Detailed Description

Singleton class keeping configurables of analysis components.

Object of this class is created on the first call and remains in memory such, that once parameters are configured they remain the same for every call. For example: AnalysisConfigurationModule creates AnalysisConfiguration object and set configurable value by line:

AnalysisConfiguration::instance()->setTupleStyle(m_tupleStyle);

Than, NTupleTools use functions inherited from DecayDescriptor and in these get parameter value from AnalysisConfiguration object:

AnalysisConfiguration::instance()->getTupleStyle()

If object was not created before by AnalysisConfiguration module, it is created on first call with default values by NTupleTool.

By now, this class configures only style of variables in tuples and thus has two specific functions:

const string getTupleStyle() which returns chosen style void setTupleStyle(string v) which sets style

Also, it has static AnalysisConfiguration *instance() which returns pointer to previously created AnalysisClass object or, if it is the first call, create object and return pointer to it. Constructor of class is private, so the only way to create object is through instance() function.
