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.

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 Detail

BUNDLE_NAMESPACE

public static final java.lang.String BUNDLE_NAMESPACE
Namespace name for bundle capabilities and requirements.

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

Constant Field Values

CAPABILITY_SINGLETON_DIRECTIVE

public static final java.lang.String CAPABILITY_SINGLETON_DIRECTIVE
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.

See Also:
IdentityNamespace.CAPABILITY_SINGLETON_DIRECTIVE, Constant Field Values

CAPABILITY_FRAGMENT_ATTACHMENT_DIRECTIVE

public static final java.lang.String 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 host namespace.

See Also:
HostNamespace.CAPABILITY_FRAGMENT_ATTACHMENT_DIRECTIVE, Constant Field Values

REQUIREMENT_EXTENSION_DIRECTIVE

public static final java.lang.String REQUIREMENT_EXTENSION_DIRECTIVE
The requirement directive used to specify the type of the extension fragment.

This directive should be examined using the host namespace.

See Also:
HostNamespace.REQUIREMENT_EXTENSION_DIRECTIVE, Constant Field Values

REQUIREMENT_VISIBILITY_DIRECTIVE

public static final java.lang.String REQUIREMENT_VISIBILITY_DIRECTIVE
The requirement directive used to specify the visibility type for a requirement. The default value is private.

See Also:
private, reexport, Constant Field Values

VISIBILITY_PRIVATE

public static final java.lang.String VISIBILITY_PRIVATE
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. .

See Also:
REQUIREMENT_VISIBILITY_DIRECTIVE, Constant Field Values

VISIBILITY_REEXPORT

public static final java.lang.String VISIBILITY_REEXPORT
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.

See Also:
REQUIREMENT_VISIBILITY_DIRECTIVE, Constant Field Values
