Take ownership of the algorithms subtructure (sub-algorithms,...) by copying them from the AlgFactory pool to the local pool Also bring all the configuration variables to the top level config Registry. This can be used to group together a series of algorithms & their configurations and extract (a clone of) this group from the shared pools. Having a series of algorithms/configurations behaving as a monolithic block, with a single point of configuration (the top level) is to be used when bits & pieces of GENIE are used in isolation for data fitting or reweighting

void DMELKinematicsGenerator::Configure ( string  config)
virtual

Configure the algorithm from the AlgoConfigPool based on param_set string given in input An algorithm contains a vector of registries coming from different xml configuration files, which are loaded according a very precise prioriy This methods will load a number registries in order of priority: 1) "Tunable" parameter set from CommonParametes. This is loaded with the highest prioriry and it is designed to be used for tuning procedure Usage not expected from the user. 2) For every string defined in "CommonParame" the corresponding parameter set will be loaded from CommonParameter.xml 3) parameter set specified by the config string and defined in the xml file of the algorithm 4) if config is not "Default" also the Default parameter set from the same xml file will be loaded Effectively this avoids the repetion of a parameter when it is not changed in the requested configuration

Get configuration registry Evaluate the summary of the configuration and returns it The summary of a configuration is a merge of all the registries known to the algorithm (see Configure() methods) but every parameter is appearing only once and in case of repetitions, only the parameter from the registry with the highest prioriry is considered.
