List of all members.

## Public Member Functions
| RV (ivec in_ids, Array< std::string > in_names, ivec in_sizes, ivec in_times)
| Full constructor which is called by the others.
| RV (ivec ids)
| default constructor
| RV ()
| Empty constructor will be set later.
int | count () const
| Return number of scalars in the RV.
int | length () const
| Return length (number of entries) of the RV.
ivec | find (RV rv2)
| Find indexes of another rv in self.
bool | equal (RV rv2) const
| Compare if `rv2` is identical to this `RV`.
void | add (const RV &rv2)
| Add (concat) another variable to the current one.
RV | subt (RV rv2)
| Subtract another variable from the current one.
RV | subselect (ivec ind)
| Select only variables at indeces ind.
RV | operator() (ivec ind)
| Select only variables at indeces ind.
void | t (int delta)
| Generate new `RV` with `time` shifted by delta.
ivec | indexlist ()
| generate a list of indeces, i.e. which
Array< std::string > & | _names ()
| access function
int | id (int at)
| access function
int | size (int at)
| access function
int | time (int at)
| access function
std::string | name (int at)
| access function
## Protected Attributes
int | tsize
| size = sum of sizes
int | len
| len = number of individual rvs
ivec | ids
| Vector of unique IDs.
ivec | sizes
| Vector of sizes.
ivec | times
| Vector of shifts from current time.
Array< std::string > | names
| Array of names.
## Friends
std::ostream & | operator<< (std::ostream &os, const RV &rv)
| Printing output e.g. for debugging.
RV | concat (const RV &rv1, const RV &rv2)
| Add (concat) another variable to the current one.
