A Service provides access to service objects that implement a particular service, e.g. transliterators. Users provide a String id (for example, a locale string) to the service, and get back an object for that id. Service objects can be any kind of object. The service object is cached and returned for later queries, so generally it should not be mutable, or the caller should clone the object before modifying it.

Services 'canonicalize' the query id and use the canonical id to query for the service. The service also defines a mechanism to 'fallback' the id multiple times. Clients can optionally request the actual id that was matched by a query when they use an id to retrieve a service object.

Service objects are instantiated by Factory objects registered with the service. The service queries each Factory in turn, from most recently registered to earliest registered, until one returns a service object. If none responds with a service object, a fallback id is generated, and the process repeats until a service object is returned or until the id has no further fallbacks.

Factories can be dynamically registered and unregistered with the service. When registered, a Factory is installed at the head of the factory list, and so gets 'first crack' at any keys or fallback keys. When unregistered, it is removed from the service and can no longer be located through it. Service objects generated by this factory and held by the client are unaffected.

ICUService uses Keys to query factories and perform fallback. The Key defines the canonical form of the id, and implements the fallback strategy. Custom Keys can be defined that parse complex IDs into components that Factories can more easily use. The Key can cache the results of this parsing to save repeated effort. ICUService provides convenience APIs that take Strings and generate default Keys for use in querying.

ICUService provides API to get the list of ids publicly supported by the service (although queries aren't restricted to this list). This list contains only 'simple' IDs, and not fully unique ids. Factories are associated with each simple ID and the responsible factory can also return a human-readable localized version of the simple ID, for use in user interfaces. ICUService can also provide a sorted collection of the all the localized visible ids.

ICUService implements ICUNotifier, so that clients can register to receive notification when factories are added or removed from the service. ICUService provides a default EventListener subinterface, ServiceListener, which can be registered with the service. When the service changes, the ServiceListener's serviceChanged method is called, with the service as the only argument.

The ICUService API is both rich and generic, and it is expected that most implementations will statically 'wrap' ICUService to present a more appropriate API-- for example, to declare the type of the objects returned from get, to limit the factories that can be registered with the service, or to define their own listener interface with a custom callback method. They might also customize ICUService by overriding it, for example, to customize the Key and fallback strategy. ICULocaleService is a customized service that uses Locale names as ids and uses Keys that implement the standard resource bundle fallback strategy.

public Interface ICUService.Factory

Known Direct Implementers: com.ibm.icu.impl.ICUService.SimpleFactory, com.ibm.icu.impl.ICULocaleService.LocaleKeyFactory

Factories generate the service objects maintained by the service. A factory generates a service object from a key, updates id->factory mappings, and returns the display name for a supported id.

Method Summary

Modifier and Type	Method and Description
public Object	create(ICUService.Key key, ICUService service) Create a service object from the key, if this factory supports the key.
public String	getDisplayName(String id, ULocale locale) Return the display name for this id in the provided locale.
public void	updateVisibleIDs(Map<String, ICUService.Factory> result) Update the result IDs (not descriptors) to reflect the IDs this factory handles.

Method Detail

create

back to summary

public Object create(ICUService.Key key, ICUService service)

Create a service object from the key, if this factory supports the key. Otherwise, return null.

If the factory supports the key, then it can call the service's getKey(Key, String[], Factory) method passing itself as the factory to get the object that the service would have created prior to the factory's registration with the service. This can change the key, so any information required from the key should be extracted before making such a callback.

getDisplayName	back to summary
public String getDisplayName(String id, ULocale locale) Return the display name for this id in the provided locale. This is an localized id, not a descriptor. If the id is not visible or not defined by the factory, return null. If locale is null, return id unchanged.

updateVisibleIDs

back to summary

public void updateVisibleIDs(Map<String, ICUService.Factory> result)

Update the result IDs (not descriptors) to reflect the IDs this factory handles. This function and getDisplayName are used to support ICUService.getDisplayNames. Basically, the factory has to determine which IDs it will permit to be available, and of those, which it will provide localized display names for. In most cases this reflects the IDs that the factory directly supports.

public Class ICUService.Key

Class Inheritance

java.lang.Object
com.ibm.icu.impl.ICUService.Key

Known Direct Subclasses

com.ibm.icu.impl.ICULocaleService.LocaleKey

Keys are used to communicate with factories to generate an instance of the service. Keys define how ids are canonicalized, provide both a current id and a current descriptor to use in querying the cache and factories, and determine the fallback strategy.

Keys provide both a currentDescriptor and a currentID. The descriptor contains an optional prefix, followed by '/' and the currentID. Factories that handle complex keys, for example number format factories that generate multiple kinds of formatters for the same locale, use the descriptor to provide a fully unique identifier for the service object, while using the currentID (in this case, the locale string), as the visible IDs that can be localized.

The default implementation of Key has no fallbacks and has no custom descriptors.
