Create a dynamic accumulator chain containing the selected statistics and their dependencies.
DynamicAccumulatorChain is used to compute global statistics with run-time activation. A set of statistics is selected at run-time and from this set statistics can be activated at run-time by calling activate<stat>() or activate(std::string stat).
The template parameters are as follows:
Usage:
Usage, using CoupledHandle:
See Feature Accumulators for more information and examples of use.
| void activate | ( | std::string | tag | ) | 
Activate statistic 'tag'. Alias names are not recognized. If the statistic is not in the accumulator chain a PreconditionViolation is thrown.
| void activate | ( | ) | 
activate<TAG>() activates statistic 'TAG'. If the statistic is not in the accumulator chain it is ignored. (?)
| void activateAll | ( | ) | 
Activate all statistics in the accumulator chain.
| bool isActive | ( | std::string | tag | ) | const | 
Return true if the statistic 'tag' is active, i.e. activate(std::string tag) or activate<TAG>() has been called. If the statistic is not in the accumulator chain a PreconditionViolation is thrown. (Note that alias names are not recognized.)
| bool isActive | ( | ) | const | 
isActive<TAG>() returns true if statistic 'TAG' is active, i.e. activate(std::string tag) or activate<TAG>() has been called. If the statistic is not in the accumulator chain, true is returned. (?)
| ArrayVector<std::string> activeNames | ( | ) | const | 
Return names of all statistics in the accumulator chain that are active.
| unsigned int passesRequired | ( | ) | const | 
Return number of passes required to compute the active statistics in the accumulator chain.
