Detailed Description

template<class T>
class Dune::DebugAllocator< T >

Allocators implementation which performs different kind of memory checks.

We check:

• access past the end
• only free memory which was allocated with this allocator
• list allocated memory chunks still in use upon destruction of the allocator

When defining DEBUG_ALLOCATOR_KEEP to 1, we also check

• double free
• access after free

When defining DEBUG_NEW_DELETE >= 1, we

• overload new/delte
• use the Debug memory management for new/delete
• DEBUG_NEW_DELETE > 2 gives extensive debug output

void Dune::DebugAllocator< T >::construct ( pointer  p, _Args &&...  __args  )

inline

construct an object of type T from variadic parameters

Note

works only with newer C++ compilers
