Annotation Interface ProvideCapability

@Deprecated @Retention(CLASS) @Target({ANNOTATION_TYPE,TYPE}) public @interface ProvideCapability
Deprecated.
see org.osgi.annotation.bundle.Capability
Define a Provide Capability clause in the manifest.

Since this annotation can only be applied once, it is possible to create an annotation that models a specific capability. For example: 

 interface Webserver {
        @ProvideCapability(ns = "osgi.extender", name = "aQute.webserver", version = "${@version}")
        @interface Provide {}

        @RequireCapability(ns = "osgi.extender", filter = "(&(osgi.extender=aQute.webserver)${frange;${@version}})")
        @interface Require {}
 }

 @Webserver.Provide
 public class MyWebserver {}

  • Element Details

    • ns

      String ns
      Deprecated.
      The capability namespace. For example: osgi.contract.

    • value

      String value
      Deprecated.
      Appended at the end of the clause (after a ';'). Can be used to add additional attributes and directives.
      Default:
      ""

    • name

      String name
      Deprecated.
      The name of the capability. If this is set, a property will be added as {ns}={name}. This is the custom pattern for OSGi namespaces. Leaving this unfilled, requires the value() to be used to specify the name of the capability, if needed. For example aQute.sse.
      Default:
      ""

    • version

      String version
      Deprecated.
      The version of the capability. This must be a valid OSGi version.
      Default:
      ""

    • effective

      String effective
      Deprecated.
      Effective time. Specifies the time a capability is available, either resolve (default) or another name. The OSGi framework resolver only considers Capabilities without an effective directive or effective:=resolve. Capabilities with other values for the effective directive can be considered by an external agent.
      Default:
      "resolve"

    • uses

      String[] uses
      Deprecated.
      The uses directive lists package names that are used by this Capability. This information is intended to be used for uses constraints,
      Default:
      {}

    • mandatory

      String[] mandatory
      Deprecated.
      Mandatory attributes. Forces the resolver to only satisfy filters that refer to all listed attributes.
      Default:
      {}
