Class ICUService.SimpleFactory

java.lang.Object

com.ibm.icu.impl.ICUService.SimpleFactory

All Implemented Interfaces:

ICUService.Factory

Enclosing class:

ICUService

public static class ICUService.SimpleFactory
extends Object
implements ICUService.Factory

A default implementation of factory. This provides default implementations for subclasses, and implements a singleton factory that matches a single id and returns a single (possibly deferred-initialized) instance. This implements updateVisibleIDs to add a mapping from its ID to itself if visible is true, or to remove any existing mapping for its ID if visible is false.

Field Summary

Constructor Summary

Constructors

Constructor	Description
SimpleFactory(Object instance, String id)	Convenience constructor that calls SimpleFactory(Object, String, boolean) with visible true.
SimpleFactory(Object instance, String id, boolean visible)	Construct a simple factory that maps a single id to a single service instance.

Method Summary

Modifier and Type	Method	Description
Object	create(ICUService.Key key, ICUService service)	Return the service instance if the factory's id is equal to the key's currentID.
String	getDisplayName(String identifier, ULocale locale)	If this.id equals id, returns id regardless of locale, otherwise returns null.
String	toString()	For debugging.
void	updateVisibleIDs(Map<String,ICUService.Factory> result)	If visible, adds a mapping from id -> this to the result, otherwise removes id from result.

Constructor Detail

SimpleFactory

public SimpleFactory(Object instance,
                     String id)

Convenience constructor that calls SimpleFactory(Object, String, boolean) with visible true.

SimpleFactory

public SimpleFactory(Object instance,
                     String id,
                     boolean visible)

Construct a simple factory that maps a single id to a single service instance. If visible is true, the id will be visible. Neither the instance nor the id can be null.

Method Detail

create

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

Return the service instance if the factory's id is equal to the key's currentID. Service is ignored.

Specified by:

create in interface ICUService.Factory

updateVisibleIDs

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

If visible, adds a mapping from id -> this to the result, otherwise removes id from result.

Specified by:

updateVisibleIDs in interface ICUService.Factory

getDisplayName

public String getDisplayName(String identifier,
                             ULocale locale)

If this.id equals id, returns id regardless of locale, otherwise returns null. (This default implementation has no localized id information.)

Specified by:

getDisplayName in interface ICUService.Factory

toString

public String toString()

For debugging.

Overrides:

toString in class Object

Returns:

a printable representation of this object.
