Interface Services

All Superinterfaces:

Locator

public interface Services
extends Locator

Services is the registry for HK2 services. In earlier versions this was referred to as the Habitat.

Services can be dynamically added to this instance or looked up. Services can also be implicitly added to HK2 by annotating the class with the @Service annotation.

Services are organized in a parent-child structure. Whenever services are being located, a parent search first algorithm is used.

Method Summary

Collection<Binding<?>>	getBindings() Retrieve the collection of all registered bindings in this instance as well as in the parent service instance(s).
Collection<Binding<?>>	getBindings(Descriptor descriptor) Retrieve the collection of existing bindings in this as well as in parent service registries that matches the Descriptor.
Collection<Binding<?>>	getDeclaredBindings() Retrieve the collection of all registered bindings in this, and only this, Services instance.
Collection<Binding<?>>	getDeclaredBindings(Descriptor descriptor) Retrieve the collection of registered bindings in this, and only this, Services instance that match the Descriptor argument.
Services	getDefault() Retrieves the default Services registry.
Services	getServices(String moduleName) Retrieves the service registry given a module name.

Method Detail

getDefault

Services getDefault()

Retrieves the default Services registry. This can be thought of as the root.

Returns:

the default, root service registry

getServices

Services getServices(String moduleName)

Retrieves the service registry given a module name.

Parameters:

moduleName - the module name, or null for the default services registry

Returns:

the service registry, or null if the service registry does not exist

bindDynamically

DynamicBinderFactory bindDynamically()

Allow dynamic additions to this service registry.

Returns:

a DynamicBinderFactory instance to add services after this services has been initialized.

getDeclaredBindings

Collection<Binding<?>> getDeclaredBindings()

Retrieve the collection of all registered bindings in this, and only this, Services instance.

Returns:

a non-null collection of service bindings

getDeclaredBindings

Collection<Binding<?>> getDeclaredBindings(Descriptor descriptor)

Retrieve the collection of registered bindings in this, and only this, Services instance that match the Descriptor argument.

A Descriptor matches if it's attributes are equal, or specified as null. A Descriptor with all null attributes will therefore match all services in this services registry.

Parameters:

descriptor - the descriptor used for matching, or null for all

Returns:

a non-null collection of service bindings matching the argument

getBindings

Collection<Binding<?>> getBindings()

Retrieve the collection of all registered bindings in this instance as well as in the parent service instance(s).

Returns:

a non-null collection of service bindings

getBindings

Collection<Binding<?>> getBindings(Descriptor descriptor)

Retrieve the collection of existing bindings in this as well as in parent service registries that matches the Descriptor.

A Descriptor matches if it's attributes are equal, or specified as null. A Descriptor with all null attributes will therefore match all services in this services registry.

Parameters:

descriptor - the descriptor used for matching, or null for all

Returns:

a non-null collection of service bindings matching the argument
