Interface MpConfigFilter

All Known Implementing Classes:
MpEncryptionFilter
public interface MpConfigFilter
Filtering support for MicroProfile config implementation. The current specification does not have a way to intercept values as they are delivered. As we want to support filtering capabilities (such as for configuration encryption), this is a temporary solution (or permanent if the MP spec does not add any similar feature).
