Detailed Description

template<typename T, typename Deleter>
class SlHelpers::PtrStore< T, Deleter >

A store for a pointer which is freed in the destructor using sqlite3_free()

Member Function Documentation

◆ ptr()

template<typename T , typename Deleter >
T** SlHelpers::PtrStore< T, Deleter >::ptr ( )
inlinenoexcept

Get a pointer to the internal pointer.

Returns
Pointer to the internal pointer.

Usually to assign to the pointer. The previous pointer is freed if it was valid.

◆ str()

template<typename T , typename Deleter >
std::string_view SlHelpers::PtrStore< T, Deleter >::str ( ) const
inlinenoexcept

Return the current pointer as string.

Returns
The current pointer as a string or empty string if the pointer is not valid.
