Detailed Description

template<size_t requestedBlockSize = 8192, typename FixedAllocator = AllocatorFixed<AllocatorMalloc>>
class lass::util::AllocatorSimpleBlock< requestedBlockSize, FixedAllocator >

A simple fixed-size block allocator.

• concept: FixedAllocator
• thread UNSAFE.
• not copy-constructible, not assignable
• The blocks are only deallocated at destruction time to simplify the allocation/deallocation logic. However, nodes that are deallocate can still be reused.
• It is NOT SAFE to deallocate memory using another instance of AllocatorSimpleBlock than the one used to allocate it.
