. Compile time alternative.

◆ create() [1/4]

template<typename TReturn , typename... TParams>
template<typename T , TReturn(T::*)(TParams...) Method, T & Instance>
static ETL_NODISCARD ETL_CONSTEXPR14 delegate etl::delegate< TReturn(TParams...)>::create ( )
inlinestatic

Create from instance method (Compile time). New API

◆ create() [2/4]

template<typename TReturn , typename... TParams>
template<typename T , TReturn(T::*)(TParams...) const Method, T const & Instance>
static ETL_NODISCARD ETL_CONSTEXPR14 delegate etl::delegate< TReturn(TParams...)>::create ( )
inlinestatic

Create from const instance method (Compile time). New API

◆ create() [3/4]

template<typename TReturn , typename... TParams>
template<typename T , T & Instance>
static ETL_NODISCARD ETL_CONSTEXPR14 delegate etl::delegate< TReturn(TParams...)>::create ( )
inlinestatic

Create from instance function operator (Compile time). At the time of writing, GCC appears to have trouble with this.

◆ create() [4/4]

template<typename TReturn , typename... TParams>
template<typename T , TReturn(T::*)(TParams...) Method>
static ETL_NODISCARD ETL_CONSTEXPR14 delegate etl::delegate< TReturn(TParams...)>::create ( T &&  instance)
staticdelete

Create from instance method (Run time). Deleted for rvalue references.

◆ set() [1/2]

template<typename TReturn , typename... TParams>
template<typename T , TReturn(T::*)(TParams...) Method, T & Instance>
ETL_CONSTEXPR14 void etl::delegate< TReturn(TParams...)>::set ( )
inline

Set from instance method (Compile time). New API

◆ set() [2/2]

template<typename TReturn , typename... TParams>
template<typename T , TReturn(T::*)(TParams...) const Method, T const & Instance>
ETL_CONSTEXPR14 void etl::delegate< TReturn(TParams...)>::set ( )
inline

Set from const instance method (Compile time). New API
