Detailed Description

Workspace encapsulation class.

Base class for objects that allocate a huge block of memory at once and then allow RawWorkspace (an hense Workspace<T>) objects to be created that make use of this memory in a stack-like fasion. The classes WorkspaceStore and RawWorkspace work closely together and are useless on their own.

Through this interface, a client can not initialize or resize the size of the available workspace and can not directly instantiate objects of this type. Instead it must create a derived WorkspaceStoreInitializeable object defined later.
