Helidon Config Mapping Example

This example shows how to implement mappers that convert configuration to POJOs.

1. BuilderExample.java shows how you can add a builder() method to a POJO. That method returns a Builder object which the config system uses to update with various key settings and then, finally, invoke build() so the builder can instantiate the POJO with the assigned values.
2. DeserializationExample.java uses the config system's support for automatic mapping to POJOs that have bean-style setter methods.
3. FactoryMethodExample.java illustrates how you can add a static factory method create to a POJO to tell the config system how to construct a POJO instance.
