Core principles

Goal of this infrastructure is to support the providing of specific strategies achieved by using generics. This infrastructure introduces a generic strategy interface managed by the generic strategy provider. The library introduces an IGenericStrategy<T> which needs to be implemented for every case a strategy with a given criterion is supporting. The instances of the IGenericStrategy<T> are managed by the IGenericStrategyProvider<out TStrategy, in TCriterion> which resolves the correct implementation for the given criterion. The generic parameter acts as selection criterion and declares the responsibility of the specific strategy.

Advantages

  • The generic strategy interface leads to more structured code.
  • Based on their generic type parameter, strategies are categorized and make their responsibility explicit. As a consequence this leads to higher chance of reuse and better readable code.
  • The implementation is driven by SOLID principles like open/closed, single responsibility and dependency inversion. For further explanations see Fundamentals of strategy pattern.

Implementation details

  • Introduces a generic strategy interface
  • The generic parameter represents the criterion for the selection of the specific strategy
  • Works with any IoC framework
  • For most benefit make generic type unbound IoC registration for GenericStrategyProvider<,>
