Detailed Description

template<class ValueType, class SystemTag>
class bc::allocators::Stack_Allocator< ValueType, SystemTag >

An unsynced memory pool implemented as a stack.

Deallocation must happen in reverse order of deallocation. This class is used with bc::Tensor_Base expressions to enable very fast allocations of temporaries.
