Class RegistryContributor

  • All Implemented Interfaces:
    IContributor

    public final class RegistryContributor
    extends Object
    implements IContributor
    This class describes a registry contributor which is an entity that supplies information to the extension registry. Depending on the registry strategy, contributor might delegate some of its functionality to a "host" contributor. For instance, OSGi registry strategy uses "host" contributor to delegate some functionality from fragments to plug-ins.

    This class can be instantiated by the registry Service Providers.

    This class can be used without OSGi running.

    This class can not be extended.

    Since:
    org.eclipse.equinox.registry 3.2
    Restriction:
    This class is not intended to be subclassed by clients.

      • RegistryContributor

        public RegistryContributor​(String actualId,
                                   String actualName,
                                   String hostId,
                                   String hostName)
        Constructor for the registry contributor.

        The actual ID is a string identifier for the contributor (e.g., "12") and is expected to be unique within the workspace. The actual ID of the contributor must not be null.

        The actual name is the name associated with the contributor (e.g., "org.eclipse.core.runtime.fragment"). The actual name of the contributor must not be null.

        The host ID is the identifier associated with the entity "in charge" of the contributor (e.g., "1"). IDs are expected to be unique in the workspace. If contributor does not rely on a host, then null should be used as the host ID.

        The host name is the name of the entity "in charge" of the contributor (e.g., "org.eclipse.core.runtime"). If contributor does not rely on a host, then null should be used as the host name.

        There should be 1-to-1 mapping between the contributor and the contibutor ID. The IDs (either actual or host) can not be re-used in the same registry. For example, if ID of 12 was used to identify contributorA, the ID of 12 can not be used to identify contributorB or a host for the contributorC.

        Parameters:
        actualId - contributor identifier
        actualName - name of the contributor
        hostId - id associated with the host, or null
        hostName - name of the host, or null
