operator delete()

template<class T , size_t Size>

void operator delete ( void *  , roc::core::Optional< T, Size > &    ) throw ( )

inline

Placement delete for core::Optional.

Note

Compiler calls this if ctor throws in a placement new expression.

operator new()

template<class T , size_t Size>

void* operator new ( size_t  size, roc::core::Optional< T, Size > &  opt  ) throw ( )
