Detailed Description

template<class T, class SegmentManager, std::size_t NodesPerBlock, std::size_t MaxFreeBlocks, unsigned char OverheadPercent>
singleton boost::interprocess::private_adaptive_pool< T, SegmentManager, NodesPerBlock, MaxFreeBlocks, OverheadPercent >

An STL node allocator that uses a segment manager as memory source.

The internal pointer type will of the same type (raw, smart) as "typename SegmentManager::void_pointer" type. This allows placing the allocator in shared memory, memory mapped-files, etc... This allocator has its own node pool.

NodesPerBlock is the minimum number of nodes of nodes allocated at once when the allocator needs runs out of nodes. MaxFreeBlocks is the maximum number of totally free blocks that the adaptive node pool will hold. The rest of the totally free blocks will be deallocated with the segment manager.

OverheadPercent is the (approximated) maximum size overhead (1-20%) of the allocator: (memory usable for nodes / total memory allocated from the segment manager)
