Class ManifestChainResolver

java.lang.Object

com.tccc.kos.core.util.DirectoryKabSource

com.tccc.kos.core.primary.service.nodemgr.install.ManifestChainResolver

All Implemented Interfaces:

KabSource

public class ManifestChainResolver
extends DirectoryKabSource

Given a directory containing manifest kabs, organize the manifests into chains that are compatible with the specified device type and are complete. This solves the problem of identifying the head of a manifest chain without requiring any additional hints. This is typically used on conjunction with USB update where a drive may just contain a collection of kabs.

As this is also a KabSource, this can also be used to construct a DeviceInstallBuidler, allowing both chain resolution and installation to occur using the resolver.
