Method Details

initialize

protected void initialize()

createServiceBinding

protected <R extends Service> void createServiceBinding(ServiceInitiator<R> initiator)

createServiceBinding

protected <R extends Service> void createServiceBinding(ProvidedService<R> providedService)

visitServiceBindings

protected void visitServiceBindings(Consumer<ServiceBinding<?>> action)

getParentServiceRegistry

public @Nullable ServiceRegistry getParentServiceRegistry()

Description copied from interface: ServiceRegistry

Retrieve this registry's parent registry.

Specified by:

getParentServiceRegistry in interface ServiceRegistry

Returns:

The parent registry. May be null.

locateServiceBinding

public <R extends Service>
@Nullable ServiceBinding<R> locateServiceBinding(Class<R> serviceRole)

Description copied from interface: ServiceRegistryImplementor

Locate the binding for the given role. Should, generally speaking, look into parent registry if one.

Specified by:

locateServiceBinding in interface ServiceRegistryImplementor

Type Parameters:

R - generic return type.

Parameters:

serviceRole - The service role for which to locate a binding.

Returns:

The located binding; may be null

locateServiceBinding

protected <R extends Service>
@Nullable ServiceBinding<R> locateServiceBinding(Class<R> serviceRole,
 boolean checkParent)

getService

public <R extends Service> @Nullable R getService(Class<R> serviceRole)

Description copied from interface: ServiceRegistry

Retrieve a service by role, returning null if there is no such service. If service is not found, but a ServiceInitiator is registered for this service role, the service will be initialized and returned. Most of the time, use of ServiceRegistry.requireService(Class) is preferred, being much less likely to cause a NullPointerException in the client.

Specified by:

getService in interface ServiceRegistry

Type Parameters:

R - The service role type

Parameters:

serviceRole - The service role

Returns:

The requested service or null if the service was not found.

registerService

protected <R extends Service> void registerService(ServiceBinding<R> serviceBinding,
 R service)

createService

protected <R extends Service> @Nullable R createService(ServiceBinding<R> serviceBinding)

injectDependencies

public <R extends Service> void injectDependencies(ServiceBinding<R> serviceBinding)

Specified by:

injectDependencies in interface ServiceBinding.ServiceLifecycleOwner

startService

public <R extends Service> void startService(ServiceBinding<R> serviceBinding)

Specified by:

startService in interface ServiceBinding.ServiceLifecycleOwner

isActive

public boolean isActive()

destroy

public void destroy()

Description copied from interface: ServiceRegistryImplementor

Release resources

Specified by:

destroy in interface ServiceRegistryImplementor

stopService

public <R extends Service> void stopService(ServiceBinding<R> binding)

Specified by:

stopService in interface ServiceBinding.ServiceLifecycleOwner

registerChild

public void registerChild(ServiceRegistryImplementor child)

Description copied from interface: ServiceRegistryImplementor

When a registry is created with a parent, the parent is notified of the child via this callback.

Specified by:

registerChild in interface ServiceRegistryImplementor

deRegisterChild

public void deRegisterChild(ServiceRegistryImplementor child)

Description copied from interface: ServiceRegistryImplementor

When a registry is created with a parent, the parent is notified of the child via this callback.

Specified by:

deRegisterChild in interface ServiceRegistryImplementor

resetParent

public void resetParent(@Nullable BootstrapServiceRegistry newParent)

Not intended for general use. We need the ability to stop and "reactivate" a registry to allow experimentation with technologies such as GraalVM, Quarkus and Cri-O.

fromRegistryOrChildren

public <T extends Service> @Nullable T fromRegistryOrChildren(Class<T> serviceRole)

Specified by:

fromRegistryOrChildren in interface ServiceRegistryImplementor

fromRegistryOrChildren

public static <T extends Service> @Nullable T fromRegistryOrChildren(Class<T> serviceRole,
 ServiceRegistryImplementor serviceRegistry,
 @Nullable Set<ServiceRegistryImplementor> childRegistries)

reactivate

@Internal
public void reactivate()

Not intended for general use. We need the ability to stop and "reactivate" a registry to allow experimentation with technologies such as GraalVM, Quarkus and Cri-O.
