| Stats::Formula::Formula | ( | Temp | r | ) |

| r | The root of the expression tree. |

References Stats::Temp::getNodePtr(), root, Stats::InfoAccess::setInit(), and size().
Add the given tree to the existing one.
| r | The root of the expression tree. |
Definition at line 401 of file statistics.cc.
References Stats::Temp::getNodePtr(), root, Stats::InfoAccess::setInit(), and size().
Divide the existing tree by the given one.
| r | The root of the expression tree. |
Definition at line 415 of file statistics.cc.
Set an unitialized Formula to the given root.

| void Stats::Formula::reset | ( | ) |
Formulas don't need to be reset.
Definition at line 447 of file statistics.cc.
| void Stats::Formula::result | ( | VResult & | vec | ) | const |
Return the result of the Fomula in a vector.
If there were no Vector components to the Formula, then the vector is size 1. If there were, like x/y with x being a vector of size 3, then the result returned will be x[0]/y, x[1]/y, x[2]/y, respectively.

| size_type Stats::Formula::size | ( | ) | const |
Return the number of elements in the tree.

| Result Stats::Formula::total | ( | ) | const |
Return the total Formula result.
If there is a Vector component to this Formula, then this is the result of the Formula if the formula is applied after summing all the components of the Vector. For example, if Formula is x/y where x is size 3, then total() will return (x[1]+x[2]+x[3])/y. If there is no Vector component, total() returns the same value as the first entry in the VResult val() returns.
