org.osgi.core 6.0.0 · org.osgi.framework.namespace.HostNamespace

Host 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 Fragment-Host 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 Fragment-Host headers must be ignored. An effective directive must not be present in a capability or requirement.
The cardinality directive has limited applicability to this namespace. A cardinality directive specified on the Fragment-Host header must be ignored. All requirements must have the cardinality directive set to multiple.

A non-fragment resource with the with the osgi.bundle type identity provides zero or one^† host capabilities. A fragment resource with the osgi.fragment type identity must not declare a host capability and must declare exactly one host requirement.

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

CAPABILITY_FRAGMENT_ATTACHMENT_DIRECTIVE back to summary

CAPABILITY_FRAGMENT_ATTACHMENT_DIRECTIVE	back to summary
public static final String CAPABILITY_FRAGMENT_ATTACHMENT_DIRECTIVE The capability directive identifying if and when a fragment may attach to a host bundle. The default value is `always`. See Also `FRAGMENT_ATTACHMENT_ALWAYS`, `FRAGMENT_ATTACHMENT_RESOLVETIME`, `FRAGMENT_ATTACHMENT_NEVER`

public static final String CAPABILITY_FRAGMENT_ATTACHMENT_DIRECTIVE

CAPABILITY_SINGLETON_DIRECTIVE back to summary

CAPABILITY_SINGLETON_DIRECTIVE	back to summary
public static final 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`

public static final 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.
