TBCI::tbci_memalloc_cache< T > Struct Template Reference

For specializations of the memory allocator:

Freed (dealloced) memory blocks are not actually freed, but kept in a little cache, so an allocation to a block of the same size shortly after will succeed without a call to new/malloc/memalign.

Detailed Description

template<typename T>
struct TBCI::tbci_memalloc_cache< T >

For specializations of the memory allocator:

Freed (dealloced) memory blocks are not actually freed, but kept in a little cache, so an allocation to a block of the same size shortly after will succeed without a call to new/malloc/memalign.

This happens often for TBCI and thus helps to speed up operations like assignement.
Specialization is only suitable for types that do nothing in their default c'tor, such as all elementary types.
