Detailed Description

template<class __ValueType, class __ReferenceType = __ValueType>
class mbo::allocator< __ValueType, __ReferenceType >

Allocator base using uninitalized memory.

Internally the handled element spaces are treated as char arrays.

Note:

No default constructors are executed.

Definition at line 94 of file reallocator.h.
