Pierre De Rop	452f438	2010-06-21 09:46:37 +0000	[diff] [blame]	5	This sample shows a basic "SpellChecker" application which provides a Felix "spellcheck" GOGO shell
				6	command. The GOGO "spellcheck" command accepts a string as parameter, which is checked for proper
Pierre De Rop	7e98d67	2010-07-03 21:56:18 +0000	[diff] [blame]	7	existence. The SpellChecker class has a required/multiple (1..N) dependency over every available
Pierre De Rop	452f438	2010-06-21 09:46:37 +0000	[diff] [blame]	8	"DictionaryService" services, which are internally used by the SpellChecker command, when checking
Pierre De Rop	4c13848	2010-07-03 22:25:18 +0000	[diff] [blame]	9	word existence.
Pierre De Rop	d9c4e3c	2010-05-24 21:42:18 +0000	[diff] [blame]	10
				11	A DictionaryService is defined using a FactoryConfigurationAdapterService annotation, allowing to
Pierre De Rop	10839cc	2010-07-04 21:07:59 +0000	[diff] [blame^]	12	instantiate many "DictionaryService" instances from webconsole. This annotation actually
Pierre De Rop	452f438	2010-06-21 09:46:37 +0000	[diff] [blame]	13	registers a ManagedServiceFactory into the Registry, and you can specify some meta type
Pierre De Rop	10839cc	2010-07-04 21:07:59 +0000	[diff] [blame^]	14	informations in the annotation, allowing to configure the DictionaryService words and language from
				15	WebConsole.
				16	Each time you instantiate a factory configuration whose factory pid equals "Dictionary Services",
Pierre De Rop	7e98d67	2010-07-03 21:56:18 +0000	[diff] [blame]	17	then a corresponding "DictionaryService" service is instantiated and is then injected
Pierre De Rop	452f438	2010-06-21 09:46:37 +0000	[diff] [blame]	18	into the SpellChecker service. So, before testing, you first have to go to webconsole
Pierre De Rop	7e98d67	2010-07-03 21:56:18 +0000	[diff] [blame]	19	Configuration panel, and specify some dictionaries (see the "Dictionary Services" Factory PID).
Pierre De Rop	452f438	2010-06-21 09:46:37 +0000	[diff] [blame]	20	Then, go to the felix GOGO shell, and you will then see the "spellcheck" command (when typing
				21	"help").
Pierre De Rop	d9c4e3c	2010-05-24 21:42:18 +0000	[diff] [blame]	22
				23	Notice that in the sample, you will also find a DictionaryAspect Service (DictionaryAspect.java), which
Pierre De Rop	10839cc	2010-07-04 21:07:59 +0000	[diff] [blame^]	24	decorates the EnglishDictionary service, by adding some additional words to it.

Pierre De Rop	804f4be	2010-04-25 22:57:56 +0000	[diff] [blame]	26	How to test:
				27
				28	1) Install the following bundles:
				29
				30	org.apache.felix.configadmin
				31	org.apache.felix.metatype
Pierre De Rop	7e98d67	2010-07-03 21:56:18 +0000	[diff] [blame]	32	org.apache.felix.http.jetty (from trunk, because the latest released version seems to have a problem)
Pierre De Rop	804f4be	2010-04-25 22:57:56 +0000	[diff] [blame]	33	org.apache.felix.webconsole
				34
				35	org.apache.felix.dependencymanager
				36	org.apache.felix.dependencymanager.shell
				37	org.apache.felix.dependencymanager.runtime
				38	org.apache.felix.dependencymanager.samples.annotation
				39
				40	2) Start felix
Pierre De Rop	4c13848	2010-07-03 22:25:18 +0000	[diff] [blame]	41	3) Go to web console: in the Configuration panel, edit the "Dictionary Services"
Pierre De Rop	452f438	2010-06-21 09:46:37 +0000	[diff] [blame]	42	Configuration, add some dictionaries. By default, an English dictionary is displayed. Just
Pierre De Rop	10839cc	2010-07-04 21:07:59 +0000	[diff] [blame^]	43	click on "save", then click on your refresh web browser: you will see a new dictionary service
Pierre De Rop	452f438	2010-06-21 09:46:37 +0000	[diff] [blame]	44	instance. At this point, a DictionaryService service will be enabled (with the service property "lang=en"),
				45	and the SpellCheck component will be injected with it. Then you should see the "spellcheck"
Pierre De Rop	7e98d67	2010-07-03 21:56:18 +0000	[diff] [blame]	46	command, when typing "help" on the gogo shell.
Pierre De Rop	804f4be	2010-04-25 22:57:56 +0000	[diff] [blame]	47
				48	5) Just type "spellcheck hello", and the command should reply a fantastic message, like "word hello is correct".
Pierre De Rop	804f4be	2010-04-25 22:57:56 +0000	[diff] [blame]	49
Pierre De Rop	10839cc	2010-07-04 21:07:59 +0000	[diff] [blame^]	50	6) You can also click on the "Aspect Dictionary" button, in order to decorate the english dictionary with some
				51	custom words.
Pierre De Rop	d9c4e3c	2010-05-24 21:42:18 +0000	[diff] [blame]	52	By default, the "aspect" word is pre configured, but you can click on the "+" button in order to add more words.
Pierre De Rop	10839cc	2010-07-04 21:07:59 +0000	[diff] [blame^]	53	Then click on Save. At this point, the English DictionaryService will be decorated with the aspect service.
Pierre De Rop	d9c4e3c	2010-05-24 21:42:18 +0000	[diff] [blame]	54	So, now, if you type "spellcheck aspect", then the message: "word aspect is correct" should be displayed.
