Detailed Description

template<typename VAL_TYPE>
class SCOPED_SET_RESET< VAL_TYPE >

RAII class that sets an value at construction and resets it to the original value at destruction.

Note

There is no type deduction for template classes until C++17, \ so you can't do this:

int target = 0;
SCOPED_SET_RESET( target, 42 );

Instead, you can use a type alias, for example:

using SCOPED_INT_SET_RESET = SCOPED_SET_RESET<int>;
int target = 0;
SCOPED_INT_SET_RESET( target , 42 );
