Class MetadataConstants

java.lang.Object

io.helidon.metadata.MetadataConstants

public final class MetadataConstants
extends Object

Constants used during metadata discovery.

For backward compatibility, we must explicitly list the files that should be loaded, as we expected their location directly under LOCATION, without a directory structure and a manifest file.
