Check for cyclic dependencies.
@ c_setDecayInfo
Set decay time and vertex.
void setDescription(const std::string &description)
Sets the description of the module.
void setPropertyFlags(unsigned int propertyFlags)
Sets the flags for the module properties.
@ c_Input
This module is an input module (reads data).

Register the object/array in the DataStore.
Accessor to arrays stored in the data store.
void addParam(const std::string &name, T ¶mVariable, const std::string &description, const T &defaultValue)
Adds a new parameter to the module.
#define REG_MODULE(moduleName)
Register the given module (without 'Module' suffix) with the framework.
Abstract base class for different kinds of events.
