A given Mapper is accompanied by a Strategy by providing strategyInitializer when using createMapper().
A Strategy will be responsible for:
- Discover metadata (eg: classes uses @AutoMap() decorator to discover the metadata of the properties on the Classes)classes
- Retrieve metadata: how the metadata should be retrieved from the discovery phase (eg: discovers and stores the metadata to Reflect, retrieve metadata simply gets them from Reflect)
- Apply metadata: how the metadata is applied to the Model
