public interface ComponentOverride

Service that allows replacing one component, page or mixin class by another without changing the sources. This service shouldn't be used directly: it's not an internal service just because it receives contributions. Contributions to it are mapped: the key is the component, page or mixin class to be replaced, the value is the replacement.
