Public Member Functions

 RawWorkspace (WorkspaceStore *workspace_store, size_t num_bytes)
 Allocate num_bytes bytes of temporary workspace. When this object is created if workspace_store != NULL the workspace_store object will be used to get the raw memory. If workspace_store == NULL || workspace_store->num_bytes_remaining() < num_bytes then this memory will have to be dynamically allocated.
 ~RawWorkspace ()
 Deallocate workspace.
size_t num_bytes () const
 Return the number of bytes of raw workspace.
char * workspace_ptr ()
 Give a raw pointer to the beginning of the workspace.
