Class RegistryServiceFuncs

java.lang.Object
  org.appdapter.osgi.registry.RegistryServiceFuncs

public class RegistryServiceFuncs
extends Object

Can work with or without OSGi. To use (possibly) outside of OSGi, use getTheWellKnownRegistry() (flexible, will try OSGi lookup first), or, to be extra something, you could call getTheWellKnownStaticRegistry(), but that will cause trouble if you really are in OSGi.

RegistryServiceFuncs()

Method Summary

static VerySimpleRegistry	getTheWellKnownRegistry() Attempts to find OSGi bundle context, using OSG Framework.getBundle(RegistryServiceFuncs.class).
static VerySimpleRegistry	getTheWellKnownRegistryUsingOptContext(org.osgi.framework.BundleContext bundleCtx) Will use the bundleCtx, if it is not null.
static VerySimpleRegistry	getTheWellKnownRegistryUsingReqContext(org.osgi.framework.BundleContext bundleCtx) Use this when you are sure you should be in OSGi, and bundleCtx should not be null.
static VerySimpleRegistry	getTheWellKnownStaticRegistry() Don't use in OSGi context, b/c you will probably wind up with two separate well known registries.
static VerySimpleRegistry	lookupTheWellKnownRegistry(org.osgi.framework.BundleContext bundleCtx) Requires OSGi context.
static <RT extends Registry> RT	lookupTheWellKnownRegistry(org.osgi.framework.BundleContext bundleCtx, Class<RT> rtClazz) Requires OSGi context.
static <RT extends Registry> org.osgi.framework.ServiceRegistration	registerTheWellKnownRegistry(org.osgi.framework.BundleContext bundleCtx, Class<RT> regClazz, RT wellKnownReg) Requires OSGi context.
static org.osgi.framework.ServiceRegistration	registerTheWellKnownRegistry(org.osgi.framework.BundleContext bundleCtx, VerySimpleRegistry wellKnownReg) Requires OSGi context.

registerTheWellKnownRegistry

public static <RT extends Registry> org.osgi.framework.ServiceRegistration registerTheWellKnownRegistry(org.osgi.framework.BundleContext bundleCtx,
                                                                                                        Class<RT> regClazz,

Type Parameters:

RT -

Parameters:

bundleCtx -

regClazz -

wellKnownReg -

Returns:

registerTheWellKnownRegistry

public static org.osgi.framework.ServiceRegistration registerTheWellKnownRegistry(org.osgi.framework.BundleContext bundleCtx,
                                                                                  VerySimpleRegistry wellKnownReg)

Requires OSGi context.

Parameters:

bundleCtx -

wellKnownReg -

Returns:

lookupTheWellKnownRegistry

public static <RT extends Registry> RT lookupTheWellKnownRegistry(org.osgi.framework.BundleContext bundleCtx,
                                                                  Class<RT> rtClazz)

Requires OSGi context.

Type Parameters:

RT -

Parameters:

bundleCtx -

rtClazz -

Returns:

lookupTheWellKnownRegistry

public static VerySimpleRegistry lookupTheWellKnownRegistry(org.osgi.framework.BundleContext bundleCtx)

Requires OSGi context.

getTheWellKnownRegistryUsingReqContext

public static VerySimpleRegistry getTheWellKnownRegistryUsingReqContext(org.osgi.framework.BundleContext bundleCtx)

Use this when you are sure you should be in OSGi, and bundleCtx should not be null.

Parameters:

bundleCtx -

Returns:

getTheWellKnownStaticRegistry

public static VerySimpleRegistry getTheWellKnownStaticRegistry()

Don't use in OSGi context, b/c you will probably wind up with two separate well known registries.

getTheWellKnownRegistryUsingOptContext

public static VerySimpleRegistry getTheWellKnownRegistryUsingOptContext(org.osgi.framework.BundleContext bundleCtx)

Will use the bundleCtx, if it is not null. Else will use static registry.

Parameters:

bundleCtx -

Returns:

getTheWellKnownRegistry

public static VerySimpleRegistry getTheWellKnownRegistry()

Attempts to find OSGi bundle context, using OSG Framework.getBundle(RegistryServiceFuncs.class). Uses it when successful, otherwise uses static version.

Returns:
