Envir and Extensions

Description

Simulations take input in the form of parameters and configuration settings, and produce various outputs such as statistical results, log, etc. Implementations of such input and output facilities are not part of the simulation core (cSimulation,etc.), but instead, they are delegated to the "environment" of the simulation, represented by the cEnvir interface. The Envir library (src/envir) contains the default implementation of cEnvir.

cEnvir is a facade which delegates most of its subtasks to further components: cConfiguration, cIOutputScalarManager etc, which themselves may have multiple alternative implementations.

• cEnvir represents the "environment" of the simulation
• cConfiguration provides parameter values and configuration settings
• cIOutputScalarManager is an interface for recording scalar results (.sca files)
• cIOutputVectorManager is an interface for recording vector results (.vec files)
• See list for more interfaces
