public final class DataScanResult extends MetadataScanResult
Represents the result of a container data scan. A container data scan will do a full metadata check, and check the contents of all block data within the container. The result will contain all the errors seen while scanning the container, and a ContainerMerkleTree representing the data that the scan saw on the disk when it ran.
