Examples with NamespaceService org.eclipse.vorto.repository.services.NamespaceService used on opensource projects

Example 1 with NamespaceService

use of org.eclipse.vorto.repository.services.NamespaceService in project vorto by eclipse.

the class NamespaceRequestCache method namespace.

/**
 * Resolves a cached {@link Namespace} by name if applicable.<br/>
 * This will also attempt to resolve a "virtual" namespace string, consisting in the real
 * namespace appended with an arbitrary number of {@literal .[sub-namespace]} strings to the
 * root namespace.<br/>
 * The latter is useful when invoking e.g. {@link NamespaceService#getByName(String)} with
 * {@link ModelId#getNamespace()} since the latter does not trim out the "virtual" sub-namespaces.
 * <br/>
 * For instance, when given {@literal com.bosch.iot.suite.example.octopussuiteedition}:
 * <ol>
 *   <li>
 *     Attempts to resolve {@literal com.bosch.iot.suite.example.octopussuiteedition} and get
 *     its workspace ID, which fails
 *   </li>
 *   <li>
 *     Attempts to resolve {@literal com.bosch.iot.suite.example} and get its workspace ID, which
 *     fails again
 *   </li>
 *   <li>
 *     Attempts to resolve {@literal com.bosch.iot.suite} and get its workspace ID, which
 *     succeeds
 *   </li>
 * </ol>
 * Note: virtual namespaces are cached within the scope of a request. <br/>
