Detailed Description

template<class T>
struct dg::Buffer< T >

a manager class that invokes the copy constructor on the managed ptr when copied (deep copy)

this class is most useful as a memory buffer for classes that need some workspace to fulfill their task but do otherwise not change their state. A buffer object can be declared const while the data it holds are still writeable.

Template Parameters

T	must be default constructible and copyable
