Class ConfigCompatibility

java.lang.Object
io.quarkus.deployment.configuration.ConfigCompatibility
public final class ConfigCompatibility extends Object
A class which manages configuration compatibility for the build-time configuration. The mechanism is to keep a matching table of old names and new names. Old names are detected at the front end iterator and mapped to the corresponding new name(s) that replace them. New names are detected at the back end getter, which queries the corresponding old name(s) to determine the new value.

This is intended to be a temporary and evolutionary solution to be replaced by generative remapping. It is more flexible than fallback remapping, allowing 1:N and N:1 remappings and support for submaps. Unfortunately it is also very verbose.
