Bundle Capability and Requirement Namespace.

This class defines the names for the attributes and directives for this namespace. All unspecified capability attributes are of type String and are used as arbitrary matching attributes for the capability. The values associated with the specified directive and attribute keys are of type String, unless otherwise indicated.

Unless otherwise noted, all directives specified on the Bundle-SymbolicName header are visible in the capability and all directives specified on the Require-Bundle header are visible in the requirement.

  • The uses directive must be ignored. A uses directive specified on the Bundle-SymbolicName header must be ignored. A uses directive must not be present in the capability.
  • The effective directives must be ignored. This namespace is only effective at resolve time. An effective directive specified on the Bundle-SymbolicName or Require-Bundle headers must be ignored. An effective directive must not be present in a capability or requirement.
  • The cardinality directive must be ignored. A cardinality directive specified on the Require-Bundle header must be ignored. A cardinality directive must not be present in a requirement.

A non-fragment resource with the osgi.bundle type identity provides exactly one bundle capability (that is, the bundle can be required by another bundle). A fragment resource with the osgi.fragment type identity must not declare a bundle capability. A resource requires zero or more bundle requirements (that is, required bundles).

† A resource with no symbolic name must not provide a bundle capability.

 public final class BundleNamespace extends AbstractWiringNamespace {

Namespace name for bundle capabilities and requirements.

Also, the capability attribute used to specify the symbolic name of the bundle.

 
 	public static final String	BUNDLE_NAMESPACE"osgi.wiring.bundle";

The capability directive identifying if the resource is a singleton. A String value of "true" indicates the resource is a singleton; any other value or null indicates the resource is not a singleton.

This directive should be examined using the identity namespace.

 
 	public static final String	CAPABILITY_SINGLETON_DIRECTIVE"singleton";

The capability directive identifying if and when a fragment may attach to a host bundle.

This directive should be examined using the host namespace.

	public static final String	CAPABILITY_FRAGMENT_ATTACHMENT_DIRECTIVE"fragment-attachment";

The requirement directive used to specify the type of the extension fragment.

This directive should be examined using the host namespace.

	public final static String	REQUIREMENT_EXTENSION_DIRECTIVE"extension";

The requirement directive used to specify the visibility type for a requirement. The default value is private.

See also:
VISIBILITY_PRIVATE private
VISIBILITY_REEXPORT reexport
	public final static String	REQUIREMENT_VISIBILITY_DIRECTIVE"visibility";

The directive value identifying a private visibility type. A private visibility type indicates that any packages that are exported by the required bundle are not made visible on the export signature of the requiring bundle. .

	public final static String	VISIBILITY_PRIVATE"private";

The directive value identifying a reexport visibility type. A reexport visibility type indicates any packages that are exported by the required bundle are re-exported by the requiring bundle.

	public final static String	VISIBILITY_REEXPORT"reexport";
	private BundleNamespace() {
		// empty
	}
