Class BundleNamespace
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
usesdirective must be ignored. Ausesdirective specified on theBundle-SymbolicNameheader must be ignored. Ausesdirective must not be present in the capability. - The
effectivedirectivesmust be ignored. This namespace is only effective atresolvetime. Aneffectivedirective specified on theBundle-SymbolicNameorRequire-Bundleheaders must be ignored. Aneffectivedirective must not be present in a capability or requirement. - The
cardinalitydirective must be ignored. Acardinalitydirective specified on theRequire-Bundleheader must be ignored. Acardinalitydirective 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.

Field Details

BUNDLE_NAMESPACE
Namespace name for bundle capabilities and requirements.Also, the capability attribute used to specify the symbolic name of the bundle.
- See Also:
-
CAPABILITY_SINGLETON_DIRECTIVE
The capability directive identifying if the resource is a singleton. AStringvalue of "true" indicates the resource is a singleton; any other value ornullindicates the resource is not a singleton.This directive should be examined using the
identitynamespace.- See Also:
-
CAPABILITY_FRAGMENT_ATTACHMENT_DIRECTIVE
The capability directive identifying if and when a fragment may attach to a host bundle.This directive should be examined using the
hostnamespace.- See Also:
-
REQUIREMENT_EXTENSION_DIRECTIVE
The requirement directive used to specify the type of the extension fragment.This directive should be examined using the
hostnamespace.- See Also:
-
REQUIREMENT_VISIBILITY_DIRECTIVE
The requirement directive used to specify the visibility type for a requirement. The default value isprivate.- See Also:
-
VISIBILITY_PRIVATE
The directive value identifying a privatevisibilitytype. A private visibility type indicates that anypackagesthat are exported by the required bundle are not made visible on the export signature of the requiring bundle. .- See Also:
-
VISIBILITY_REEXPORT
The directive value identifying a reexportvisibilitytype. A reexport visibility type indicates anypackagesthat are exported by the required bundle are re-exported by the requiring bundle.- See Also:
