Examples of LoadedPackageBitsComposite

org.rhq.core.domain.content.composite.LoadedPackageBitsComposite
Composite object built by a query that indicates if a package version's contents (its "bits") is loaded/available and (if loaded) if the contents are stored in the database. @author John Mazzitelli @see PackageBits#QUERY_PACKAGE_BITS_LOADED_STATUS_PACKAGE_VERSION_ID
